Personal information
Technical writeup
VA officials gave veteran Social Security numbers, names, and possibly other information to Ancestry.com in March of 2011 in response to a Freedom of Information Act request from the genealogy site. The records should have only contained the information of deceased veterans, but instead contained the information of over 2,200 living veterans. The information was then posted in 2011 and taken down in January of 2012.
