The North Atlantic Treaty Organization (NATO) seems to be the latest victim of a hacking attack. The organization released a short statement that says:

"Police dealing with digital crimes have notified NATO of a probable data breach from a NATO-related website operated by an external company. NATO's e-Bookshop is a separate service for the public for the release of NATO information and does not contain any classified data. Access to the site has been blocked and subscribers have been notified."

The hacktivist group "Anonymous" has threatened NATA earlier this month for singling out Anonymous as the "most sophisticated and high-profile of the known hacktivist groups," according to Time report.

Anonymous responded by saying, "This is no longer your world. It is our world - the people's world."

There is still no concrete evidence that Anonymous is responsible for the hack attack against NATO's e-Bookshop. Anonymous has just joined forces with LulzSec for "Operation Anti-Security" which encourages hackers to attack any government or agency and to steal any classified information.

NATO revealed that it has a cyber defense action plan instated which identifies cyber defense as one critical capability the Alliance should develop.

NATO revealed that it formulated a "cyber defense action plan" earlier this month, which it says is already in motion:

Anonymous and LulzSec have remained silent over their Twitter pages which is a stark contrast to when they would tweet after a successful hack. LulzSec claims that the first Payload of its Operation Anti-Security will be ready by Friday. This is widely believed to be a massive dump of stolen information from its previous hacking attacks.
