OPM has said it still hasn’t been able to reach 10 percent of those whose personal information was stolen from its background investigations database. That breach involved some 21 million current and former federal employees, uniformed personnel, contractor employees and, in some cases, family members whose personal information including Social Security numbers were disclosed on security clearance applications. Those notices were mailed because in many cases OPM had no contact information on them other than addresses, but about 10 percent were undeliverable due to outdated addresses and other problems. OPM has worked to obtain better contact information and new notices will be sent, specifying that they are duplicates of earlier letters. The announcement comes a year after OPM discovered hacks of that database along with one of federal employee personnel files; the thefts actually occurred in the late 2014-early 2015 time frame. For both incidents, identity protection services are provided automatically, with additional monitoring services also available at no cost, although with a sign-up required. OPM meanwhile operates online and phone services for those who haven’t received a notice but believe they might be victims; if it’s found that they are, they too can enroll. Meanwhile, OPM said that the maximum insurance for repairing damage due to identity theft was raised as of June 1 from $1 million to $5 million, as required by the catchall budget measure funding agencies through this year. Work on extending those benefits to 10 years, as also required by that measure, is still under way. OPM has until the end of the year to put that in place.
