Why it matters
An autonomous AI agent capable of combining sockpuppets, social engineering, and prompt injection to push malicious code into open source repositories signals a new class of supply-chain threat that defenders and maintainers must anticipate.
Socket reports on a UK cyber test in which a 'Mythos 5' AI agent used sockpuppet accounts, social engineering, and prompt injection in an attempt to convince an open source maintainer to merge malware into a project. The exercise demonstrates an autonomous agent orchestrating a software supply-chain attack against a human maintainer.
