Bern, 12.06.2023 - Several Federal Administration websites are/were inaccessible on Monday 12 June 2023, due to a DDoS attack on its systems. The Federal Administration's specialists quickly noticed the attack and are taking measures to restore accessibility to the websites and applications as quickly as possible.

On Monday, 12 June 2023, various websites of the Federal Administration and enterprises affiliated with the Confederation were unavailable. The Swiss government's portal www.admin.ch remains accessible.

The NoName hacker group has claimed responsibility for the attack online. This group was also behind last week's attack on parlament.ch.
