Webcast: Shellcode Execution with GoLang

September 28, 2021

In this Black Hills Information Security (BHIS) webcast, we explore using GoLang to author malware with embedded shellcode.

GoLang is a Google-authored modern successor language to C/C++. It is multi-platform, high performance, multi-threaded, and unlike C/C++ includes garbage collection! It has the advantage of compiling to native machine code, unlike .NET C# which is dependent on the common language runtime, and easily reversible. We explore how to execute Windows shellcode with GoLang in the same process thread space, and then also explore one process injection method.

If you are a penetration tester looking to expand your malware authoring skills, a little Go(lang) will take you far!
