Claim: local LLMs and ML models are exploitable quickly on a CPU — a jailbreak or permanent backdoor in minutes. Demonstrations include a Bobby Tables-style KROP injection that produces DROP TABLE, a multipart image-to-code exploit that yields a reverse shell, repository sideloading that plants a computational graph backdoor to flip numpy.loads to allow pickle, and an automated gadget hunter called autocrop plus a universal policy puppetry prompt that overrides refusals by ablating a single vector.
