I mean it happens, right? I mix up my "work" and "totally not work and NSFW for that matter" thumb drives all the time.
The IRS is contacting the current and former employees involved, almost all of whom worked in Pennsylvania, Delaware and New Jersey. The information dates to 2007, before the IRS started using automatic encryption.
IRS officials were told of the breach “a few days ago,” Koskinen’s message said.
The Social Security numbers, names and addresses of employees and contract workers were potentially accessible online because the thumb drive was plugged into the employee’s “unsecure home network,” Koskinen’s message said.
It is unknown at this time whether or not the employee is still employed by the IRS but Koskinen assured employees in his message today that they are totally taking this seriously, guys, so it's cool.
