Researchers have demonstrated a working proof-of-concept where open-weight language models become the infection vector and propagation engine—the virus compromises a machine, then hijacks its GPU to run inference for further attacks, creating a closed loop that requires no external command infrastructure. This collapses the traditional distinction between malware and AI capability: the attack is AI-native, not just using AI as a tool. Traditional signature-based defenses and rate-limiting fail against something that adapts its exploitation strategy in real time. The shift from theoretical risk to functional prototype forces security teams and model publishers to reckon with whether open-weight model distribution—currently treated as an alignment transparency win—has become a critical vulnerability vector.
