We've written a paper on optimized multi-agent attacks, for which we present a brief writeup in this post. See the paper for more detail. This work was also presented as a spotlight research talk at the MATS Summer 2026 Symposium here. Tl;dr Recent AI cyber-related incidents exposed vulnerable monitoring surfaces to detect attacks stemmed from coordination between multiple AI agents. We show that when several agents distribute the attack fragments so that each trajectory looks benign, a monitor
