The paper tested MESA across three multi-agent scenarios, eight network topologies, and five open-source language models from the Qwen, Llama, and Gemma families. The core finding: attack impact is not spread evenly. A single edge can account for up to 75% of total attack success, which means random defensive coverage wastes most of its budget. MESA uses six graph-based metrics and two dynamic probes — no prior attack data required — and its rankings correlated with real per-edge attack success at a mean Spearman rank of +0.60.\n\nThe practical payoff is notable: monitoring the top 10% of MESA-ranked edges intercepted roughly three times as many successful attacks as random allocation of the same resources. That kind of leverage matters because multi-agent systems are proliferating fast — LangGraph, AutoGen, and similar orchestration tools are becoming standard plumbing for enterprise AI workflows, and most of their inter-agent channels are trusted by default.\n\nSecurity research on multi-agent systems is still catching up to adoption. Most existing defenses focus on individual model inputs, not the channels between agents — the same blind spot that made early microservices architectures easy to pivot through once an attacker got inside the perimeter.","[\"ai\",\"security\",\"multi-agent systems\",\"llm\"]","2026-06-30T04:00:00.000Z","2026-06-30T12:55:19.050Z","2026-06-30T12:55:21.984Z","published",null,[],"security",[26,24,27,28],"ai","multi-agent systems","llm",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.30602",0,{"sections":35},[36,40,44,49,54,59,64,69,74,79,84,88,93,98],{"name":37,"slug":26,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":24,"count":42,"latest_published_at":43},"Security",294,"2026-07-15T19:59:48.000Z",{"name":45,"slug":46,"count":47,"latest_published_at":48},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":63},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":65,"slug":66,"count":67,"latest_published_at":68},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":70,"slug":71,"count":72,"latest_published_at":73},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":75,"slug":76,"count":77,"latest_published_at":78},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":80,"slug":81,"count":82,"latest_published_at":83},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":85,"slug":86,"count":82,"latest_published_at":87},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
