According to sources, hackers believed to be linked to China infiltrated the FBI's computer network, where warrant information for criminal suspects and surveillance targets is stored.

This system contains call records, IP addresses, and routing information of suspects and surveillance targets. However, it is reported that actual call content was not included.

The FBI released a statement saying, "We identified suspicious activity on our computer network and addressed it, and mobilized all our technical capabilities in response."

Previously, in 2024, China also breached the internal systems of U.S. telecommunications companies such as Verizon and AT&T, as well as network operators like Lumen Technologies.

At that time, Chinese hackers were also reported to have accessed the internal systems of private telecom companies, which allow law enforcement agencies such as the FBI to conduct wiretapping when presented with a warrant.

It is also reported that they attempted to wiretap the call content of dozens of key politicians, including senior officials affiliated with President Donald Trump's campaign.

The hacker group "Volt Typhoon," believed to be linked to Chinese intelligence agencies, was identified as being behind these incidents.

However, it has not been confirmed whether this recent breach of the FBI's internal computer network is also connected to Volt Typhoon.
