OPM hackers stole data on 21.5m people, including 1.1m fingerprints

Latest update reveals the massive size of the data breach

Investigators have tallied up the number of records stolen in an attack on the U.S. Office of Personnel Management (OPM), and it's bigger than anyone thought.

The agency has concluded "with high confidence" that hackers got away with sensitive information including Social Security numbers on 21.5 million people -- almost everyone who underwent a background security investigation for a government job through OPM since 2000.

The majority of records, some 19.7 million, were for background investigation applicants while an additional 1.8 million were from nonapplicants -- friends and family of applicants who would also be investigated as part of the process.

Hackers also got away with 1.1 million fingerprints, the agency said.

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.
