Denial-of-service (DoS) attacks have been recorded on a number of Finnish websites.
The Bank of Finland reported that a DoS assault was made against its website. In a social media post, the central bank said that countermeasures have been started.
The disturbances, according to Turun Sanomat and Salon Seudun Sanomat, have stopped. A DoS assault had been directed at it, Turun Sanomat stated.
Additionally, Rantapallo, Yritystele, A-Katsastus, and Expat-Finland reported cyber-attacks. The latter three appeared to still be offline by early afternoon.
On its Telegram channel, the Russian hacker collective NoName claimed responsibility for the denial-of-service attacks on the websites of Finland. It justified its strikes by pointing to Finland's backing of Ukraine and the sanctions placed on Russia.
