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.

StepDrainer is a Malware-as-a-Service (MaaS) platform engineered to steal digital assets from cryptocurrency wallets, including fungible tokens and high-value NFT collections. The malware supports more than 20 blockchain networks and incorporates multiple draining techniques, particularly abusing ERC-20 token permissions and NFT approval mechanisms. The platform includes automated asset transfer capabilities, compatibility with widely used mobile wallets, and encrypted logging via Telegram channels for attacker monitoring. StepDrainer is commercially distributed within cybercriminal ecosystems, with pricing models ranging from approximately $750 for full source code access to $150 for a shared version that imposes a 20% commission on successful thefts.
