Symantec reports that an offensive AI agent it called Skynet attacked its AI honeypot and was built to find and recruit other exposed agents into a botnet. The agent was designed to deploy the XMRig cryptominer and steal credentials, with its operating mode authorising up to 100,000 steps without human approval. Symantec says the campaign appears active, and the article does not say how many victims were compromised.
What would have stopped it
Restrict outbound network access and require a human approval step for sensitive agent actions.

“While the primary goal was to deploy a cryptocurrency miner called XMRig, the crooks were also able to steal sensitive data, including login credentials.”
