Joint Statement from FBI and CISA on the People's Republic of China Targeting of Commercial Telecommunications Infrastructure
The U.S. government's continued investigation into the People's Republic of China (PRC) targeting of commercial telecommunications infrastructure has revealed a broad and significant cyber espionage campaign.
Specifically, we have identified that PRC-affiliated actors have compromised networks at multiple telecommunications companies to enable the theft of customer call records data, the compromise of private communications of a limited number of individuals who are primarily involved in government or political activity, and the copying of certain information that was subject to U.S. law enforcement requests pursuant to court orders. We expect our understanding of these compromises to grow as the investigation continues.
The FBI and the Cybersecurity and Infrastructure Security Agency (CISA) continue to render technical assistance, rapidly share information to assist other potential victims, and work to strengthen cyber defenses across the commercial communications sector. We encourage any organization that believes it might be a victim to engage its local FBI field office or CISA.
