The Hacker News and Security Affairs both describe an AI-agent campaign attributed to a group called CyberXero.
Evidence: Independent reports. Security stories run only with a named disclosure or independent reporting behind them.
Two security publications reported on October 12 that a group called CyberXero used AI agents in a campaign that stole data on Ukrainians. The Hacker News reported that CyberXero used Anthropic's Claude Code in a campaign that took more than 628,000 Ukrainian records. Security Affairs, covering the same incident, reported that the group used 51 AI agents to steal 628,000 Ukrainian records. The two reports agree on the scale of the theft and on the use of AI agents to carry it out. The material supplied for this edition does not identify who first discovered and documented the campaign. It also does not say which Ukrainian organizations or individuals were affected, what kinds of records were taken, or whether Anthropic has responded. The case adds to a growing number of reported intrusions in which attackers used AI coding agents to run several operations at once. That trend matters to defenders because it can let a small group carry out work that once took a larger team. Organizations holding data on Ukrainian citizens should watch for further technical details and indicators of compromise as they are published.
