Welcome to ���������¼� engineering the future podcast. Today we're talking about what cybersecurity will look like 30 years from now. From passwords and encryption to the dangers and impact of cyber warfare between nations.

Hammond Pearce:����

We rely on technology for so much of what we do. It's one thing if our bank goes down. It's another thing if our municipal water supply goes down. So these threats are very real, and we ignore them at our peril.

Neil Martin:����

That's Dr Hammond Pearce, a ���������¼� cyber security expert who once worked at NASA. On Engineering the Future, we speak to academics and industry leaders who are embracing cutting edge ideas and pushing the boundaries of what is truly possible. Join us as we discover how world changing action starts with fearless thinking on Engineering the Future of Cybersecurity.

Neil Martin:����

Hello and welcome to Engineering the Future of cybersecurity. My name is Neil Martin, and I'm a journalist and stem communicator working in the Faculty of Engineering at ���������¼�. Joining me today to discuss how cybersecurity will evolve over the next 30 years is Dr Hammond Pearce, a lecturer from ���������¼� School of Computer Science and Engineering. Hammond's research focus is related to the cybersecurity of embedded and cyber physical systems, and he is particularly interested in how AI might be leveraged for new design strategies. He has previously worked in several industry positions, including as a full stack web developer and at NASA's Ames Research Centre in California. Welcome Hammond.��

Hammond Pearce:����

Hi, Neil. Great to be here.��

Neil Martin:����

Thank you. Also with us is Sharat Madanapalli who has over a decade of experience crafting intelligent systems that solve real world business problems. Sharat is a Director of Intune AI and has previously held roles as head of AI and data at innovative startups, delivering measurable results across industries. Through Intune AI, he currently guides executives and teams in leveraging AI's transformative potential, empowering organisations to gain sustainable competitive advantages in an increasingly AI driven world. Hello, Sharat.

Sharat Madanapalli:��

Hi Neil, thank you so much for having me. This is my first podcast. So excited to be here.

Neil Martin:����

You’re obviously both experts in this field, and it seems to me that artificial intelligence is evolving at an ever-rapid pace. Cybersecurity threats are becoming increasingly sophisticated, and the need to protect our infrastructure, our data and our privacy has never been more vital. Every week we read a new headline about a major cyber attack on key industries such as banking, medical, manufacturing and technology, and that's without even more worrying, alleged state level operations that we might class as cyber warfare being waged in places like the Middle East, Ukraine, USA and China. There's obviously a big concern here. So Hammond, I might ask you first, why do you think cyber security is so important, and what are the dangers if we don't take it seriously?

Hammond Pearce:��

That’s a great question Neil to start us off. So I think one of the first things that we need to consider is that we as Australia and as western society, more broadly, and even as the whole world, are moving towards a future where we rely almost entirely on technology from every aspect of our lives, from the farming equipment that is being used to grow crops to water management systems in our city to traffic lights to trains which are being scheduled by computers to obviously, the more visible computers like things that are running our banks, things that are running our cell phone networks. We rely on Technology for so much of what we do that not taking seriously the risks into that technology and the threats to that technology opens us up to a huge number of possible consequences. You know, it's one thing if our bank goes down. It's another thing if our municipal water supply goes down. We've already seen in Australia, for instance, back in 2023 that the ports were shut down and Sydney, DP World was shut down after a major cyber attack. So these threats are very real, and we ignore them at our peril.��

Neil Martin:����

Sharat, you're working in business. Do you feel that the business world is taking these threats seriously.

Sharat Madanapalli:����

I think the seriousness has been increasing more recently with the widespread attacks that are going on, so everybody's a lot more aware. And there are people specifically put in those positions called CISO source with like Chief Information Security Officers, who have been tasked to take the security aspect of the business really seriously. And there is, like now, a plethora of technologies to protect against attack to other technologies, right? So there's a lot of security tooling out there, security companies who are helping businesses protect and there are people being employed to take that seriously.

Neil Martin:����

And you talk about the technology there. would that include artificial intelligence, I guess?

Sharat Madanapalli:��

Yes. AI and the way it has evolved, recently reaching now in the hands of millions of users. ChatGPT actually was the fastest growing app so far in two months, it has reached 100 million users, like far surpassing Instagram. And this one doesn't even have social media effects, right? There are no friends on the platform. But AI has been now put in hands of a lot of people, which of course, creates threats and opportunities alike.

Neil Martin:����

So that actually leads me into a very, I think, interesting question. Is AI going to protect us from cyber attacks, or is it going to be used more easily by bad actors to attack systems?

