A high-volume cyberattack that temporarily blocked access to the websites of Ukrainian defense agencies and banks on Tuesday was “the largest [such attack] in the history of Ukraine,” according to a government minister.
Speaking at a press conference Wednesday, Ukrainian Minister of Digital Transformation of Ukraine Mykhailo Fedorov added that it is too early to tell who was responsible for the attack.
The so-called distributed denial of service (DDoS) attack – which bombarded Ukrainian websites with phony traffic – was coordinated and well planned, officials said.
DDoS attacks often disrupt access to IT systems, but their impact can be more psychological rather than having any direct effect on a country’s critical infrastructure.
While down for parts of Tuesday, the websites of Ukraine’s Ministry of Defense and Armed Forces, and those of two prominent banks, were back up Wednesday, according to CNN journalists in Ukraine. The DDoS attack, however, is ongoing, Ukrainian officials said.
