Vidar v1.5 in Go: same family, new language, heavy sandbox checks
released on 2026-05-18 @ 07:03:17 PM
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.
