Today I’m sharing a blog post on the implementation of kernel mode shadow stacks on Windows! This post covers actively debugging the Secure Kernel and also outlines why VTL 1 is relied on to help maintain the integrity of the supervisor shadow stacks! connormcgarr.github.io/km-sh…

New year, I'm officially open for new opportunities. If you need a guy focused on (Windows platforms) advanced vulnerability research and (zero-day) exploit detection, please let me know. :) #OpenToWork

Over the past year, we have made significant progress in leveraging GPT for vulnerability detection,
including integrating it with static engines (dl.acm.org/doi/pdf/10.1145/3…), combining RAG with formal verification (arxiv.org/pdf/2405.02580),
and employing RAG for GPT vulnerability detection (arxiv.org/pdf/2401.16185).
The common core of these efforts is to determine how much knowledge we can learn from past audit reports, attack events, expert experience, and all smart contracts, as well as the type and structure of that knowledge. The amount of knowledge directly affects the final outcome, making this a task where greater effort yields greater results.
Of course, there is also an ultimate solution (github.com/BradMoonUESTC/tri…).
These tools have earned me a over of $50,000 in bounties over the past year and a half, without to audit anything, only vulnerability confirmation is required, which also causes me to feel that my manual auditing capabilities have deteriorated a lot....

I've released a couple of tools for reversing Qualcomm basebands, including a script to decompress CLADE sections on the latest firmware binaries. To my knowledge, there is no public code that can do this. Enjoy! github.com/mzakocs/qualcomm_…

Got my first two Amazon book reviews!
I can’t even describe how great it feels to read feedback from people who appreciate the level of detail and enjoy reading it.
Assembly isn’t an easy topics to learn, and I hope my book makes the learning process less intimidating :)

This bug has renewed my faith in fuzzers. It was my pleasure to assist and RCA this.
At some point last fall/winter I felt like giving up on everything. I don’t know where i got the energy to keep going, but def one place was my work.
Today, that work officially paid off:

Fuzzer will be open sourced soon :)

Woot!!! Very excited about this one! Announcing OpenAI’s Bug Bounty Program openai.com/blog/bug-bounty-p…
First day I was able to make it out of bed without hurting in months
To everyone who is suffering from chronic illnesses, depression or pain, love you and appreciate you.

omg, I have langchain up and running, reading my own documents, and using them in conjunction with calls to openai.
And I did this without a third-party platform. I just read the docs, followed a couple of blog posts, and cussed a lot. Old-school.
Yay me.

One of the benefits of AI-powered software based around Context and Questions will be an extraordinary increase in transparency.
Many of the complex processes that were a pic to us before will become visible for the first time.

Excited for this new chapter in my life and for the opportunity to serve all Canadians in these, and future, challenging times. I'm proud to be a small variable in a very large equation, hoping to make a change.
Today, CSE welcomes @aionescu as Technical Director, Platform Operations and Research. Alex's world-class operating system expertise will help advance CSE's cyber security interests both at home and abroad, and promote cyber-safe practices for all Canadians. Welcome Alex!
Pretty interesting stuff I’m going to have to dig in on this one I missed, feels like memory lane.
Well, that's exciting, "Wearing Many Hats: the Rise of the Professional Security Hacker" is no longer vaporware or alpha but now out as a dedicated @datasociety report, covering the history of hackers going pro datasociety.net/library/wear…

💪 I fully support @noUpside in all of this. I’ve been watching her work for years now, have had her on the show, and have seen nothing but integrity and quality from her.
This behavior from Shellenberger is reprehensible.
People say a lot of crazy things on the internet; I usually ignore it. But today, after nearly a full month of being smeared by Michael Shellenberger, including in sworn Congressional testimony, I’m releasing some files of my own.
