The PowerShell mafia is back! We are giving a Tech Deep Dive session right now where we look at new OST tools to leverage PowerShell for local and remote code execution. PowerShell is not dead for red teams! Available for #OST customers. More info at outflank.nl/ost

Initial access to the max! We just released a new OST tool, using our research and full weaponisation of an obscure file format. This file format allows shellcode loading with just a double click and is under less MotW scrutiny than most other popular initial access vectors. 💪

Excellent blog from Kyle Avery on macOS/linux EDR internals. There are still unanswered questions, so likely more R&D to follow 🧐
