Smashing Security podcast #472: AI gets hacked, and BitLocker gets bypassed

What if your AI coding assistant could be tricked into stealing your own company's secrets - by reading a single booby-trapped bug report? No phishing email. No malware. No password ever stolen. Just an AI doing exactly what it was told. Meanwhile, someone themselves Nightmare Eclipse has decided to teach Microsoft a lesson. The result? Three zero-days dropped on the internet, one of which lets a thief with a USB stick walk straight past BitLocker. Microsoft is furious. Plus don't miss our featured interview with Son Nguyen Kim of Proton Pass, who explains why plugging AI agents into your email and calendar without thinking twice is rather like hiring a new employee with the keys to everything - and skipping the background check. All this and more in episode 472 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest Paul Ducklin.

Smashing Security podcast #471: This AI worm just rewrote its own rules

Researchers at the University of Toronto have built a worm that thinks for itself. Using free off-the-shelf AI models it works out how to break into each new computer it encounters, and hijacks the powerful ones to host its own AI brain. And then the researchers discovered their creation had quietly removed the list of machines it wasn't supposed to attack. Meanwhile, Meta's shiny new AI customer support agent has been cheerfully helping hackers help themselves to other people's Instagram accounts. Just keep asking, politely but firmly, to have a password reset sent to a different email address - and the AI will eventually agree. All this and more in episode 471 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest James Ball.

Smashing Security podcast #470: This AI security flaw might be impossible to fix

A website called "UK visa portal" has been quietly collecting passport scans, selfies, and personal data from thousands of travellers who thought they were applying through official channels. They weren't. And when a journalist tried to warn the company, it was lawyers who responded. Meanwhile, a paper from Cornell suggests that prompt injection - the technique malicious actors use to trick AI agents into doing things they really shouldn't - may be fundamentally unsolvable. Which is err... awkward, because everyone is rushing to plug AI agents into their email, files, and corporate networks. Plus don't miss our featured interview with Andrea Sivieri of CoreView, who tells us how hackers can lock your entire organisation out of its Microsoft 365 environment... without having to trick you into running a single piece of malicious code or handing over a password. All this and more in episode 470 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest Tanya Janca.

Smashing Security podcast #469: What your Oura ring won’t tell you

CISA, the US government agency whose entire job is keeping America's critical infrastructure safe from hackers, has had a contractor publish dozens of plain-text credentials to a public GitHub profile. Meanwhile, your Oura ring is quietly transmitting some of its data unencrypted - and when one journalist asked the company how often it hands user data to law enforcement, the answer was quite telling. Plus don't miss our featured interview with OPSWAT's Benny Czarny about his new book "Cybersecurity Upside Down." All this and more in episode 469 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest Lesley Carhart.

Smashing Security podcast #468: High-speed train hacks and homicidal lawnmowers

A 23-year-old radio enthusiast spent £300 on a piece of kit from the internet, and used it to bring four packed high-speed trains to a screeching halt. His defence in court? Possibly the most creative excuse we've heard all year. Meanwhile, owners of $4,000 robot lawnmowers are discovering that their gadget can be hijacked over the internet, redirected at journalists who foolishly lie down in front of it, and used to harvest Wi-Fi passwords, email addresses, and GPS coordinates. Change the default password? Sure - until the next firmware update silently resets it back. Plus - don't miss our featured interview with XBOW's Brendan Dolan-Gavitt about how AI is transforming penetration testing. All this and more in episode 468 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest Geoff White.

Smashing Security podcast #467: How ShinyHunters hacked the world’s biggest universities

Welcome to the largest educational data breach in history - affecting nearly 9,000 institutions, every Ivy League university, and 30 million students mid-finals. When Canvas's parent company refused to pay and announced they had deployed "security patches" instead, the hackers were less than impressed. So they came back through the cat flap. Meanwhile, a famous finance expert's face has been showing up on Facebook adverts promising hot stock tips and exclusive WhatsApp investment groups. Spoiler: it isn't him, the tips aren't real, and you're about to be scammed. Plus we chat to Mike Nichols of Elastic, about how the SOC isn't dying, attackers and defenders are both deploying AI agents, and how the real security crisis is no longer human users - it's the bots acting on their behalf. All this and more in episode 467 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest Danny Palmer.

Smashing Security podcast #466: Meta sees everything, Copy Fail, and a deepfake gets hired

Meta's smart glasses promise privacy "designed for you" - but everything they record was being beamed off to workers in Nairobi to label by hand. When those workers blew the whistle, Meta sacked all 1,108 of them. Meanwhile, the IT press is in a frenzy over a new Linux bug called "Copy Fail" - complete with logo, dedicated website, and a marketing-friendly name. But is it really the disaster everyone's making it out to be? And in our featured interview, Jake Moore of ESET explains how he tricked a company into offering his deepfake clone a job - after a perfectly normal-looking video interview. All this and more in episode 466 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, joined this week by special guest Paul Ducklin.

Smashing Security podcast #465: This developer wanted to cheat at Roblox. It cost millions

A developer at an AI startup wanted to cheat at Roblox. They downloaded a dodgy script on their work laptop. That one decision triggered a cascade of failures that ended with a $2 million data breach affecting hundreds of thousands of organisations. All for some free in-game currency. Meanwhile, there's a 1980s phone protocol called SS7 that lets shadowy surveillance companies track anyone, anywhere, via their mobile phone. Governments know about it. Telecoms know about it. Nobody's fixing it. All this and more in episode 465 of the "Smashing Security" podcast with cybersecurity keynote speaker and industry veteran Graham Cluley, joined this week by special guest James Ball. Plus! Don't miss our featured interview with Rob Edmondson of CoreView, discussing how to lock down Microsoft 365 before it's too late.