Hammond Pearce:����

I think it can be both. So, for instance, I've been involved with a competition for the last couple of years called the AI Hardware Attack Challenge, where we literally get people to use chat GPT to try and break into particular types of computer systems and add back doors and things like that. And we've demonstrated that that can be done so people who aren't knowledgeable can reach for ChatGPT, and we give them a challenge. We say, here is a computer system, add a back door to this computer system, and then they can use tools like ChatGPT to help them do that, which is the whole point of the exercise, to see if that makes it easier, which it does. But of course, the inverse of that is true as well. Just like you can ask ChatGPT or other AIs to help you break into something, you can also ask them to help you defend something. And one of the major strengths here is that AI and other AI technologies, not just ChatGPT, but all classic AI and what have you as well, they can categorise and search information very quickly, very efficiently, and as we move into a world that becomes more dominated by computers, there is so much more data to sift through. These tools and technologies can actually help us do that, to help us find things that are out of the ordinary, to help us find computers that are misbehaving, or people that are using the computers to misbehave. There's a lot of potential for AI-powered defense as well as AI-powered attack.��

Neil Martin:����

Do you think there is some kind of space race, or there's a battle here between, like, the good guys and the bad guys as to who can use AI the most efficiently or in the best way, and they're battling against each other.��

Sharat Madanapalli:����

I think this is not new with AI. Like, every time a new technology has been put out there, there were people using it in different ways, right? So it's AI is, of course, I would say, the most widely adopted technology. And I think the key power with Gen AI these days is any human can use human language to access intelligence that has never been there before, right. Even if you see one decade ago when we were still building in our PhDs, building systems to protect against attacks. You required a lot more technical sophistication. You need to understand statistics. You couldn't do machine learning just off the board and like access intelligence, right? You need to know math. You need to know programming, then you can build a system, or, let alone use a system, right? But that has now slowly going away. Now it's democratised intelligence, accessible to everybody, anyone can use it and for any purpose. So the risks are like coming with that access I feel.��

Neil Martin:����

Do you feel that it's broader attacks rather than deeper attacks, or is it both at the same time?

Hammond Pearce:����

I think it can be both. So there are AI companies at the moment. One example that I know because I have a friend who works there, is one called Expo, and that's a company that's trying to leverage things like large language models to automatically scan your websites, find vulnerabilities and then find ways to sort of break into your technology. Now they're offering this as a service. So you use their services to then find vulnerabilities and mistakes in your own website, so that then you can fix it, right? So you get this AI powered attacker, and you go, Hey, AI, I want you to try and break my system. Then if you work out how to do that, tell me, then I can try and fix it right? So there's those sorts of benefits there, but a tool like that could also be constructed and leveraged just for attacker purposes as well. I think one of the difficult things when it comes to cyber security, and this is true across the board, even before AI, the defender needs to get everything right. So if you're trying to prevent someone from breaking into your website, or even if you want to think about it in the form of a physical building like a bank. If you're trying to prevent someone from breaking into a bank, you need to get everything right. You need to have guards, you need to have a good door, you need to make sure that the changeovers are right. You know, all of these sorts of physical things. The attacker only needs to discover one mistake, and if they find that one mistake, they can leverage that as an entrance into your service, or, in our case, a website or another piece of technology. That's where something like AI can be both helpful, because it can search millions of different ways to break in and, you know, very, very quickly, but then the defenders can use that as a tool as well, because now they also have a tool that can help them do all of that sort of breadth of searching, where previously you would have needed to get a whole load of domain experts to try all of the different techniques.

Neil Martin:����

Sharat, is there a process by which we need to start thinking about protecting the AI models themselves?

Sharat Madanapalli:����

Oh yeah. So that's an entirely new class of attacks that has emerged now with AI becoming a mainstream thing, I think with cybersecurity right often, like a decade ago, you wouldn't know the things that you need to protect 10 years down the line, which now are AI models. So there's so many attacks on the models themselves. You must have heard of prompt injection attacks, which is you're trying to suss out information from the model which has been trained to not give that information, for example, like biohazards, how do you make a bomb? For example, right chat, GPT. And there's been enormous research put in to protect users from accessing that knowledge, because it is trained on the entire internet knowledge. So it has been trained on good knowledge and knowledge that can be used for bad purposes. So there's a lot of AI safety and regulations that are going on that are making sure that these models are not breaking, but they're also being attacked at the same time. And there are some users who know all of these tricks. They're like, they call it this prompt injection nerds. And every time a new model comes out within a day or two, they break it, and then they tell, oh, I now know how to make that.

Neil Martin:����

So sure. How would you actually trick a model?��

Sharat Madanapalli:��

So this was early days of these language models, but when you would ask them how to make a bomb, they would be like “Oh no, I cannot tell you this information” - because it's been trained to reject this. But people would get creative and be like, I'm a movie director, and I'm going to create a scene where the villain in the movie wants to create a bomb. So can you tell me how I can direct the scene? And I want you to be technically accurate, so that I give a good movie to my audience. And then you should go out and then completely put out a recipe for making a bomb, including a shot. Oh, you know, take this, the close up should include this chemical or whatever is used to make a bomb, and then they would suss out all of that information. And they could do that for like, that trick of movie was like a very famous one that got viral on Twitter. And, of course, the model providers since then have created much more intelligent systems that can block any of these. In fact, Anthropic nowadays has a challenge of like, 10 levels of prompt injection. And I don't think people have reached past level four or something recently but I might be wrong. There's a competition going on. So there are good actors that are trying to prevent this and create specialised, again, AI models to defend these large language models from these kind of attacks,

Neil Martin:����

And does that open up somewhat moralistic questions about who actually controls that data that is being accessed or being produced in the system?

