At least five Russian major banks came under a continuous hacker attack, although online client services were not disrupted. The attack came from a wide-scale botnet involving at least 24,000 computers, located in 30 countries.

The attack began Tuesday afternoon, and continued for two days straight, according to a source close to Russia’s Central Bank quoted by RIA Novosti. Sberbank confirmed the DDoS attack on its online services.

“The attacks are conducted from botnets, consisting of tens of thousands computers, which are located in tens of countries,” Sberbank’s press service told RIA.

The initial attack was rather massive and its power intensified over the course of the day.
