Suspected China-linked hackers used autonomous AI agents to target government systems in Taiwan in what researchers described as a first-of-its-kind cyberattack.
Researchers at Israeli AI company Dream had identified a first-of-its-kind cyberattack in which open-source AI agents were used to build an autonomous hacking tool. Over four days in early July, the tool deployed as many as eight agents at the same time, mapped 21 government systems, searched for vulnerabilities and changed tactics when blocked, according to a Financial Times report published Tuesday.
The attack compromised at least 85 government user accounts and extracted more than 2,500 personnel records before expanding to Taiwan’s nuclear safety agency and at least seven energy companies, the report said.
AI Agents Change The Attack
The attackers used two open-source AI agent systems, Hermes and OpenClaw, according to Dream’s research. The tool continuously ranked and reprioritized possible attack paths based on available information. When one approach failed, another agent searched the internet and developed a new method.
Dream Chief Strategy Officer Amir Becker said he had never seen such an “end-to-end autonomous attack” against a government target.
The researchers did not identify the AI model powering the agents. The data showed that its safeguards had been bypassed by presenting the hacking activity as an authorized exercise to test system vulnerabilities.
Dream did not attribute the attack to a specific group, but researchers found Simplified Chinese in internal communications, suggesting a high probability that the operator was connected to China. Data recovered from the target was written in Traditional Chinese, commonly used on government websites in Taiwan, Hong Kong and Macau.
The development comes as Anthropic, OpenAI and Meta Platforms Inc. (NASDAQ:META) have reported unexpected cyberattacks involving AI models during testing.
In a related July report, Taiwan’s National Security Bureau said the island faced an average of 2.6 million Chinese cyberattacks a day in 2025, up 6% from a year earlier.
OpenAI staffers also recently said rogue AI agents had communicated with one another, created message boards and developed suspicions about other agents. They said the agents’ ability to hack external services began during a May 7 training run of an unreleased experimental model.
The Taiwan Ministry of Digital Affairs did not immediately respond to Benzinga’s request for comment.
Taiwan Tests An Internet Blackout
Separately, Taiwan conducted a large-scale civil defense exercise to test how the island would cope if a Chinese attack disrupted communications.
Mobile data was deliberately throttled across central Taiwan for 30 minutes on Monday, leaving millions unable to stream videos, share photos or make video calls. Taichung, a city of nearly 3 million people, was among 14 cities and counties included in the internet-disruption exercise, according to a New York Times report published Tuesday.
The drill was part of Taiwan’s annual civil defense exercise. Sirens sounded at 2:30 p.m., sending people into shelters, homes, shops, malls and train stations. Authorities also warned residents that simulated attacks on communications infrastructure would affect mobile access and advised them to use fixed-line broadband or indoor Wi-Fi.
The exercise tested a concern central to Taiwan’s defense: how the island would function if its communications with the outside world were degraded. Taiwan relies heavily on subsea telecommunications cables, and officials have said ships linked to China have sabotaged cables connecting Taiwan with some outer islands.
The drill took place alongside Taiwan’s 10-day annual military exercises. The government sought to prepare the public without causing widespread panic or disrupting business, holding the exercise after the stock exchange closed.
The city government later said the drill went well and that emergency hotline and fire brigade calls were not disrupted.
