When most people think about AI security, they imagine technical attacks. But one of the most effective attacks against AI agents looks surprisingly familiar: Social engineering. Humans have spent decades learning to recognize: • phishing • impersonation • manipulation • suspicious requests AI agents haven't. An agent doesn't need malware to fail. Sometimes all it takes is a convincing instruction. That's what makes prompt injection so interesting. The attack often isn't exploiting software. It's exploiting trust. A manipulated instruction can cause an agent to: • ignore safeguards • reveal information • change behavior • execute unintended actions And because the instruction looks legitimate, traditional security controls may never notice. As AI agents gain: • memory • tool access • autonomy • workflow control ...the cost of misplaced trust increases.…
