Switzerland said on January 17 that a cyberattack claimed by a pro-Russian group temporarily disrupted access to a number of government websites after Ukrainian President Volodymyr Zelenskiy's visit to Davos. The government said that the Russian-linked hacker group NoName claimed responsibility for the attack, citing Zelenskiy's attendance at the World Economic Forum. The government's National Cybersecurity Center stressed that the cyberattack was promptly detected and specialists "took the necessary action to restore access to the websites as quickly as possible." It added that an "attack of this kind had been expected, and appropriate security measures were in place."
