Here is a first draft on an NTLM relay mindmap 🙂 from authentication coercion to post-relay exploitation. I'll gladly update/correct it if you think there are things wrong or missing. ➡️Featured on The Hacker Recipes thehacker.recipes/ad-ds/movement…

[BLOG] Ok, I've written about my experience of battling with both managed and unmanaged memory allocations to try and improve @FuzzySec's Melkor POC. rastamouse.me/building-a-sli…

@domchell 💯 I thought of doing a blog post showing ways to minimise or clear heap memory allocations in your C# tooling, kinda like programming OPSEC tips that don’t rely of the GC. Not sure how useful it would be though.

SUCH a good read. I love the section where they explicitly explain the process used to write custom shellcode for OpenBSD. Even for a noob to Binary Exploitation that was so easy to follow and really emboldening to go after these sort of bugs. Bravo! blog.assetnote.io/2023/08/09/exp…

Excited to share my new research: a POC of a new “threadless” process injection technique that works by utilizing the concept of DLL Notification Callbacks in local/remote processes. github.com/ShorSec/DllNot… An accompanying blog post with more details: shorsec.io/blog/dll-notif…

. @samwcyo's write ups not only contain a 👌 amount of technical details, but also tell a story and describe the mentality required to find these internet breaking bugs. Also, note the verbiage surrounding "interesting" or "curious". Essential. Must read: samcurry.net/points-com/

Me and @Her0_IT did a fair bit of research against one of the leading EDRs in the sector. This first post will hopefully be the start of a long saga, documenting all of our findings. This first part was dated back in 2020: riccardoancarani.github.io/2023-08-03-att…
