The digital perimeter of the state is being aggressively privatised. Anthropic has formally restricted public access to its Mythos autonomous hacking model, deploying it exclusively through Project Glasswing to a consortium of vetted corporate monopolies and federal security agencies. The model possesses an unprecedented capacity to autonomously identify and exploit zero-day vulnerabilities across major operating systems. By hoarding this vulnerability discovery engine, Anthropic operates as a sovereign security vendor, pricing the digital commons out of the next generation of cyber defence. This restriction signals the end of the open-source artificial intelligence era. The architecture of national security now relies entirely on the intellectual property of a few hyperscale technology firms. Traditional patch cycles are collapsing under the sheer volume of algorithmic exploitation, forcing institutions to rely on the very entities that created the threat. Federal infrastructure agencies are coordinating closely with Anthropic, effectively outsourcing the defence of government networks to a private actor. The model establishes an absolute cognitive enclosure where only those with elite clearance can access the tools necessary for digital survival. Bad actors excluded from this walled garden will inevitably turn to synthetic identity fraud, which has already witnessed an eight-fold global increase over the past year. The state does not regulate this technological monopoly. It merely partners with it to ensure its own survival.
