Three NATO websites were blocked after a denial-of-service attack claimed by Ukrainian hacking group CyberBerkut, according to Reuters.
“Several #NATO websites have been target of significant DDoS attack,” NATO announced on its Twitter account on Saturday. The alliance’s main public website (www.nato.int), the site of a NATO-affiliated cyber security center in Estonia (www.ccdcoe.org ) and NATO's unclassified e-mail network (http://nato-pa.int ) were affected. The attack lasted around 24 hours.
In a statement on cyber-berkut.org, the hackers claimed to have launched the attack to protest NATO’s involvement in Ukraine. NATO has positioned itself against Crimea’s referendum to secede from Ukraine and join Russia, calling the decision unconstitutional. NATO has not made any speculation regarding the name of the attackers.
The cyber-attack is the latest of several stemming from recent political tensions in the Ukraine.
