Anonymous hackers have re-targeted US military intelligence agencies, releasing two teaser documents as a "taste of what's to come".
The Anonymous collective announced the new attack on Wednesday via Twitter. The two tweets stemmed from the AnonymousIRC Twitter account and contained links to two documents, allegedly taken from U.S. Army headquarters.
Specifically, the two documents were a January 2010 Intelligence Officer handbook and an January 2008 Intelligence Support to Urban Operations document. Released as downloadable PDFs the collective described the documents as teasers, indicating its intention to do a larger data dump.
"ok guise [sic]. well, a bunch of general US mil intel docs related to diff stuff available on the #AntiSec embassy. #Anonymous #OWS," read AnonymousIRC's tweet.
The attack follows an ongoing campaign by Anonymous against the U.S. military and its contractors. Previously the collective has mounted attacks on analysis company Stratfor, biotech firm Monsanto and military contractor Booz Allen Hamilton for their current and past ties to the U.S. Army.
The leak was later credited as a part of Anonymous's ongoing Operation Anti-Security. Started in the 1990s, Anonymous re-affirmed its commitment to the movement in August 2011, when it declared war on the world's banks and governments.
Outside of attacks on the US military, to date the operation has seen Anonymous target numerous law enforcement agencies including the Italian Police, the FBI, the U.K. Serious Organised Crime Agency and even NATO.
Anonymous gave no indication as to when the second release would occur, nor the nature of the information. U.S, officials did not respond to requests for comment.
