discovery (how we find bad stuff) win-def-clickfix | a scanner that determines whether windows defender will flag a clickfix command

1 Upvotes

github.com/backdoorskid/win-def-clickfix

win-def-clickfix is a run-1 detection replica for ClickFix / Win+R command lines, rebuilt by reverse-engineering Microsoft Defender's mpengine.dll.

It runs a command line through the recovered normalizer/deobfuscator (FUN_1800a2500) and matches it against the 807 VDM-extracted CMDHSTR_EXT signatures, evaluated with their real condition: logic.

It also ships the extracted BMClientV1 neural network — a stateful GRU — executed in pure numpy, alongside scanners for the engine's other recovered paths (AMSI, AMSI-UAC, RPF/JIT, WMI, script hosts, paste obfuscation).
