Anonymous claims NATO hack, withholds pilfered information

Hackers with the group Anonymous claimed Thursday that they had hacked into the servers of the North Atlantic Treaty Organization (NATO). However, it wouldn't release much of the gigabyte of information it stole because doing so would be "irresponsible," seemingly indicating some of the data may be sensitive to security interests.

"Yes, #NATO was breached. And we have lots of restricted material," the group tweeted over its @AnonymousIRC account. "In the next days, wait for interesting data :)"

Anonymous claimed that the hack was done by a SQL injection, which seems to be the common method of attack used by most of these hacktivist groups. Several documents have already been disclosed via Twitter, and NATO is reportedly looking into what the group may have been able to pilfer from its servers.

"We strongly condemn any leak of classified documents, which can potentially endanger the security of NATO Allies, armed forces and citizens," a spokesperson told the Guardian.

So far the first document leaked is from 2007 and describes the communications system used by NATO forces in Afghanistan. The second, from 2008, talks about proposals to outsource communication systems for NATO forces in Kosovo. Both are marked "NATO Restricted."

Anonymous has already responded to NATO's statement, apparently attempting to look like the responsible party -- despite the fact it all but committed a crime in the first place by breaking into the group's servers. "RLY. Guess what we did NOT leak?" it responded.
