US officials say they are seizing seven internet domains in a new effort to disrupt hackers working with Chinese IT firm Integrity Technology Group.

In a statement issued on Thursday, the Justice Department said the domains were being used to help Chinese hackers scan and hack US and foreign critical infrastructure systems.

The department said the move was the second public effort to disrupt Integrity Tech's hacking infrastructure. In September 2024, the department announced the court-authorized disruption of an Integrity Tech botnet consisting of more than 250,000 compromised consumer devices in the United States and across the world.

At the time, then-FBI Director Christopher Wray said that Integrity Tech was behind a major Chinese hacking group nicknamed "Flax Typhoon" and was carrying out intelligence collection and reconnaissance functions for Beijing's security agencies.

The Chinese Embassy in Washington did not immediately return a message seeking comment after business hours on Thursday. Beijing routinely denies carrying out hacking operations.
