History

Historical Context

The 2015 Office of Personnel Management breach exposed about 22.1 million federal personnel records, a state-sponsored intrusion traced to China’s Jiangsu State Security Department. FBI Director James Comey called the trove a national-security threat, prompting stronger U.S. cyber-defense policies. In 2024 the FBI seized three QTFY domains used by a Beijing-based network that had previously targeted NASA, the Federal Reserve and the Senate.
