Don't worry, it hasn't gone to my head just yet. A fair few of the slides are dedicated to slagging off the billionaire bosses of AI firms...

Delighted to be giving the keynote at the Richmond Cybersecurity Forum in Davos today. The subject? How AI has changed cybersecurity, and how AI could be the biggest insider threat your firm has ever faced. And no, there isn't any snow this time of year. Even AI can't make that happen.

If, like me, you were a teenage boy in the mid-1980s you quite possibly remember Kelly LeBrock in the movie "Weird Science"... How could we resist getting into computers after that!? Anyway, this and much more discussed in episode 485 of "Smashing Security" podcast with special guest Lianne Potter

Plus - ever had your Bluetooth headphones refuse to switch over to your phone... because of a browser tab? One guy found a single AliExpress webpage, playing *nothing* at zero volume. Somehow his headphones could still "hear" it. This is audio fingerprinting - a sneaky tracking trick.

In the latest "Smashing Security" podcast, "Five Eyes" intelligence agencies (not Five Guys 🍔) have published fresh advice on how firms should talk to the public after a breach. Their message in short? "please, for the love of God, stop calling every hack 'sophisticated'"

On the latest episode of the "Smashing Security" podcast I was joined by @jamesrball.com who took a step back from the stories of AI "going rogue" and and asked the awkward question: is this really an emergent AI apocalypse, or were AI firms just lousy at security?

Scattered Spider members who hacked TfL from their bedroom, costing £39 million and exposing data on 10 million customers, were sentenced to 5 years and 6 months each today. The NCA had video footage of them doing it. Video footage they had taken themselves! Remember - crime doesn't pay.

French police have arrested a 21-year-old known as "HexDex". He's suspected of around 100 data breaches in just a few months, including the French Ministry of National Education, and the national firearms registry. Approx four breaches a week. MFA and patching still matters! 1/2

A wanted fugitive hides in a kitchen cabinet while police search the house around him - and decides to post about his whereabouts on Snapchat. Twice. 🤦 The lesson? If you don't want people to know where you are, don't post it on social media. Seems obvious, but apparently not to everyone...
