Some NATO websites were attacked by CyberBerkut
On the night from Saturday to Sunday, hackers brought down some public websites of NATO, Oana Lungescu, an official representative of the alliance, said on Twitter on Sunday. It is assumed that this is due to the tension around the Crimea. The cyberattacks, which began on Saturday evening, continued into Sunday, although most of the services offered by public sites were operational as of Sunday afternoon, the official said.
