one of the reasons i don’t play CTF is that I hate when I try to solve a reverse engineering challenges for fun and I find that 98% of the challenge is a cryptography :) like why ? I will go spend more time reversing some “real” shit and find real bugs lol
New blog post: Laptop froze on hibernate, because an Intel driver bailed during power transition and left a power IRP hanging. This can be an interesting one for those that are interested in how I maneuver through a crash dump and how I think, etc. medium.com/@Debugger/hibe…
I've been researching the Microsoft cloud for almost 7 years now. A few months ago that research resulted in the most impactful vulnerability I will probably ever find: a token validation flaw allowing me to get Global Admin in any Entra ID tenant. Blog: dirkjanm.io/obtaining-glob…

Please join me on the next @offby1security stream with guest Eugene Lim (@spaceraccoonsec ) on 4-Sept at 6PM PT for a session on "0-day Hunting Strategy!" This will be a great session for those interested in vulnerability research! Note the time at 6PM PT youtube.com/watch?v=dMt2qy…
As a little follow up, I wrote a small blog post/tutorial on how to reverse engineer windows drivers with IDA - this is aimed at people that newer touched drivers before and covers IOCTL codes, IRPs and some IDA shenanigans with unions. eversinc33.com/posts/driver-r… Enjoy :3
Our latest post details how we exploited Retbleed (a CPU vulnerability) to compromise a machine from a sandboxed process and VM! Curious? 👇 bughunters.google.com/blog/624373010…
New class: Hypervisor Field Updates 2021-2025 In this series of four lectures @alisaesage looks into recent virtualization technology developments across hardware, exploit competitions, emergent attacks and fuzzing research. Details and purchase here: zerodayengineering.com/training/maste…
Ring 0 is a highly-privileged state on CPUs. Negative Ring Levels have even *higher* privilege. You just haven’t heard of them. For X86, Ring -1 is Hardware Virtualization, Ring -2 is System Management Mode, Ring -3 is Intel ME / AMD PSP. Arm get's even weirder:
10+ hours of trying to write lsass parser end with fail :)

I hope to get discipline for reading it, because this year i have a skillissue managing my time and finishing things that i had started :)
Finalizing a series of lectures updating my Hypervisor Vulnerability Research course on the period 2021-2025 MASSIVE new developments across virtualization hardware technology, hypervisor fuzzing, emergent attacks, and exploit competitions 🔥 @zerodaytraining
The 12th Annual Flare-On Challenge kicks off Sept 26 at 8PM EST! Reverse engineering pros, from Windows to Web3 (with a YARA twist), it's your time to shine. 🏆 Get ready → bit.ly/4ofb5g8 #FlareOn12
You can import APIs into IAT dynamically at runtime, i just called VirtualAlloc without calling VirtualAlloc in my code maybe it's not something cool but you can use this approach to avoid IAT Hooks etc