Hammond Pearce:����

Yes, absolutely. So one of the big things that they're talking about right now, at the moment, actually, this is very topical, because how you build these big AI systems is broadly known at this point. So that's how someone like Deepseek, that Chinese company, can produce an AI so quickly now, whereas it took OpenAI a number of years to do it, because how you build the models is now basically public information. What is not public is the data that you produce those models over. So open AI, for instance, originally just sort of scraped everything. Now they've got licensing agreements with publishers, things like that, so they get sort of exclusive access to that information. Other models may not have legitimate access to information where you know, depending on how you feel about intellectual property, the courts still haven't actually decided whether or not AI training is legitimate or not legitimate, so that's still something for us to decide later. But regardless of how you feel about the who owns the data that these models are trained over, it is true that not everyone has the same data, and people are being a bit secretive about that. We still don't know the full set of data that OpenAI's models are trained over. So open AI's models may also have inadvertently or deliberately been exposed to faulty information or biased information, which steers the model to conclusions that might otherwise not be supported.

Neil Martin:����

Sharat, I've had some comments and read some articles about AI being kind of implemented in your own devices, which may help against attacks against your own personal information to protect your own privacy. Can you talk a little bit about that?��

Sharat Madanapalli:��

I think on device, AI has been growing in popularity ever since our mobile devices, and let's say our laptops, are growing in compute power. So there are specialised chips that can run these models, which traditionally were really hard to run on. They require GPUs. And by GPUs, I mean graphical processing units, which are these specialised computer chips, just like your processors, that can do a lot of mathematical computations in parallel, that are really good to run these AI models, because they're a lot of math behind the scenes, even like the ChatGPT models today, require server farms to run them right at scale, but we are able to now distil smaller models that are still capable of running for like small tasks, like summarise this email thread and so on, on your device itself, so that the access is limited to you, and the data stays on your device. So there's a lot more security that comes with it, because a lot of attack vectors are now not possible. It's like, if you compare it to the bank system, it just like having money in your own safe house, right, dollars and dollars locked up. So that, I think, has a lot of advantages, not only security wise, but there's also performance. There's like, very low latency requirements. Now the model is right on your device, and by low latency, I mean the response being really quick. So like your face ID, the moment you show your face to it, it just unlocks straight away, without having to do the network round trip, going to the servers and then coming back and saying, ‘Okay, now you can go in’. So you can imagine, if your internet is really slow, you cannot get into your phone. This, I think, can evolve into something much more bigger, where it's a personal assistant. So it is kind of looking at your screen, helping you probably, like, we can build systems that can help you be more secure online. It could detect phishing attacks, Let's say you open up a link, the AI that's like, kind of looking over your shoulder, hopefully, with a positive intent, can help you out saying, hey, that's something fishy. Do not click on it. That's possible.

Neil Martin:����

I guess there are certain groups in society that might be more susceptible to those kind of phishing attacks, and having that assistance, I mean. I'm thinking of my own mother, for example, she gets a message on her phone. It's very difficult for her to understand whether or not it's a real message from the bank. It says, Oh, your bank account has been suspended. She gets very worried, you know, her mentality is, I need to sort this out. I press the link. Hammond, how easy do you think it is for people to be fooled by them?��

Hammond Pearce:����

Well, it's actually very interesting that you should ask me that, because ���������¼� actually likes to send, you know, simulated phishing emails to its employees almost continuously. So every two or three weeks I would say, you know some, ‘Oh, you've won an award’, ‘Oh, someone's sent you this conference PDF’. Oh, you know this or that, and they always look a little bit suspicious. And so I dutifully click the report button, and then it tells me, well done. You know, you didn't get fooled this time. But last Christmas, actually, I don't know. I was tired. I was at home. I was going to bed, I think, and I was on my phone, and a little pop up saying,’Oh, Merry Christmas from ���������¼�. Click on the little personalized Christmas card’. And I was like, Oh, how sweet that someone has sent this to me. So I clicked it, and then it was like, boom, we got you! You finally clicked one of our fishing links. And I was like, Oh, for goodness sake, it's Christmas. Take a break. But yeah, so, you know, even I am a security expert, I catch almost all of these damn emails, and even I managed to click on a simulated phishing email that one time. So yeah, absolutely, it's hard for people to keep up. And you know, this is what attackers do. They will relentlessly pursue you if they decide that you're a mark, or if they decide that you're the end to whatever system they want.��

Neil Martin:����

Talking about devices, I might move on to something else with regards to cyber security that I've seen, and this is to do with passwords when we're logging on to our own personal computers or onto our phones. Do you think passwords might become a thing of the past in the future? Yeah,

