One runaway AI agent racked up a $50,000 cloud bill

Mandiant's AI Risk and Resilience report details prompt injection, AI supply chain compromises, agent abuse, and a runaway agent that accrued $50,000 in cloud charges.

Mandiant, drawing on Google Threat Intelligence Group (GTIG) observations, warns that poisoned data sources, model dependencies, and extension hooks can turn AI agents into channels for reconnaissance, lateral movement, and sandbox escape. Mandiant responded to incidents involving UNC6780 (TeamPCP), who stole AI service credentials and used prompt injection against AI coding assistants, while GTIG disclosed the first confirmed criminal use of an AI-developed zero-day exploit in a planned mass exploitation campaign. Red team tests showed an AI assistant manipulated into cloning internal repositories to an external GitHub account, and a runaway accounting agent made over 15,000 costly API calls in under an hour, generating roughly $50,000 in cloud charges.

Hackers Can Rent VectraRAT for $250 a Month to Take Control of Windows PCs

SOCRadar uncovered VectraRAT, a previously undocumented $250-per-month Windows RAT rental service delivered via Amadey and ClickFix lures.

SOCRadar's Threat Research Unit identified VectraRAT, a rental-only remote access trojan sold by a developer known as Vectra (formerly Nyxel), after an exposed online directory revealed samples, licenses, and operator logs across ten-plus servers. The toolkit includes a Linux control server, Windows implant, payload builder, and VectraHub panel, enabling hidden desktop access, keylogging, command execution, credential theft, file transfer, proxying, and silent privilege escalation. Of victims with OS data, 48 percent ran corporate Windows editions, and researchers recorded 38 genuine victim sessions in under a week, including file theft from business systems. Distribution occurs through the Amadey loader and ClickFix pages impersonating TurboTax, with custom TCP-based C2 over non-standard ports.
