GLM-5.2, not Mythos, is the real security emergency (joshuasaxe181906.substack.com)

The recent emergence of the GLM-5.2 model marks a significant shift in the landscape of offensive cyber operations, as it liberates attackers from previously existing logging and detection hurdles associated with frontier models. Unlike its predecessors, GLM-5.2 is an open-weights model that exhibits long-horizon agency capabilities akin to those found in Opus 4.5. This development means that attackers can now easily fine-tune the model to carry out various illicit actions privately, empowering a new wave of cyber threats without the previous friction caused by detection risks. The implications for AI and machine learning are profound. With the democratization of access to near-frontier open weights, we are likely to see the emergence of a dark economy surrounding these technologies, paralleling existing markets for malware and exploits. This accessibility could enable a diverse range of attacker groups to leverage advanced AI tools for malicious intents. In contrast, defenders remain restricted from utilizing the cutting-edge capabilities of models like Anthropic’s Mythos, stunting their ability to counteract these new threats. This discrepancy could further aggravate the security landscape, leading to an escalation of cyberattacks fueled by sophisticated AI tools.