Hammond Pearce:����

I think passwords are already beginning to be phased out, if you consider things like your modern Windows laptops or Mac laptops or cell phones or whatever, most of the time they like using tools like face ID now. We've got various biometric things like fingerprints. It's quite a lot of services try not to use passwords at all, particularly if you use sort of modern web apps. For instance, even Qantas, now I don't believe uses passwords for logging in. I believe it just asks you for a short pin your membership number and your surname, and then it just texts you to say, Are you logging in? Now? Is that an improvement over passwords? Texting is not a great way of authenticating people, because there's lots of ways of hijacking texts. But separately to that, is that better than passwords? Maybe a lot of people don't like having to remember long strings of numerals and passwords. They don't like that we tell them to change their passwords every year. People forget them. You were just talking about your sort of elderly relatives. I know my dad struggles to remember his passwords, so does my mum. So they inevitably end up just writing them on a piece of paper, or worse, like a notepad file on their computer, which you know, then if someone steals the computer, they can have access to everything. So yes, I think passwords are probably going to be on the way out to be replaced by some better technology. It still remains to be seen. What that better technology is. You know, whether it's some combination of biometrics, like what Apple and Microsoft are doing, whether it's just short pins on sort of trusted devices, or even things like smart cards or rotating codes that we all have to set up now for a variety of services.��

Neil Martin:��

I guess the issue with passwords has always been that they can be found out, they can be hacked, they can be somehow discovered. And I guess AI is accelerating that problem as well.��

Sharat Madanapalli:����

Definitely. I think one of the recent things that I was reading is the captures that you solve were initially designed for systems to detect that it's a human accessing it, but the models are getting so much better that the AI models are able to solve CAPTCHAs, and now it's like robots versus robots at this point. But even before that, I think password managers are super key, I would say, as an advice to people still not using that, even my mom is guilty of just saving it on her notes app. So I was recommending to her, please download a password manager. That way you just have to remember one password, and it remembers the rest of them for you, and can keep much more secure passwords in there.

Neil Martin:����

When I was researching this episode, I read some kind of very futuristic articles about potentially we might be using our brain waves in future, which obviously seems quite unique, and you would hope people couldn't break into your own brain waves, but who knows what we'll be capable of in the future. But do you see that being actually realistic, or is that kind of too much sci fi?��

Hammond Pearce:����

I think it would really depend on how they were accessing your brain waves. If everyone has to put on a special hat every time they get to their computer, that might get quite irritating quite quickly. I think there is a chance that we will see other types of technology being used for authentication. I know there's been lots of murmuring about using voice authentication, but at the same time as that, as Sharat just mentioned, with AI, there's lots of things that AI can do to try and mimic you, right? So if it can get enough records of your voice, you can already just download software to construct very realistic copies of people's voices just based off short snippets of them speaking. I wouldn't be surprised if you could clone my voice after listening to this podcast by using some of this open source software. So you know, that's where I would be going. Well, is the cloning software going to be able to breach these authentication mechanisms? Because if so, they're not going to be very good authentication mechanisms.��

Sharat Madanapalli:����

On that note, right? I've seen a recent article where not just audio, but video, has also been cloned. So this is a Hong Kong multinational company, and there was an attack where multiple execs were cloned, and there was one employee who was only the real human in that video call who was convinced by the CFO to transfer an amount of money, which is like millions of dollars. And yeah, the whole company lost that money. It was like the largest cyber attack using deep fake technology. So, I mean, it's hard, I guess, for a face ID to work, but like voice cloning, I think is, I've seen apps in, like, online websites these days that can do it on a 30 second clip, and they have your voice. You just give it text, and it just starts blurting out your voice.

Hammond Pearce:����

And that goes back to what you were saying earlier about phishing attacks as well. They're gonna get even scarier when you know your mum could get a phone call from you, Neil, that sounds like you being like, Hey, Mom, I'm in some trouble. You know, I need you to send $1,000 to this bank account. Would your mum then do that? You know that these are, these are very real attacks, and already some sort of well connected cyber security people are saying online. You know, if you want to take this seriously, if you think you might be a target of the attack, you probably need to set up like, special key phrases with your loved ones to be like, if I ever call you and ask for money, unless I say the term banana cake, you know, don't transfer the money because, you know, otherwise, it could be something that's being faked. So yeah, so there's a lot of potential risks. An attacks in here with this cloning stuff?��

Neil Martin:����

Sharat, I wanted to bring you back something you mentioned before about taking things off the cloud and having them more controlled by the user. I’ve read about the personalisation of information. I think that means you kind of keep it yourself a lot more, but you might correct me with that assumption. But how do you think personalised control of information could help individuals or organisations protect themselves from cyber threats such as maybe phishing and data breaches that you've mentioned?��

