Swiss websites hit by DDoS attack ahead of Zelenskiy video address

The attack comes as the Swiss parliament prepares for a video address by Ukrainian President Volodymyr Zelenskiy scheduled for Thursday. Switzerland's National Cyber Security Centre (NCSC) said that "various websites of the Federal Administration and enterprises affiliated with the Confederation were unavailable" in the wake of the attack, claimed by the NoName hacking group.

Swiss authorities said that several government websites were targeted in a distributed denial-of-service (DDoS) attack on Monday that was claimed by pro-Russian hackers. The attack comes as the Swiss parliament prepares for a video address by Ukrainian President Volodymyr Zelenskiy scheduled for Thursday.

Switzerland's National Cyber Security Centre (NCSC) said that "various websites of the Federal Administration and enterprises affiliated with the Confederation were unavailable" in the wake of the attack, claimed by the NoName hacking group. "The NCSC is analysing the attack together with the administrative units concerned and defining appropriate measures," it said in a statement.

The NCSC, which did not link Zelenskiy's upcoming address to the attack, said the NoName group had also been behind a separate attack against the Swiss parliament's website last week.
