Czech National Bank hit by DDoS attack

The Czech National Bank was the target of a DDoS attack on Friday, in the latest of a spate of attacks on banking institutions and the Prague Stock Exchange. The central bank said the attack may result in a slowdown or unavailability of its online services, but assured clients that no data was leaked.

The bank said that it is in contact with the National Cyber and Information Security Bureau, which is helping it to deal with the problem.

On Wednesday, five domestic banks, Česká spořitelna, Komerční banka, ČSOB, Air Bank and Fio Banka, were similarly targeted resulting in disruptions of their websites and online banking services. It later emerged that the banks were the target of a DDoS attack carried out by the pro-Russian hacktivist group NoName057.