Sharat Madanapalli:����

There are two aspects right. One is personalization, which is when services you access are tailored to your needs, right? And that has been done with or without privacy. So privacy is when you have access to your data, and your data is private, right? But personalisation has been going on in in the social media world for a lot of time without your data being private to you. So what you watch, the content, like the news articles you consume, or the nowadays, the Tiktok reels you scroll through, often personalise your feed and you're given like, for example, I get a lot of AI videos on YouTube that's personalised service offered by YouTube to me that makes the content more and more engaging. But that doesn't mean what my preferences are known to YouTube, right? And similarly, so many, like billions of users, preferences are known to many of these social media companies, and they're using that to curate and convince you to come back on that platform. But that's not privacy. Like I did not explicitly tell them to pick up on my personal like there's there's nothing that says, ‘Hey, can you please feed in what you like and what you don't like? And we will recommend you based on that’. It just auto learns all of that, right? So that has been a debate for a long time, that, how are you learning without my consent? Right? And that also extends, like Hammond pointed out, to training the models themselves on like multiple of these personalisation data sets. But bringing back our conversation to privacy, I think these days, people are starting to be more aware of it, to know that, okay, how did it find out? Right? There are many instances of news articles I've seen that said I was just talking about this product, or about the service to my wife, and then suddenly, all of a sudden, I see an ad. Are they like listening in? And it's so hard to prove that or disprove that, right?��

Neil Martin:����

I think all the people saying that every single day is kind of the proof.

Sharat Madanapalli:��

But it's been hard, like people try to do, like scientific trials, to figure out if that's true or not, but there's no conclusive evidence that it's true. So personalisation has been going on for at least a couple of decades without, I guess, keeping privacy at the centre. But hopefully once people are aware that this is happening and this is going to impact their lives, and they start taking it seriously, then the businesses will start taking it seriously, because then they have incentives to make that happen. I think it's misaligned incentives that kind of create any push right to do something, but now that people are more aware, we have better incentives that are aligned to protect the privacy of people, and I think of the big tech companies, privacy has been taken I feel relatively seriously by Apple, who often like advertise that as well, that your data is on your device and they're not storing that. In fact, sometimes they came up with a unique VPN architecture where they're not even like logging anything. So it's a complete zero trust mechanism in which they're doing privacy. And by zero trust, I mean you do not trust anybody, anything, any organisation. So when multiple parties are involved, a zero trust system means nobody trusts anybody, and the technology is such that it can still work without requiring trust as a fundamental component. So I feel like that could it's hard to marry them traditionally personalisation and privacy, because you need data to figure out what the person likes, and feeding in everything is very cumbersome. So I think it'll evolve, and maybe AI is something that we can use to marry them both together.��

Neil Martin:����

I guess another thing, and I don't know whether this is exactly the same or slightly different, is maybe people might think I give my information to the bank, I give my information to my healthcare provider, and then a couple of months down the track, that bank or that healthcare provider gets cyber hacked, and all of my information is gone, and I trusted them with that information, and I didn't have any control. Do you think it's right for people to maybe think if I could retain all of that information myself, and it was only being given out as and when it was needed to be? Is that better or are the downsides to that as well?

Hammond Pearce:����

Yeah, I think it would be better. I think there is a tendency for companies to engage in what I would call surveillance capitalism, which I think is a term, if people are interested, they can look that up. So it's this idea that, as Sharat was saying, that companies can serve you better if they know every little thing about you. Now, whether or not they need to know everything little thing about you as a completely separate question, and what happens is that when they know every little thing about you, they themselves become valuable for cyber attacks, because now people can break in and steal everything. There's a few different schools of thought here. Sharat introduced a couple of them. I think there is a push from certain governments, possibly the European Union is the strongest one in this place to actually say, well, actually, we want you to consider that all of the private data that you hold on your customers is not an asset. That actually is a liability. We want you as a company to consider that there is a potential liability for you to own this data, and if that data gets stolen, we will hold you, you know, very financially at fault for that. So that's, you know, that's a school of thought that's slowly coming in, and there are regulations to support it. We haven't seen quite that level of enthusiasm over in the United States or in Australia, in terms of, you know, trying to flip the narrative on its head, with regards to, is data a good thing or a bad thing? I personally would prefer companies to try and know the least about you that they need to to offer the service. You know, why does every company need to know my date of birth? Why does every company need to know my address if they're never going to post me anything? You know? Why do companies need to retain my credit cards if I can just give them an authorization or just give it to them each time they need it? They don't need to remember any of this. But you know, then the other narrative is, well, it's convenient for them to know all of that thing. What if they one day do want to post you something, or you forget your password, and they need to work out another way of authenticating you? So there's a flip side to it. You know, I would prefer companies to know less about you, and I would personally prefer it if, as a society, we agreed that we did want to keep more of our personal details, personal so that, so as to prevent those kinds of situations from arising in the first place. But sometimes we don't have a choice. You know, if you want to use a bank or fly on an airline, and they ask you for all these details, you can't not provide them. It's not an option in the service to be like, well, actually, I'd rather not tell you this, but I still want your service. If the company says to get my products, you have to give me this information. Your only other option is to go to another company which may not be convenient or may not provide what it is you actually are looking for.

