It's funny how WinDbg's TTD docs[1] emphasizes that PII may appear in dumps, while e.g. docs for crash dump analysis[2] don't.

Based on the observation that behind every warning sign there is a story I suspect that at one point a TTD trace somehow resulted in summoning MS's legal team :)

After 6 successful runs of our Introduction to Linux Kernel Exploitation training—across both public and in-company cohorts—and a 100% positive rating from our students, we are offering it for the first time in English!

This is your opportunity to gain hands-on experience with computer architecture, kernel debugging, the Linux kernel, exploit development, and modern mitigation bypasses alongside an instructor doing top-tier vulnerability research.

Here are a few testimonials from our former students:

"I've always wanted to master the Linux kernel, and this course by Anderson and the Allele Security Intelligence team was the perfect opportunity. It expanded my architecture knowledge, sparked my interest in binary exploitation, and completely exceeded my expectations!"

"An exceptional course on computer architecture and the Linux kernel. The clear structure made complex concepts intuitive, and the practical exercises were game-changing for learning how to identify and exploit kernel vulnerabilities."

What sets our training apart:

Direct support: Personalized contact and guidance starting as soon as you enroll.

Cutting-edge content: Up-to-date curriculum drawn from public sources and our own internal security research.

Expert instruction: Taught by an instructor with over 10 years of world-class vulnerability research experience.

Flexible learning: Class recordings uploaded within 24 hours so you never miss a lesson.

Structured & Accessible: Detailed, beginner-friendly documentation that makes complex concepts easy to follow.

Registration is open! We have a Super Early Bird discount available for the first 4 students.

We also offer corporate group packages. If you have any questions or need assistance with the enrollment process, please let us know—we’re happy to help!

Was going to write a couple of posts here about my weekend experiment but decided to make it a bit more permanent so it can be tested by time. If not, just a bit of random (silly) writing practice before those skills are lost forever.

SAML was created in 2002 by merging four rival XML security protocols into one spec. That design still generates vulnerabilities: a canonicalization flaw via XML comments in 2018, XML round-trip bugs in Go's stdlib in 2020, a GitHub Enterprise SAML auth bypass in 2025, and more.

Matt Schwager breaks down 5 design flaws behind the pattern and makes the case for moving to OIDC.

@hajovonta Welcome to Eastern-Europe! :)

@eloy

When I was at Microsoft, I worked quite closely with some teams at MSRC. They had a lot of concerns like this (relevant to me, memory-safety bugs had been close to 70% of critical vulnerabilities for over a decade, relevant to everyone the absolute number of vulnerabilities had been steadily climbing for 20+ years).

On the 'Decrease the birth rate' axis, I found one piece of framing useful. They differentiated between 'durable' and 'non-durable' mitigations. Durable mitigations render a class of vulnerability non-exploitable. For example, if a short-lived program runs with free turned into a no-op, temporal safety bugs are now non-exploitable. It's not a universally applicable mitigation but it's an easily deployed durable mitigation. In contrast, non-durable defences block specific techniques for exploiting vulnerabilities but don't prevent the vulnerabilities. New exploit techniques eventually bypass non-durable mitigations.

There's a lot of hesitation to deploy non-durable mitigations because they're almost impossible to remove. Even if exploit toolkits come with an automated step to bypass the mitigation, no one wants to be responsible for some large-scale compromise that doesn't include the mitigation bypass and being told that it would have been prevented if the mitigation had remained enabled.

I found this framing useful for reasoning about a lot of things in this space. LLM-based vulnerability discovery remains a non-durable mitigation because it allows closing vulnerabilities but not classes of vulnerability, and it's probabilistic and doesn't find all vulnerabilities of a class. So it motivates attackers to use vulnerability-discovery techniques that find ones LLMs miss.