Smashing Security podcast #464: Rockstar got hacked. The data was junk. The secrets it revealed were not

A company that ran anonymous tip lines for 35,000 American schools - handling reports of bullying, weapons, and self-harm - boasted on its website that it had suffered zero security breaches in over 20 years. A hacker called Internet Yiff Machine thought that sounded like a challenge, with predictable results... Meanwhile, Rockstar Games gets hacked again - and the stolen data turns out to be less embarrassing than the financial secrets it accidentally revealed. GTA Online is still making half a billion dollars a year. Red Dead Redemption is not. All this and more in episode 464 of the "Smashing Security" podcast with cybersecurity keynote speaker and industry veteran Graham Cluley, joined this week by special guest BBC cybersecurity correspondent Joe Tidy. Plus! Don't miss our featured interview with Ryan Benson of Meter.

Smashing Security podcast #463: This AI company leaked its own code. It’s also built something terrifying

A hacking group claims to have broken into the flood defence system protecting Venice's Piazza San Marco - and is offering to sell access to whoever wants it. The asking price? A frankly insulting $600. Meanwhile, Anthropic accidentally leaked the source code for Claude Code via a basic packaging mistake. Oh, and by the way, they've also just revealed they've built an AI model called Mythos that can find and chain together software vulnerabilities faster than any human. Sleep well. All this and more in episode 463 of the “Smashing Security” podcast with cybersecurity expert and keynote speaker Graham Cluley, joined this week by special guest Tanya Janca.

Smashing Security podcast #462: LinkedIn is spying on you, and you agreed to nothing

LinkedIn has been secretly scanning your browser for over 6,000 installed extensions — on every single click you make. It can tell if you're job hunting, what religion you are, and whether you have ADHD. And none of this is mentioned anywhere in their privacy policy. Meanwhile, California's crypto millionaires are learning that no amount of encryption can protect you from someone who knocks on your door pretending to deliver a pizza. All this and more in episode 462 of the “Smashing Security” podcast with cybersecurity expert and keynote speaker Graham Cluley, joined this week by special guest Dave Bittner.

Smashing Security podcast #461: This man hid $400 million in a fishing rod. Then it vanished

A cannabis-growing, beekeeping, gyrocopter-flying Irishman invested his drug money in Bitcoin back in 2011 - and now sits on a fortune worth $400 million. There's just one small problem: the access codes were tucked inside his fishing rod case, which has mysteriously vanished. Or has it? Because this week, one of his frozen wallets suddenly woke up and moved $35 million - and someone had to identify themselves to do it. Meanwhile, Ajax Football Club scores a spectacular cyber own-goal, as a data breach that the club claimed affected "a few hundred" fans turns out to may have exposed the personal details of 300,000 supporters - along with the ability to steal match tickets and quietly remove people from the stadium ban list. All this and more in episode 461 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, joined this week by special guest Danny Palmer.

Smashing Security podcast #460: Never knock on the door of a nuclear submarine base and ask for a selfie

A disgruntled data analyst decides that the best response to losing his contract is to steal the entire company payroll database and demand $2.5 million in Bitcoin - signing his extortion emails from a company called "Loot." Meanwhile, two people drive up to the entrance of the UK's nuclear submarine base at Faslane and politely ask if they can have a look around. Tourists? Spies? Something in between? All this and more in episode 460 of the "Smashing Security" podcast with cybersecurity veteran Graham Cluley, and special guest Jenny Radcliffe.

In episode 459 of Smashing Security, we dive into a chillingly clever account takeover attempt targeting WordPress co-founder Matt Mullenweg - involving MFA fatigue, real Apple alerts, a convincing support call, and a phishing page that oh-so-nearly worked. If a famous techie could have this happen to you, can you be sure you're immune? Plus: would you donate your lifetime medical history to science if you were promised anonymity? We unpack serious concerns around UK Biobank, where “de-identified” data may not be as anonymous as you think — and how surprisingly little information it takes to reveal everything. And! Human-powered “AI”, and a punishment worse than prison: eight hours on the RSA expo floor... All this, and much more, in episode 459 of the "Smashing Security" podcast with cybersecurity veteran Graham Cluley, and special guest Paul Ducklin.

Free parking in Russia after Distributed Denial-of-Service attack knocks city’s parking system offline

Drivers in the Russian city of Perm have been enjoying an unexpected bonus this week: free parking. Not because the city council suddenly decided to embrace generosity - but rather because hackers succeeded in knocking the city's payment system offline.

Smashing Security podcast #458: How not to steal $46 million from the US government

A Wikipedia security engineer accidentally wakes a dormant JavaScript worm that hadn't stirred since 2024 - and within minutes, giant woodpecker images are plastered across the internet's favourite encyclopaedia. Meanwhile, a crypto contractor hired to help the US Marshals manage seized digital assets allegedly decides to help himself to $46 million of it - and then brags about it on a recorded Telegram call. Plus: Graham champions Asterix, Trisha discovers the fantasy novels of Robin Hobb, and someone called "Lick" ends up in the nick.
