Ukrainian hackers take down several NATO websites because of U.S. interference in Crimea

Hackers brought down several public NATO websites in what appears to be the latest escalation in cyberspace over growing tensions over Crimea.

The Western military alliance’s spokeswoman, Oana Lungescu, said on Twitter that the cyber attacks, which began on Saturday evening, continued on Sunday, although most services were eventually restored.

‘It doesn’t impede our ability to command and control our forces. At no time was there any risk to our classified networks,’ another NATO official said.

NATO’s main public website (, which carried a statement by Secretary-General Anders Fogh Rasmussen saying that Sunday’s referendum on Crimea’s status would violate international law and lack legitimacy, worked intermittently.
