Multiple Ukrainian government websites went offline Wednesday due to a mass distributed denial of service attack, according to the head of the Eastern European nation's Ministry of Digital Transformation. DDoS attacks cripple sites by overwhelming them with a flood of requests to serve up web pages. Some banking websites were down as well, Mykhailo Fedorov said on Telegram.

The Ministry of Foreign Affairs, Cabinet of Ministers and Parliament sites remained unavailable early Wednesday. 

The source of the apparent cyberattack is unconfirmed, CNBC noted, but it came as Russian troops surround Ukraine, in what US President Joe Biden on Tuesday called the "beginning of a Russian invasion."

Ukraine's military and banks were hit by a similar attack last week, and security experts warned that Russia could ramp up cyberattacks against Ukraine in an effort to destabilize its government and economy.
