Hand over the keys for Shannon’s shenanigans
Summary: Keygraph released Shannon, a fully autonomous AI penetration testing tool that hunts for attack vectors in application code and uses a built-in browser to execute real exploits such as injection attacks and auth bypass to prove a vulnerability is exploitable. Shannon requires access to the application's source code, repository layout, and AI API keys, and Cisco Talos notes Anthropic's Claude Opus 4.6 shipped the same week with a new detection layer for identifying and responding to Claude cyber misuse.
Bottom line: To run Shannon, an organization hands an autonomous agent its source code, repository layout, and AI API keys - the same credentials and internals an attacker would want, given to a tool whose job is to find and execute exploits.
