The US Justice Department has charged four members of the Chinese military with a 2017 data breach of credit reporting firm Equifax. The major hacking incident compromised the personal information of nearly half of all Americans. Chinese hackers allegedly stole billions of data points on Americans that could be used to cross-reference data and obtain deep insights into individual lives. The data could be used in the recruitment of spies, and the hackers may have seeded cover identities for Chinese agents inside. Around 150 million people had information, including Social Security numbers, birth dates, and driver’s license data, compromised by the Equifax breach. Equifax Chief Executive Mark Begor said the company was grateful for the Justice Department investigation.
