Days after the FBI arrested a number of alleged members of the hacking group Anonymous, the hackers struck again. They claim to have stolen a gigabyte of information from the North Atlantic Treaty Organization. The group alerted the world to its latest activities via a series of tweets, including one with a link to a PDF file as evidence it had the stolen information. It is difficult to ascertain why the group, which apparently banded with the hacker organization LulzSec to carry out this particular job, chose NATO as its target.
