AgentForger proves AI agents can become persistent insider threats

AgentForger is a phishing-based attack that tricks users into creating a rogue AI agent within OpenAI workspaces, giving attackers a persistent insider threat (an automated tool that stays active and follows attacker commands indefinitely). Once activated with a single click, the agent gains full access to apps like Outlook, Slack, and Google Drive, can approve its own actions without asking users, and receives new tasks from attacker-controlled email addresses to steal data, harvest credentials, and launch phishing campaigns.
