Attackers hijack at least 17 internet-exposed Cairn AI pentesting panels, making the agents plant SSH keys and a Poseidon implant on their own hosts and hunt AI API keys
NorForge, an AI-agent sandboxing firm, reported on Oct 27 that by passively watching internet-exposed panels of Cairn, a platform where users give AI agents a goal and they work autonomously, it saw attackers inject tasks into at least 17 panels that lacked authentication. Activity intensified around Oct 20, with possible reconnaissance from about Oct 10. Injected tasks had the agents add attacker SSH keys to the kali user's authorized_keys, enumerate environment variables and config files for secrets such as ANTHROPIC_AUTH_TOKEN and write them where any panel visitor could read them; on Oct 21 at 21:15 UTC one task carried a base64 script that the agent decoded and ran, downloading and launching a Poseidon implant (Mythic framework) that communicated via Bunny.net infrastructure. Synchronized waves across panels suggest scripting, with apparent human intervention before malware deployment. Some probed for container escapes; NorForge could not tell whether any succeeded. The volume of data actually taken is not confirmed. A separate handle, AstraRCE, defaced many panels on Oct 20.
Damage
Persistence, malware and credential theft (including AI API keys) on hosts running exposed AI attack agents

GBHackers, Oct 27 12:39 UTC (NorForge research), second source. Evidence confidence: medium. NorForge's own report was not located/opened; facts rest on two security-news write-ups of it. Related to cairn-agents-100-company-sites (Cairn used offensively) but distinct: here the agents' own panels were hijacked. Autonomy 2: agents executed injected tasks within their task loop. Novelty 3: first documented campaign turning exposed AI attack-agent panels against their own hosts. Victims are unnamed, so no victims rows.
Factor ratings and the score are this index’s judgments by a published formula; facts, dates and figures come from the linked sources. Where a lawsuit is pending, the summary reports allegations, not findings.
