We've all been there: the trains you're servicing for a customer suddenly brick themselves and the manufacturer claims that's because you've interfered with a security system.

This talk will tell the story of a series of Polish EMUs (Electric Multiple Unit) that all refused to move a few days after arriving at an “unauthorized” service company. We'll go over how a train control system actually works, how we reverse-engineered one and what sort of magical “security” systems we actually found inside of it.

Reality sometimes is stranger than the wildest CTF task. Reality sometimes is running unlock.py on a dozen trains.

Imagine discovering a zero-click attack targeting Apple mobile devices of your colleagues and managing to capture all the stages of the attack. That’s exactly what happened to us! This led to the fixing of four zero-day vulnerabilities and discovering of a previously unknown and highly sophisticated spyware that had been around for years without anyone noticing. We call it Operation Triangulation. We've been teasing this story for almost six months, while thoroughly analyzing every stage of the attack. Now, for the first time, we're ready to tell you all about it. This is the story of the most sophisticated attack chain and spyware ever discovered by Kaspersky.

WebAuthn and FIDO2 promise a great future. Let's see if we can have it today.

When Grace started her job in security and open-source, she didn’t get the joke about honking geese folks in security would throw around and there was never a good time to ask. The same thing is happening for supply chain security. The landscape is evolving rapidly with high adoption but comprehensive documentations and talks, especially for beginners, are still lagging behind. Starting with why we care about supply chain security, the talk will provide an overview of the landscape and how tools like Fulcio, Rekor and cosign come together. Unlike geese, we won’t hiss at you!

This presentation will highlight some of the most exciting and shocking methods by which my team and I routinely let ourselves in on physical jobs.

Many organizations are accustomed to being scared at the results of their network scans and digital penetration tests, but seldom do these tests yield outright "surprise" across an entire enterprise. Some servers are unpatched, some software is vulnerable, and networks are often not properly segmented. No huge shocks there. As head of a Physical Penetration team, however, my deliverable day tends to be quite different. With faces agog, executives routinely watch me describe (or show video) of their doors and cabinets popping open in seconds.
