WASHINGTON — The inspector general at the Office of Personnel Management, which keeps the records and security clearance information for millions of current and retired federal employees, issued a report in November that essentially described the agency’s computer security system as a Chinese hacker’s dream.

But by the time the report was published, Chinese hackers had already cleaned out tens of thousands of files on sensitive security clearances, and were preparing for a much broader attack that ultimately obtained detailed personal information on at least four million current and former government employees. Even today, the agency is struggling to patch numerous vulnerabilities.

A number of administration officials on Friday painted a picture of a government office struggling to catch up, with the Chinese ahead of them at every step.
