Recorded a video demonstration explaining full thread stack spoofing. Video includes Process Hacker for POC. Should be useful for both analysts on hunting suspicious threads and mapped regions in memory, unless of course someone is using Brute Ratel C4 🙂

Ever wanted to make your sketchy sys calls look squeaky clean? I wrote a blog demonstrating a PoC which calls NtOpenProcess to grab a handle to lsass with an arbitrary/spoofed call stack: https://t.co/SWLenJazWW

Since Microsoft plans to disable macros by default, I have decided to release a proof of concept that I use on my engagements by leveraging the document properties built in Microsoft Office.

An relatively easy way to use stack encryption for your implant?
@SolomonSklash‘s SleepyCrypt can easily be used from any language:
https://t.co/IiMHZSLXY5
This for example is how to do it with Nim:
https://t.co/Pjr6MJT8hC
Can also be used for Nim C2 implants as Sleep 🔥😎

I published a tool to #bruteforce the key of @CodeIgniter's session #cookies, in order to sign arbitrary attacker-controlled cookies🍪
I wrote this tool for a use case encountered in #bugbounty recently, but we can find this in #pentest too.

(2/4) Being a DA an adversary can create an evil GPO that will coerce Immediate Scheduled Task execution on the target. The task downloads and executes a PS cradle pointing to the PWNed server. Sure, there’re fancy (py|Sharp)GPOAbuse, etc… But when it’s a pentest, who cares 😒

Undetected from @hackthebox_eu has me following in the steps of a previous attacker. There's an insecure PHP module, reversing a malicious kernel exploit and a backdoored sshd. Lots of Ghidra and understanding the attackers steps and reusing them.
