  "account": "Cisco has made a behavior detection engine open source, named Project Quarry. The tool aims to help security teams prevent rogue AI agents from being exploited, similar to how Snort and YARA have been used in the past. Project Quarry provides a comprehensive view of agent behavior, considering the entire context of interactions, rather than just individual actions. This is crucial in identifying potential threats, as a single isolated action may not raise any alarms, but a sequence of actions may indicate a malicious intent. The tool covers various aspects of AI agent behavior, including single- and multi-turn large language model conversations, agent tool use, Model Context Protocol (MCP) interactions, and multimodal inputs. An open source version of Project Quarry is available, complete with installation instructions, supported Python versions, plugins for MCP-compatible agents, configuration examples, and rule-writing guidance.",
