As an update to our blog post, “Data Breach Affects Millions of Current and Former Government Workers”, a union representing federal workers is now claiming that the hack may be worse than originally feared.  Yesterday, the president of the American Federation of Government Employees said his organization now believes hackers stole the personal data — including Social Security numbers — of every single federal worker.  In a letter to Katherine Archuleta, the director of the Office of Personnel Management, obtained by the Associated Press, union head David Cox wrote:

We believe that the Central Personnel Data File was the targeted database, and that the hackers are now in possession of all personnel data for every federal employee, every federal retiree, and up to 1 million federal employees.

The agency has not yet responded, and the Cox letter does not provide evidence or other information to support the claim of expanded reach.