Neil Martin:����

Does centralising the information, though, make it slightly easier for the bad actors, because they know that if they get in through one door, it's like you were saying about getting into the bank. If you get into the bank, you can potentially steal millions of dollars that might be in the vault. If you break into one individual person's house, you might get their wallet. So in that respect, it makes it more attractive when all of the data is being collected into one big group that any cyber attack, is gonna get them a massive reward, right?��

Sharat Madanapalli:����

Yeah definitely. There's huge enough incentive for them to figure out how to break in. But with, like decentralised. I think that's what blockchain I think wanted to do, but I think it didn't get there, like with decentralised access and all of that. That would be an ideal world to live in, though, where you access your control, and you give almost a consent every time that any company wants to access that data. Think of it as like your wallet, and you let whenever it needs to access it, you're allowing them to and then after that, for a limited period of time, and then they cannot access it. Again, that would be a cool technology to build. But then again, there's a debate of, if somebody builds that technology, wouldn't they own the data? And then this whole thing between convenience and security comes up, all again.��

Hammond Pearce:��

Sharat mentioned that blockchains weren't necessarily a good technology for authentication in particular. It's a very interesting idea that this idea of the blockchain and how cryptocurrencies do it, is that you take ownership of some private key, right? They distil identity down to the purest digital form, which is this concept that I have a secret. It's called a private key. I'm the only one that knows it, but you everyone else in the world, you get a copy of something related to that private key. It's called a public key, and that it's got a relationship mathematically to my private key. And you can do some simple equations, not so simple equations, as it turns out, but you can do some math to verify that my private key, whenever I use it, matches the public key that you know I have. And so the way blockchains work fundamentally is I keep my private key private, and whenever I do something like spend some money or receive some money or do some transaction on the blockchain, it's really limited to kind of those two concepts for most of them, then you can use my public key to verify that. Am the person that I said that I am. The downside to this, of course, is that these public and private keys, they're just long strings of numbers. They're like passwords that are very difficult to remember, and if you lose them, there's almost no way to recover them. So this is the problem that cryptocurrencies in particular have. There's this famous fellow in England who threw away his hard drive that contained his private key on it, and now that private key is the key, quite literally, to some 10s of millions or hundreds of millions of pounds of cryptocurrency, and he can't access it because he threw his hard drive away. You know, that's not a system that we want to build identities and economics and monetary theory on.��

There's another technology which I'll bring up here. I'm not an expert in it, but I'm aware of it, which is called the zero knowledge proof. So the idea is that instead of a company, this is not the idea of zero knowledge proofs, but it's how they can be used. So the idea is, is that a company doesn't necessarily need to know your date of birth, for instance, but they might need to know that you're over 21 for instance, if you're gambling online or maybe you're buying alcohol, they need to know you're above a different age. They don't actually need to know your date of birth. They just need to know that you're above that cutoff date. So the idea is, is that you provide this way of proving to them that you're over that limit, or that you know any other information you're a resident of Australia for tax purposes, whatever you can provide a way of proving it to them without them actually knowing the root of the data. And so that's another technique that people have suggested, and they've said that perhaps the government could offer that as a service. Because again, you know the government nominally knows everything about you in a country like Australia. They know our driver's licenses, they know our passports, they know our tax data, so they know that you know the essential stuff. So maybe the government could offer as a service this way of proving certain things to companies without the companies actually getting a hold of that data themselves.��

Sharat Madanapalli:����

I think one equivalence I see that is it's been done similarly in the world of technology, where you use OAuth, so you use Google to sign into other platforms where Google tells that, hey, this is an authenticated user that you can use to sign into your website or service and so on. And many apps actually do that with face ID as well. So Apple gives them some token that is, hey, this is a legitimate user who has signed in, and then they connect that with their systems, so they do not have access to my face pictures or whatever, but they know that it's a user who is signed in and now can access the app. There is some Eco balance there, right? But we could do that for a lot more personal data, like names, date of birth and so on.��

Neil Martin:����

But I'm guessing that you're expecting cyber attacks on banks and healthcare and technology and to kind of continue, it's this continual battle between the good guys and the bad guys.��

Hammond Pearce:����

Yeah of course. So, I mean, in Australia, we had the Medi bank hack a few years ago where they stole so much personal data. Similarly, I think it was Optus. I want to say they had a big hack where, again, a whole load of data was stolen. So these kinds of thefts of huge amounts of personal data, they're very valuable to cyber attackers. They can do stuff with that data. They can sell it to other people who are interested. They can use it to perform identity theft. They can even sell it to things like pollsters and analytics companies that are trying to get people to vote in certain ways. For instance, the pollster, the famous one here is Cambridge Analytica, who actually purchased stolen data, whether they knew it was stolen or not from a researcher who had illegally or against the terms of service, acquired that data from Facebook users. So there's a lot of money in stolen private data.

Neil Martin:����

Do you think businesses are taking this seriously enough in terms of protecting data, in terms of making sure their own systems are safe?

Sharat Madanapalli:��

I think it depends on what stage you are of your business, I have seen startups, of course, be a lot less risk averse, so they are okay to take a bit of risk in the initial days until they prove product market fit. Probably the software is not as secure, but as you grow your user base, as you become a potential target for somebody to hack on, right? Like, if it's a small service serving 10 to 100 people, maybe the actors are not motivated enough to attack them and steal that data, right? But as you're growing big, so that's why I think the specialised personnel like CISOs and security engineers come into picture at a certain stage of the company where the company is big enough, and then that's the current reality now, is that the best way to do things or not, is another debate, but that's what I'm saying. The trends play out.��

Neil Martin:��

And you mentioned something before, Hammond, would you like to see more regulation implemented to maybe enforce these companies to do more?

