PowerShell for Hackers

June 23, 2019 @ 9:00 am 5:00 pm


PowerShell has evolved greatly in the last decade to become the tool of choice for Windows Post-Exploitation by many (see IBM on PS Attacks peaking at 57%). Indeed, with great power(shell) comes great responsibility. PowerShell has come a long way, and is the main enabler of Microsoft’s management efforts & future, both on premise and in the cloud. Yet in the “living of the land” reality, where any admin tool can be used as an attack tool, PowerShell is “part of the OS” and helps us do anything we want without any pre-reqs – we’ll see how to run fileless in memory without touching disk/without launching explicit process/without powershell.exe/obfuscating command and much more. While MS has some cool detection & logging techniques, we will demonstrate how Powershell blue team techniques can be bypassed in creative ways (from standard stuff to advanced).
