FBI reports a massive China-linked cyberattack that compromised 260,000 devices, highlighting severe security concerns for organizations globally.

"The government’s malware disabling commands, which interacted with the malware’s native functionality, were extensively tested prior to the operation," according to the DOJ.

Federal security officials disrupted China-sponsored hackers breaching American defenses, enabling access to people’s cameras and other internet-connected devices, FBI Director Christopher Wray said 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 Flax Typhoon campaign used malware it put on cameras, video recorders and home and office routers, to create a massive network of infected computers and commit cybercrimes, the agency says.

The hackers, known as 'Flax Typhoon,' managed to build a botnet used to target government agencies and infrastructure in the U.S. and abroad
