In yet another attack on a government contractor, Anonymous claims to have carried out an attack on Tysons Corner-based consulting firm Booz Allen Hamilton.

As my colleague Jason Ukman reported on Checkpoint Washington, Booz declined to comment on the claim, directing Ukman to a tweet saying the company generally does not “comment on specific threats or actions taken against our system.”

The hacktivist collective said that it was easy to break into the firm’s databases and retrieve “90,000 military e-mails and password hashes.”

Last week, Anonymous claimed a similar attack on IRC Federal, a West Virginia-based security firm and bragged that it had data from the Army, Navy, the Department of Justice and NASA.
