Vidar is a name most infostealer trackers know well -- an Arkei descendant that has been snatching browser credentials and crypto wallets since 2018. It usually ships as a .NET binary or a C++ PE. The v1.5 sample we pulled from Triage on May 13, 2026 is neither. It is a 7 MB Go 1.25.4 native PE with a twelve-category sandbox scoring system, dead-drop C2 via Telegram and Steam profile pages, and enough crypto primitives to make a librarian blush.

This analysis focuses on a new variant of Lumma Stealer, a malware that reemerged after a brief hiatus following a law enforcement operation. The article details the malware's code obfuscation, evasion techniques, and persistence mechanisms. It describes Netskope's machine learning-based detection approach, which utilizes a Cloud Sandbox enhanced with ML models to analyze runtime behavior, process trees, and other features. The specific sample analyzed is an NSIS installer file that abuses AutoIt for malicious purposes. The malware employs various anti-analysis techniques and establishes persistence through the Windows Startup folder. Netskope's multi-layered threat protection system successfully detected this Lumma Stealer variant.
