Vidar Stealer Unmasked: Code Signing Abuse, Go Loaders and File Inflation
Unit 42 dissects a Vidar Stealer campaign that chains code-signing abuse, Go-compiled DLL sideloading, and file inflation to bypass endpoint defences — a commodity threat adopting APT-grade evasion.
Summary written by editorial AI · Source link below
A cybercrime campaign combined a loader-as-a-service framework and DLL sideloading via a Go-compiled fake MpClient.dll, a novel evasion layer combination. The post Vidar Stealer Unmasked: Code Signing Abuse, Go Loaders and File Inflation appeared first on Unit 42 .
Editorial Analysis
When commodity info-stealers adopt evasion techniques previously reserved for APTs — code-signing abuse, compiled-language loaders, file inflation — the baseline detection challenge rises for all defenders.
Update endpoint detection rules for Go-binary DLL sideloading and file-inflation patterns, and verify code-signing validation in your security stack.
Commodity malware is adopting nation-state-grade evasion techniques, requiring enterprises to upgrade detection capabilities.
