Team46 is a sophisticated APT group active since at least late 2024, targeting Russian government, academic, and media organizations through spearphishing emails disguised as forum invitations or service notifications. They exploit zero-day vulnerabilities like CVE-2025-2783 in Google Chrome (March 2025, Operation ForumTroll) and CVE-2024-6473 in Yandex Browser, deploying multi-stage loaders (e.g., winsta.dll, donut shellcode) that decrypt payloads using machine-specific keys like firmware UUID for environmental guardrails. Key malware includes the Trinper backdoor for keylogging, clipboard theft, file/process discovery, and encrypted C2 exfiltration over HTTPS with domain fronting, alongside auxiliary .NET tools (dirlist.exe, ProcessList.exe) and variants using Cobalt Strike or Dante backdoor; the group employs obfuscation, AMSI bypasses, debugger evasion, and self-deletion for persistence and stealth. Positive Technologies attributes TaxOff operations to Team46 based on identical PowerShell patterns, loaders, and hyphenated CDN-mimicking infrastructure (e.g., ms-appdata-*.global.ssl.fastly.net).