Hammond Pearce:����

Yes, I think that one of the big challenges right now is that there are not large punishments for companies that don't look after your data properly, that are not responsible shepherds. So this is something, again, that the EU is trying to do, to say that, well, if you're a bank or if you're an insurance company or whatever, and you've got tons of people's private and very sensitive information if it gets stolen from you, you know, we want to hold you really, really responsible. I think that's something that a lot of countries could learn from. I would like to see much larger compulsory fines and things like that. But then, of course, there's the flip side, when you make the punishment so severe, then companies will go, oh, I had data stolen. I'm not going to tell anyone, because then we're going to get a big, big fine. So it's a very difficult line to follow right now, because the penalties are low. Perhaps companies are more forthright about when something goes wrong, but you know, it would be nice if they would actually just do the protections properly in the first place, so that thefts were more difficult. And you do see that when companies have had a theft and people write up reports, they go, ‘Oh, well, you know, they were doing so little correctly’. You know, they weren't encrypting data at rest. They were using default passwords. They just had it all on an unprotected bucket in Amazon Web Services. You know, there's so many things that people just do wrong and without any thought to the consequences, because they're not worried about that. And of course, they're not data privacy is not going to earn the money. This is the thing that Sharat was talking about with misaligned incentives. Security is only ever a cost for your business until it goes wrong, then it becomes a liability. So it would be nice if there were better regulations to try and make it a liability always, so that people were more motivated to try and do the right thing.

Sharat Madanapalli:����

And it's not that the companies cannot do it right, like I've seen products that are launched in rest of the world first, and they often take a few months to then launch it in Europe, because of all of those regulations that are enforced by European Union to make sure that they adhere to that. And once they do that, I think the rest of the systems are, of course, automatically upgraded to be more safe and secure. But I've seen every launch like, I think even ChatGPT, if I'm not wrong, was launched first in, let's say, America, and then every feature, they say it's coming to Europe soon, right? It's where they need to make sure that things are all battle tested for security and data privacy and data residency requirements that the European Union enforces on companies.

Neil Martin:����

We talk about security there, and I want to move on to something else, security of sovereign nations, security of countries. Has cyber security become a critical component in modern warfare Hammond? And what are those cyber threats and the greatest risk to national securities?

Hammond Pearce:����

So yes, cyber security has definitely become another tool for a modern military. The US in particular, has got a cyber core. I can't remember the exact name of it off the top of my head, but they have trained hackers working for the government, doing both offense and defense, and you can see why. So yes, in recent conflicts, we've had various cyber attacks. We've had in Ukraine in 2015 and in other years as well, because it's happened multiple times, big cyber attacks have taken out big parts of their power grid by malicious hackers logging in and causing chaos. That's also happened almost in Australia, where actually just normal hack as a hacking group has been trying to break into the Queensland power grid, and in 2021, nearly disrupted over three gigawatts of power. Fortunately, it was stopped before it happened. But this kind of all goes back to sort of the first major state sponsored attack, that cyber attack, which was Stuxnet. So this was back in sort of 2010 when probably Mossad and the US National Security Agency and other intelligence agencies in Israel and the US worked together to come up with a particular computer virus that could get in and compromise the Iranian nuclear program. So that was sort of the first major really confirmed. Hey, this is a nation state that rode a virus to compromise another nation's infrastructure. And ever since then, you know, attacks have grown, not just by nation states against one another, but obviously that has happened, particularly in the modern era, with the war in Ukraine and the power grid there in particular, has been victim to multiple attacks, but also just groups. So hacking groups, one that comes to my mind right now is the Colonial Pipeline, one a few years ago in the United States, where a hacking group, not deliberately, apparently, took out a pipeline running down the eastern seaboard in the US, causing gas prices to spike. And nominally, they said, whoops, we were actually just trying to get it to the banking data of the company. Our bad, we didn't realize that was going to shut down the pipeline. So there's lots of different risks here. And of course, governments are looking at this and being like, hang on, you know, some guys, or some people in a in a hacking group have just managed to disrupt a whole country's gas network just with some computers. You know, that's the sort of thing that a few years ago would have required huge invasion forces and planes and bombs and things like that to do, and they can just do it with a computer. And. So of course, modern militaries are going to be looking at, hey, you know, can we just disable a country remotely? Can we just log in, turn their power off, log in, turn their water off, shut their traffic down, shut their transport down. And I think that there is a very real risk of that. So countries, particularly Australia, we've got the ASD here that are also helping to secure the country as well from cyber attacks are going, what's our weakest points? How do we secure those weak points? What do we need to do so that a nation state cyber attacker can't necessarily get into our infrastructure? But there are so many difficulties there. It becomes a much bigger question than, how do you just stop a rogue hacker or an individual particularly when you've got things like, you know, Australia doesn't manufacture most of its computers. We get computers in from overseas, from Asia and from the US and from Europe. We get parts from everywhere. So how do you secure a computer that's not even built in your country? You know, what is hidden inside it? And there's all these different kinds of threats that are implausible when you go, Well, you know, there's just one hacker that's working from a room somewhere to when you go, Okay, this is an attack with the entire force of the United States behind it, all of their money, all of their assets, all of their control. What can they do? And I think the most sort of a cyber attack sort of not, but the most recent example of this that I think has the most impact was the pager attack that Israel did on Hezbollah, right? So they created a fake company. They created fake pages, which then Hezbollah purchased, and then in those pages, as well as them being a functional device, were explosives, so that after a couple of years of them being in the field, they then triggered them and killed a load of people. So yeah, it's quite terrifying to think what might else be done by nation state capabilities.

