Some of the contractors that have helped OPM with managing internal data have had security issues of their own—including potentially giving foreign governments direct access to data long before the recent reported breaches. A consultant who did some work with a company contracted by OPM to manage personnel records for a number of agencies told Ars that he found the Unix systems administrator for the project “was in Argentina and his co-worker was physically located in the [People’s Republic of China]. Both had direct access to every row of data in every database: they were root. Another team that worked with these databases had at its head two team members with PRC passports. I know that because I challenged them personally and revoked their privileges. From my perspective, OPM compromised this information more than three years ago and my take on the current breach is ‘so what’s new?'”

Given the scope and duration of the data breaches, it may be impossible for the US government to get a handle on the exact extent of the damage done just by the latest attack on OPM’s systems. If anything is clear, it is that the aging infrastructure of many civilian agencies in Washington magnify the problems the government faces in securing its networks, and OPM’s data breach may just be the biggest one that the government knows about to date.
