U.S. law enforcement has disrupted a second major Chinese hacking group nicknamed "Flax Typhoon" and wrested thousands of compromised devices from its grasp, FBI Director Christopher Wray said on Wednesday.

The FBI, NSA and other U.S. government agencies detailed a Chinese-government operation that used 260,000 of internet-connected devices to launch cyberattacks.

The U.S. Federal Bureau of Investigation, in collaboration with other agencies, has disrupted a botnet that consisted of more than 200,000 consumer devices worldwide.