Neil Martin:����

I’ve talked a couple of times during this episode about the good guys versus the bad guys. This is taking it to the real top level. I guess. How important then do you think it is that nations have their own capabilities of being able to defend themselves, and I guess that goes into the kind of training that is happening at ���������¼�. But you know, across Australia, how important is that we have these skilled people that can recognise these types of attacks that might be possible and help kind of protect us against them?��

Sharat Madanapalli:����

Yeah I think maybe Hammond can talk more to it. But security, at least when I was studying, wasn't like a major that I knew much about to specialise in and to go into. It was more like there were these small group of people who were just interested to hack around things and everything. Even I remember in my days, I used to like create a network tunnel between my dorm room and my computer lab so that I could get access to a much faster internet connection, right? And I would call myself a hacker back in the days, so, but then that wasn't taught as much as it's been taught, I think these days, especially at universities like ���������¼�. But I think education and awareness that this is also an important job in the society, just like it is to build programs to make money. It's also important to build systems that safeguard other systems and safeguard sometimes physical sources. I think it's an awareness thing that we can bring about its education.

Hammond Pearce:��

I think to be a really, really highly capable cyber security researcher, attacker, defender, you need to know both the system ins and outs, you know, top to bottom of a computer from everything from assembly to high level languages, and then also be able to use that knowledge in the security context. If you just learn the security on its own. You run the risk that you you don't fully understand what it is you're working on. You know, you might be able to be working in compliance or doing checklists or something like that, if you're on the defending side, where you go, Okay, well, we know we need a firewall, so we'll just make sure we have one, and then we'll tick the box, and we'll install the security company thing, you know, we'll install CrowdStrike, and then all of our problems are solved. Sort of security mindset, which is helpful, but not the complete picture, or even on the attacking side, right? There's a somewhat offensive term, maybe not offensive. There's a somewhat derogatory term for hackers that don't really know what they're doing, called script kiddies, where they're just downloading exploits from the internet and then just following the sort of instructions and be like, okay, you know, I'm going to just hit go, and it's going to break into that remote computer. You know, that's fine, but you don't really know what it is you're doing. You're just following some guide that you found online, and you're trusting the software that you've either purchased or obtained from somewhere to really, you know, be that the top people in the field, you have to know the ins and outs of the system, and you have to know the security mindset as well, and that's both offense and defense. You know, we have a habit in universities in particular, of just teaching defense really well. So, you know, we teach the basics of offense. But I remember there being quite a big hullabaloo when one of the universities in America was like, we're going to make a course on teaching people how to write computer viruses. And everyone went, what? Why would you do that? You'd have all these students that know how to make computer viruses, and they're like, yes, that's the point. We want students who know how to make computer viruses, because then they'll also know how to defend against computer viruses, right? And so that's sort of something that I've been pushing for at ���������¼� as well, not computer viruses in particular, but more offensive focused courses where we teach people not just how to defend things, but how to break into them as well. I'll mention that ���������¼� is, you know, really working quite hard to revamp at cyber security and how we teach it. Same with other universities in Australia, we've just launched a Bachelor of Cyber Security. I know other universities have done that recently, or are planning to do so as well. But of course, you can also just do cyber security as part of your other degree. I'm primarily a computer engineer, so I would hope that people who come in and do normal computer science or software engineering, or computer engineering, or even the other ones, mechatronics engineering, everyone should be thinking about some level of security during their degree, because everyone who interacts with computers has that risk of being attacked at some point or another.

Neil Martin:����

If you could give just one piece of cybersecurity advice that everyone, whether that's individuals or businesses or governments, should follow, what would that piece of advice be?

Hammond Pearce:����

For me, it comes down to just always be suspicious. If you see something on your computer screen, be suspicious of it, because it might not be coming from who you think it is. It might not be coming from the website you think it is. So just always approach anything coming from a computer with that element of doubt in your head to be like, okay, the computer is telling me this. But is it actually true? How can I verify this some other way.

Sharat Madanapalli:����

For me, I think that's that's a very good behavioural trait to have. I'd probably leave the users with a tool, which is the same thing that I've said before. Use a password manager. Just go there. Download something again, not something I'm not interested. Please check up the reviews and all of that, and store your passwords there. That's a good starting point for you not to be hacked, but against phishing and all of that. You need that behavioural trait of being suspicious.

Neil Martin:����
