Joint Statement by FBI and CISA on People's Republic of China Activity Targeting Telecommunications The U.S. government is investigating the unauthorized access to commercial telecommunications infrastructure by actors affiliated with the People’s Republic of China. After the FBI identified specific malicious activity targeting the sector, the FBI and the Cybersecurity and Infrastructure Security Agency (CISA) immediately notified affected companies, rendered technical assistance, and rapidly shared information to assist other potential victims. The investigation is ongoing, and we encourage any organization that believes it might be a victim to engage its local FBI field office or CISA. Agencies across the U.S. government are collaborating to aggressively mitigate this threat and are coordinating with our industry partners to strengthen cyber defenses across the commercial communications sector.
