The European Parliament website on Wednesday faced a "sophisticated" cyberattack disrupting its services moments after members voted to declare Russia a state sponsor of terrorism."I confirm that the Parliament has been subject to an external cyber attack, but the Parliamentary services are doing well to defend the Parliament," Dita Charanzová, Czech MEP and Parliament vice president responsible for cybersecurity, said in a statement.Another senior Parliament official, requesting not to be named, said “it might be the most sophisticated attack that the Parliament has known so far.”The attack is what's known as a distributed denial-of-service (DDoS) attack, in which massive amounts of traffic are sent to servers in an attempt to block internet users from accessing websites, Marcel Kolaja, European Parliament member for the Czech Pirate party, confirmed.It emerged as a favorite instrument of Russian hacking groups like Killnet, notably as a way to protest against political decisions in European countries to support Ukraine in the war.Unless there is extra attacks we expect it to be back and accessible very soon," said Eva Kaili, Greek member and vice president of the European Parliament."
