The OWASP Top 10 2021 is out. I'm excited the SSRF is on the list and would like to thank @vanderaj for giving me the chance to contribute to writing the section of SSRF! #owasp owasp.org/Top10/

Jackson is one of the most brilliant infosec practitioners I’ve ever met. His content here is brilliant and informed by his years of deep experience. This is the high signal content you’re looking for.

It's finally ready: Prodfiler, a continuous profiler that "just works" -- for C/C++/Rust/Go/JVM/Python/Perl/PHP -- no code change required, no symbols on the machine required, no service restart required. Check out: prodfiler.com or the blog post below.

The more I look at the Green Lambert OS X sample, the more I appreciate Hopper Disassembler and the fact it’s only $99. Great work, @bSr43!
Today I learned that unconstrained delegation trumps gMSA protection against interactive logons on systems the gMSA isn't installed on. Makes sense - a ticket is a ticket, and no interactive logon is taking place here. Screenshots tell the tale Thanks @harmj0y for the help
I am honored to win the Best Server-Side Bug of @PwnieAwards 2021 again. Thanks everyone, I will keep rocking and Hack the Planet!!
#remotepotato0 xsession is finally out! @splinter_code and me released it: github.com/antonioCoco/Re… Coerce and relay NTLM auth from any user in any session w/o session 0! Enjoy responsibly ;)
I really enjoyed being able to throw my #infosec knowledge around in this fascinating dive into IT/OT systems & burnout. With so much ransomware around it's nice to remember @MalwareTechBlog's nice work on WannaCry

It looks like Microsoft finally fixed all my Exchange vulnerabilities (including Pwn2Own bugs) ! Here is a small spoiler - You can't imagine how amazing it is when I found Exchange still suffered from Padding Oracle Attack 😻 - blackhat.com/us-21/briefing… #BHUSA #DEFCON
Sometimes instead of blogging I feel like making a big old Twitter thread, so let's talk about Cobalt Strike for people only vaguely familiar (or misinformed) with the concept. Maybe I'll blog it later.
A massive bug, affecting all recent versions of macOS was actively exploited as an 0day by malware 👾🍎 Read our blog post, #100 "All Your Macs Are Belong To Us" objective-see.com/blog/blog_0x64…

The most frustrating thing I hear on debrief calls: "So, you're saying if we had just blocked X, then you never would have gotten this far, correct?" I get it, but the answer is always "no". Better question: "Had we blocked this, what would you have done next?"
