The attack on AI agents that no security tool catches

Here’s something that might change how you see AI security — most defenses are blind to a sneaky attack vector. According to /u/Turbulent-Tap6723, the real threat isn’t the obvious tricks like ignoring instructions. It’s a subtle, multi-message attack that unfolds over time, with each message looking innocent. The AI doesn’t flag anything until it’s too late — by message eight, it’s doing stuff it absolutely shouldn’t. That’s because most security tools evaluate messages one at a time — they don’t remember what came before. But here’s where it gets interesting: Bendex Arc, a new tool, tracks session behavior across multiple interactions, catching these creeping threats. ((slower)) As /u/Turbulent-Tap6723 points out, no security tool on the market really handles this yet. So, if you’re building or deploying AI agents, the key takeaway is: your defenses need to see the whole conversation, not just isolated messages. The future of AI security depends on catching these long game attacks early.
