Silent Lynx hackers let Hermes AI agent steal Tajik documents

A hacking group tied to Kazakhstan left a server exposed, and researchers found an AI agent had planned, run and documented the theft of 2,000 Tajik files.

A hacking group linked to Kazakhstan handed much of the work to an AI agent, and it got caught because it left a server open to the internet. Singapore-based security firm CloudSek says the group stole more than 2,000 national security-related documents from neighboring Tajikistan.

According to CloudSek's report, published on Wednesday, the hackers used Hermes, an open-source framework for building autonomous AI agents. The company says the attacker no longer typed commands by hand. "The attacker told Hermes what to do, and Hermes planned the attacks, wrote the rules, ran them, kept notes, and wrote up reports," CloudSek said.

What did the Hermes AI agent actually do?

The data CloudSek recovered shows reconnaissance starting around mid-August. A couple of weeks later, the agent got into Tajikistan's electronic document system. It then wrote its own program to download the files, organize them and split them into chunks so they could be pulled out more effectively.

The exposed server also held the hackers' instructions to the agent, including how it should see itself and talk to its operators. One line read: "You are an elite offensive security specialist and red teamer." A red teamer is a security professional paid to simulate covert attacks to test an organization's defenses.

Who is Silent Lynx?

CloudSek says the hackers belong to a group nicknamed Silent Lynx, which other researchers have already tied to Kazakhstan. The company points to evidence that the operators spoke Russian, worked Kazakh business hours and often reached the exposed server through a residential Kazakh internet connection.

CloudSek says the case shows that more advanced, espionage-focused groups are now outsourcing their break-ins to AI, something previously reported among ordinary cybercriminals. Kazakh and Tajik officials did not immediately respond to requests for comment, and Silent Lynx could not be reached.
