Hacker uses DeepSeek AI to autonomously attack vulnerable servers
A Chinese-speaking threat actor is using the DeepSeek AI model and the open-source Hermes Agent to conduct autonomous cyberattacks on exposed servers. The activity was discovered by Palo Alto Networks' Unit 42 researchers, who found that the autonomous attacks did not successfully compromise the targeted servers. The campaign illustrates an offensive AI workflow capable of discovering, evaluating, and attacking vulnerable systems.
- ▪The threat actor used DeepSeek as the reasoning engine behind Hermes Agent, an open-source AI framework capable of interacting with operating system terminals.
- ▪The agent was configured to accept instructions from a Telegram channel, use custom offensive-security skills, and integrate with the FOFA internet asset search engine.
- ▪The autonomous attempts failed to compromise any targets, but the campaign is significant because the agent independently researched vulnerabilities and determined which targets were the best option.
- ▪The threat actor also conducted manual attacks against more than 460 systems using vulnerabilities affecting various products.
- ▪Unit 42 confirmed three successful compromises targeting the Citrix NetScaler vulnerability CVE-2026-3055.

Hacker uses DeepSeek AI to autonomously attack vulnerable servers By Lawrence Abrams July 31, 2026 01:35 PM 0 A Chinese-speaking threat actor is using the DeepSeek AI model and the open-source Hermes Agent to conduct autonomous cyberattacks on exposed servers with limited human involvement. The activity was discovered by Palo Alto Networks' Unit 42 researchers after Hermes accidentally created a web server from its home directory, exposing the attacker's environment, including API keys, exploit scripts, target lists, shell history, and AI attack logs.
