FakeAgent
campaign · campaign:fakeagent
Malvertising campaign named by Huntress that compromised at least 29 organisations between 2026-07-21 and 2026-07-22. Sponsored search results for the Claude Desktop application linked to a genuine claude.ai URL whose destination was a public user-created artifact on the platform imitating the official download page, viewed roughly 7,100 times before removal, so the ad, the domain and the certificate all presented as legitimate before an onward redirect to attacker infrastructure served the installer. Execution runs through signed-binary side-loading (a repurposed JetBrains Chromium Embedded Framework helper loading a VMProtect-packed trojanised libcef.dll, with a second chain using an IBM SPSS binary and a compiled DirectX shader as its decryption routine) and delivers SectopRAT (Huntress, 2026-07-22; Help Net Security, 2026-07-23; BleepingComputer, 2026-07-23).
