Ukraine’s domestic intelligence agency revealed earlier this week that it successfully blocked more than 4,500 cyberattacks in 2022.

The Security Service of Ukraine, which protects Ukraine’s information and digital security in wartime conditions, says the number of cyberattacks has tripled since last year and increased fivefold since 2020, when only 800 cyberattacks were documented.

The chief of the SSU Cyber Security Department, Illia Vitiuk, attributed the success of his department to what it learned from the BlackEnergy cyberattack that caused power outages for about 1.4 million Ukrainians in the peak of 2015 winter.
