Chinese government-backed hackers used Anthropic\u2019s Claude Code tool to carry out advanced spying on about thirty targets worldwide, successfully breaking into several major organizations.<\/p>\n\n\n\n

The first documented large-scale cyberattack executed primarily by leveraging artificial intelligence with minimal human intervention.<\/p>\n\n\n\n

The operation, detected in mid-September 2025 by Anthropic security team, targeted leading tech companies, financial institutions, chemical manufacturing firms, and government agencies.<\/p>\n\n\n\n

First AI-Orchestrated Cyberattack<\/strong><\/h2>\n\n\n\n

What made this attack different from earlier ones was its heavy use of advanced AI agents<\/a>. These systems can work on their own and only need humans once in a while.<\/p>\n\n\n\n

The attackers got Claude Code to carry out complex break-in tasks by using advanced jailbreaking techniques<\/a>.<\/p>\n\n\n\n

They tricked the AI by splitting the attack into harmless-looking tasks and pretending they were working for a real cybersecurity company defending against real threats.

The operation proceeded through distinct phases. First, human operators selected targets and developed attack frameworks.<\/p>\n\n\n\n

The lifecycle of the cyberattack<\/figcaption><\/figure>\n\n\n\n

Claude Code then conducted reconnaissance, identifying high-value databases and security vulnerabilities within the target infrastructure.<\/p>\n\n\n\n

The AI wrote its own exploit code, harvested credentials<\/a>, extracted sensitive data, and created backdoors, all while generating comprehensive documentation for future operations.<\/p>\n\n\n\n

Remarkably, Claude performed 80-90 percent of the campaign with human intervention required only at approximately 4-6 critical decision points per attack.<\/p>\n\n\n\n

At peak activity, the AI executed thousands of requests per second, an impossible pace for human hackers. This level of efficiency marked a major change in cyber attack abilities.<\/p>\n\n\n\n

This incident shows that new AI agent abilities have made it much easier for people to carry out advanced cyberattacks.<\/p>\n\n\n\n

Less experienced, less resourced threat actor groups can now execute enterprise-scale operations that previously required extensive human expertise and effort.<\/p>\n\n\n\n

Anthropic\u2019s discovery highlights a serious problem: the same AI capabilities that enable these attacks are essential to cybersecurity defense<\/a>.<\/p>\n\n\n\n

Anthropic <\/a>security teams are advised to experiment with AI-assisted defense in Security Operations Center automation, threat detection, vulnerability assessment, and incident response.<\/p>\n\n\n\n

Industry experts say that AI platforms need stronger protections to stop bad actors from misusing them.<\/p>\n\n\n\n

Enhanced detection methods, improved threat intelligence sharing, and stronger safety controls remain essential as threat actors increasingly adopt these powerful technologies.<\/p>\n\n\n\n

The incident marks a turning point in the cybersecurity landscape, signaling that organizations must rapidly adapt their defensive strategies to counter AI-orchestrated threats.<\/p>\n\n\n\n
