Around ~5 years ago I made a video about how SIM cards work, by intercepting the communication between the phone and the SIM.

Did you see my SIM card video and want to learn more about mobile networks? Here is a video I made ~5 years ago introducing the GSM network.

Did you know that the CPU vuln "Zenbleed" 🩸 (CVE-2023-20593) was found through fuzzing? I was able to talk to Tavis Ormandy and learned about his novel approach 🤯 it is so clever!!

Ever wondered how iPhones can be hacked remotely? Watch my latest YouTube video right here on Twitter. My goal with this video is to give you a sense of the insane amount of skill and (engineering) effort that is required to find vulnerabilities in iPhones. At the end of the video, I hope you’ll appreciate the complexity of the task, while realising it’s not simply magic.

A year ago I made a video about the RIDL CPU vulnerability. In case you haven't seen it, here it is uploaded to Twitter directly! The most interesting part of this has been learning about the prior research that later lead to the discovery of these modern side-channel vulnerabilities. I also spend more time explaining "speculative execution" and how these CPU cache timings can be used as a side-channel. If you haven't seen it yet, give it another chance :)
