Here's part 1 of my blog series on hacking the Xbox 360 hypervisor. This covers the design of the hypervisor and hardware security features that back it. Consider it prerequisite material for part 2 which will be released next week (along with the exploit) icode4.coffee/?p=1047

We (me + Igor Kuznetsov) have discovered a new Google Chrome 0-day that is being used in targeted attacks to deliver sophisticated spyware 🔥🔥🔥. It was just fixed as CVE-2025-2783 and we are revealing the first details about it and “Operation ForumTroll” securelist.com/operation-foru…

Someone pointed out that MITRE is letting go of 400+ employees, which is definitely a big number. But with ~9,000 employees total, that’s still less than 5%. To me, that doesn’t explain why the CVE team had to be part of the cut. It’s probably a small group, maybe 5–10 people.

My talk about the recent SMM architecture and security at TheSAS2025 : youtube.com/watch?v=AIGj6Q… The conference was well organized and had plenty of networking opportunities. Though, the best thing was the venue :) It is at a beautiful resort again this year, so you will love it.

Really enjoyed TyphoonCon🌪️ keynote of Andy Andy Nguyen about his journey of hacking gaming consoles. One of the best and most inspiring talks on bug hunting I have ever seen!

Encountered this situation many times this year. As the disrespect for research continues, fewer and fewer reseacher will cooperate with MSRC(Microsoft) in the future.
