‘Ghostjacking’ Attack Uses Poisoned Logs to Turn AI Agents Bad
DEF CON – Tenet security researchers have demonstrated a novel AI hijacking attack that relies on tools trusted by the agent to deliver malicious instructions.
The Israeli cybersecurity startup, which emerged from stealth mode in June to protect organizations from rogue agents, previously demonstrated how threat actors can poison data fed to AI agents to manipulate their behavior, an action it calls ‘Agentjacking’.
