Aim Labs discovered a vulnerability in Microsoft 365 Copilot named “EchoLeak,” which enables unauthorized data extraction through zero-click AI exploitation. This attack leverages the victim’s copilot to create URLs using sensitive data as query parameters, and utilizes markdown image auto-rendering for data extraction without user involvement. A very smart and dangerous tactic.
Anthropic shared insights on how their multi-agent research system enhances AI’s capacity to undertake complex investigations through parallel processing and effective coordination. As agentic systems gain momentum in the industry, such research is invaluable for those building efficient multi-agent frameworks.
