Anonymous Russia, an affiliate of the Russian hacktivist group Killnet, has claimed to have launched a distributed denial-of-service attack that took down the European Parliament's website, according to BleepingComputer. Elevated external network traffic levels related to a DDoS attack have been confirmed by the European Parliament to have caused the disruption of its website. "IT experts are pushing back against it & protecting our systems," said European Parliament President Roberta Metsola in a tweet. Such an attack followed the European Parliament's resolution moving to regard Russia as a state sponsor of terrorism, isolate the country from the United Nations Security Council and other international organizations, and curb diplomatic ties between members of the Parliament and Russia in light of the war between Russia and Ukraine. Numerous U.S. and European websites have been subjected to DDoS attacks deployed by pro-Russian hacktivists since Russia's invasion of Ukraine, with several U.S. airport websites having been impacted by Killnet DDoS attacks last month.
