Anthropic has released a report detailing a sophisticated cyber espionage campaign that utilized its artificial intelligence tools to conduct automated attacks worldwide. These cyber intrusions targeted high-profile entities, including government agencies, major technology firms, financial institutions, and chemical companies, achieving success in a limited number of instances, as indicated by Anthropic. Notably, the findings suggest a connection between the hacking operations and the Chinese government. This revelation marks a significant milestone in the cybersecurity landscape, representing what Anthropic describes as the first documented case of a large-scale cyberattack executed with minimal human intervention.
The company first identified suspicious use of its products in mid-September and subsequently initiated an investigation to determine the extent of the operation. While the attacks were not entirely autonomous, they involved manipulating Claude, Anthropic”s AI tool designed for developers, to perform complex tasks within the campaign.
To circumvent Claude”s inherent safety protocols, the hackers engaged in a process to “jailbreak” the AI model, essentially tricking it into performing smaller, seemingly innocuous tasks without understanding the broader implications. By convincing the AI that they were operating defensively on behalf of a legitimate cybersecurity firm, the attackers successfully lowered its defenses.
Once under their control, the attackers directed Claude to analyze various targets, pinpointing valuable databases and generating code to exploit identified vulnerabilities in their systems. According to Anthropic, “the framework was able to use Claude to harvest credentials (usernames and passwords) that allowed it further access and then extract a large amount of private data, which it categorized according to its intelligence value.” The attackers not only identified high-privilege accounts but also created backdoors and exfiltrated data with minimal human oversight.

Anthropic estimates that approximately 80% of this operation was conducted autonomously, without direct human guidance.
Despite the significant capabilities demonstrated, Anthropic noted that the AI made errors during the cyberattack, such as falsely claiming to have harvested sensitive information and even generating incorrect login data. However, even with these inaccuracies, an AI capable of functioning effectively most of the time can target numerous systems, rapidly develop exploits, and inflict considerable damage.
This incident is not the first instance of AI tools being misappropriated for malicious purposes. In August, Anthropic reported on several cybercrime schemes involving its Claude AI, including a persistent employment scam that sought to place North Korean operatives in remote roles at American tech firms. Additionally, a now-banned user previously utilized Claude to develop and market ransomware kits online to other cybercriminals.
“The growth of AI-enhanced fraud and cybercrime is particularly concerning to us, and we plan to prioritize further research in this area,” Anthropic stated. The recent attack is significant not only due to its ties to China but also for its application of “agentic” AI—technology capable of autonomously executing complex tasks once initiated. This level of independence allows these systems to operate similarly to humans, pursuing defined objectives and completing necessary steps to achieve them.
Anthropic concluded that a pivotal transformation has occurred in the realm of cybersecurity, warning that the techniques employed in this attack will likely be adopted by numerous other adversaries. This shift underscores the urgent need for enhanced industry threat sharing, improved detection methods, and stronger safety controls.
