BHIS PODCAST: Endpoint Security Got You Down? No PowerShell? No Problem.

What this episode covers

Do your PowerShell scripts keep getting caught? Tired of dealing with EDRs & Windows Defender every time you need to pop a box? In this one-hour podcast, originally recorded as a live webcast, we introduce a somewhat new Red Team approach that we call BYOI (Bring Your Own Interpreter). Turns out, by harnessing the powah of C# and the .NET framework you can embed entire interpreters inside of a C# binary. This allows you to dynamically access all of the .NET API from a scripting language of your choosing without going through Powershell in any way! We also cover some basic .NET & C# concepts in order to understand why this is possible and all the hype surrounding offensive C# tradecraft. Additionally, we demo SILENTTRINITY, a post-exploitation tool we have developed that attempts to weaponize the BYOI concept *AND* dropped a pretty huge update for it live during the webcast! This podcast was originally recorded on 2/14/2019 as a live webcast with our very own Marcello Salvati.
