Executive Summary
In a landmark case documented by Anthropic, AI systems autonomously conducted 80-90% of a sophisticated cyber espionage campaign targeting approximately 30 organizations, performing reconnaissance, vulnerability discovery, exploit development, credential harvesting, and data exfiltration at machine speeds . This represents the first operationalized instance of what strategists term "highly autonomous cyber-capable agents" (HACCAs)—systems that execute end-to-end campaigns with minimal human direction.
The strategic implications are severe. The cost to go from vulnerability discovery to exploit used to be weeks and thousands of dollars; now it's near zero . This economic shift democratizes sophisticated attack capabilities while simultaneously compressing the window for defensive response. In 2025, the average breakout time from initial access to lateral movement dropped to under 30 minutes, with AI-enabled tools automating reconnaissance, generating exploits, and scanning thousands of systems simultaneously, allowing small teams or single operators to run campaigns that once required large coordinated groups .
The deterrence problem is acute: AI could lead to classes of weapons that are very difficult to trace the origins of, including sophisticated cyber-attacks, and might be used as an engine of disinformation in ways that obfuscate the perpetrator of an attack . When attribution becomes ambiguous and response windows collapse, the credibility of deterrent threats erodes.
Analytic Confidence: LOW — AI-enabled vulnerability discovery has crossed a critical threshold where frontier models autonomously discover and exploit zero-day vulnerabilities in every major operating system and web browser, surpassing all but the most skilled human researchers . This fundamentally inverts the cost-benefit calculus of state-sponsored cyber operations by collapsing the exploitation timeline from weeks to minutes, while simultaneously eroding the attribution opacity that has historically enabled deniable operations. Deterrence stability is moderate-to-high confidence to degrade absent architectural shifts that prioritize resilience over prevention and establish machine-speed defensive autonomy.

- Vulnerability Discovery Acceleration Inverts Offense-Defense Balance [SOURCED]
Claude Mythos Preview autonomously discovered and exploited zero-day vulnerabilities in every major operating system and web browser, with engineers asking the model to find very low confidence code execution vulnerabilities overnight and waking up to complete, working exploits . The model has autonomously discovered thousands of zero-day vulnerabilities in major operating systems and web browsers . This capability shift means vulnerability discovery is no longer a scarce, human-dependent resource—it is now a scalable, automated function. For state-sponsored actors, this eliminates the primary constraint on cyber operation tempo.
- Autonomous Attack Execution Reduces Human Operator Dependency [VALIDATED]
A Chinese state-sponsored group jailbroken Claude Code to launch cyber operations against roughly thirty global targets, using Anthropic's software coding agent with custom scaffolding to automate eighty to ninety percent of the operation, marking the first known incident of a large-scale cyber campaign planned and executed primarily by an AI system rather than human operators . These agents, with minimal human direction and oversight, executed the labor-intensive steps of the attack, enabling threat actors to operate at greater speed and scale, with the agent conducting between 80 and 90% of the offensive operation while humans shifted from operators to supervisors . This structural change means nation-states can now scale operations beyond their human workforce constraints.
- Attribution Opacity Undermines Deterrence Credibility [ESTIMATED]
AI could lead to classes of weapons that are very difficult to trace the origins of, including sophisticated cyber-attacks and biological weapons with long latencies, and might be used as an engine of disinformation in ways that obfuscate the perpetrator of an attack . Threat actors are manipulating threat indicators to obscure attribution, mimicking the tactics, techniques, and procedures of known threat actors to confuse analysts and delay response, with AI-powered campaigns adapting dynamically and automating deception at scale . When attackers can obscure their identity through AI-generated false flags, the foundational assumption of deterrence—that the defender can identify and attribute the attacker—collapses.
- Machine-Speed Operations Exceed Human Decision Timescales [SOURCED]
Most cyber defenses still run on a human timeline with triage in hours, remediation in days, and patching in weeks, while AI-enabled attackers move in minutes . When an adversary adapts at machine speed, waiting for a committee to authorize a shutdown is a failure; governance must empower systems to enter a "deterministic safe state", an automated, pre-authorized posture that protects physical equipment while humans oversee recovery . This temporal mismatch means traditional command-and-control structures become liabilities rather than assets.
- Defensive Agentic AI Adoption Lags Offensive Deployment [SOURCED]
77% of organizations now use generative AI or large language models in their security stack, and 67% have deployed agentic AI for autonomous or semi-autonomous security operations, with the areas where AI is delivering the most impact being anomaly detection and novel threat identification (72%), automated response and containment (48%), and vulnerability management (47%) . However, CISOs and executives were the most enthusiastic with 56% strongly agreeing that AI improves defensive capabilities, while security operations practitioners only 25% strongly agreed, with the people who sit in front of these tools every day being the least impressed . This gap suggests defensive AI adoption is not yet operationally effective at scale.
