The director of the Office of Personnel Management has resigned after a hack that affected 25 million Americans, Julie Davis of The New York Times reports.

In a statement, OPM said hackers stole the Social Security numbers of 21.5 million people, including 19.7 million individuals who applied for a background investigation.

The figure is much higher than OPM’s original estimate of 4 million and amounts to roughly 7% of the US population.
