The U.S. government sure has been getting hacked a lot.
In July 2014, The New York Times reported that Chinese hackers broke into the servers of the Office of Personnel Management (OPM), the agency that functions as a kind of government-wide human-resources department.
More than a year later, in May 2015, the Internal Revenue Service announced that more than 100,000 taxpayer accounts at the IRS had been breached.
Both would have been bad by themselves. But since then, the number of people affected by both of those hacks have grown.
On June 5, 2015, the OPM announced it was hacked again. It said that “as many as 4 million people [had been] affected” in a different hack.
On June 22, 2015, the OPM hack grew. CNN reported that it ensnared “an estimated 18 million current, former, and prospective employees … more than four times the 4 million publicly acknowledged.”
On July 9, 2015, the OPM reported a third hack. “More than 21 million Social Security numbers” were accessed in that leak, we reported.“OPM said 1.1 million of the compromised files included fingerprints.”
On August 17, 2015, the IRS hack grew. “The total size of the breach [is estimated] at 330,000 accounts.”
On September 23, 2015, the OPM hack grew again. “The government now estimates that 5.6 million individuals had their fingerprints stolen,” we wrote.
On February 26, 2016, IRS hack grew again. “A total of about 724,000 individuals may have had their personal information stolen by hackers,” we reported.
