Background
Houdini is a VBS-based RAT that traces back to 2013. Originally it was packaged inside an .exe, but from 2018 onward it was spread through spam or pulled in by other malware directly as a .vbs file. In 2019 a JavaScript reimplementation of Houdini surfaced as WSHRAT, rewritten under the name Kognito.
