Buhtrap RAT Resurfaces in New Campaign Targeting Russian Accountants via Search Ads

Specialists from F6 have identified a fresh distribution campaign for the Buhtrap RAT remote access trojan. Attackers continue to lure accountants and lawyers to counterfeit professional websites promoted through search engine advertisements. The latest lure mimics the legitimate resource Glavnaya Kniga Bukhgaltera, where visitors seeking documents instead receive a ZIP archive containing malicious payload delivered through JavaScript interception. The infection chain remains largely unchanged from prior operations, with the primary update being refreshed command-and-control infrastructure. Buhtrap has operated since 2014 as both malware and an associated criminal group; its source code leak in 2016 enabled wider adoption by financially motivated actors. Identified decoy domains include glavaudit.org, buhotchet.com, and audit24.org. Users are advised to verify site addresses carefully and avoid executing disguised EXE files.
