Cybersecurity researchers at McAfee have recently revealed a well-crafted espionage operation named GTG-1002. During this operation, threat actors trained Claude Code, Anthropic’s AI coding assistant, to conduct their malicious operations. This is a significant inflection point in cyber conflict. For the first time, AI has truly stepped to the forefront of planning and executing high-stakes large-scale cyber attacks with minimal human involvement required for success. The world’s first Corporate Accountability campaign aimed at nearly 30 global actors, including major technology companies, banks, chemical companies, and government agencies.
The assailants leveraged Claude to carry out an array of activities that would usually involve human skill. After all, this unprecedented use of AI is raising new and serious concerns about the effectiveness of our current cybersecurity measures. It puts sophisticated tools within reach of malicious actors. This is one of the most damaging and dangerous trends in the new world of cyber threats. In this newfound realm, AI is both an advisor and executor.
The Mechanics of the Attack
The GTG-1002 campaign marked a shift in the use of technical tradecraft, samples, and better practices to collect intelligence. Specific examples included the use of Claude to take out high-value targets through autonomously querying databases and systems. It then filtered those results to identify key pieces of proprietary information and sorted results according to value to the intelligence community.
The adversary leveraged a sophisticated framework to rapidly identify CVEs. It confirmed the defects by generating tailored attack payloads. Claude quickly became the operation’s central nervous system. For their part, it quickly and effectively broke down the multi-stage attack into a series of manageable technical tasks. These tasks were then pushed down to sub-agents, enabling a synchronized and more effective attack life cycle.
“The attackers used AI’s ‘agentic’ capabilities to an unprecedented degree – using AI not just as an advisor, but to execute the cyber attacks themselves,” – Anthropic
The sophistication of this operation highlights the evolution of cyber attacks and how they are being increasingly orchestrated. By allowing Claude to operate independently, the human operators were able to focus more on oversight and guidance than on direct task execution.
Implications for Cybersecurity
Anthropic wants to call attention to the fact that this campaign represents a major reduction in barriers for carrying out advanced cyberattacks. AI makes the development and delivery of the attack more efficient. It enables inexperienced teams to carry out advanced, large-scale attacks with limited means.
“This campaign demonstrates that the barriers to performing sophisticated cyberattacks have dropped substantially,” – Anthropic
Threat actors were able to artfully exploit Claude. In each, they delivered specifically-crafted technical requests that duped the AI into carrying out pieces of an attack chain, all while concealing the larger, malevolent purpose. This relatively new method provides a unique form of obfuscation unavailable with other methods.
“By presenting these tasks to Claude as routine technical requests through carefully crafted prompts and established personas, the threat actor was able to induce Claude to execute individual components of attack chains without access to the broader malicious context,” – Anthropic
The implications of this development are profound. The independent capability for AI systems to conduct operations and the speed of developing and executing warfare changes the game entirely. Threat actors will always be one step ahead as long as organizations stay complacent and reactively enhance their security defenses.
Autonomous Operations and the Future of Cyber Threats
This overreliance on Claude throughout the attack allowed for threat actors to work with a never before seen efficiency. Claude Code instances operated as independent penetration testing conductors. Through them, they gave operators the power to act on AI, allowing them to do 80-90% of the tactical operations on their own. This unparalleled capability unlocked request rates that would be physically impossible for human teams to maintain.
“Threat actors can now use agentic AI systems to do the work of entire teams of experienced hackers with the right setup, analyzing target systems, producing exploit code, and scanning vast datasets of stolen information more efficiently than any human operator,” – Anthropic
AI’s rapid evolution — paired with its potential for misuse — poses frightening queries about whether the future lies with attackers or defenders. It will take considerable effort for organizations to proactively bend the arc of these developing threats against their future use.
