"If you underwent a background investigation through OPM from 2000 or thereafter (which occurs through the submission of forms SF 86, SF 85, or SF 85P for a new investigation or periodic reinvestigation), the OPM says there is a high likelihood that anyone who filled out one of those SF forms has had their information compromised."
Keith's note: All that talk from NASA about securing personal information as they complied with HSPD-12 and ... oh well. FWIW anyone who was screened for a NASA headquarters press pass a few years back (when they actually issued them) was at risk. Guess who got an OPM letter as a result of that screening. Thanks a bunch NASA.
