There have been 27 major cyberattacks against Ukraine since 2014.

The invasion of Ukraine is not only conducted through military actions on land, sea, and air, but also through cyberattacks.

According to data from the Center for Strategic and International Studies (CSIS), from 2014 to January 2022, Ukraine experienced 27 major cyberattacks.

CSIS defines a 'major cyberattack' as an attack against the digital infrastructure or computer networks of government agencies, defense institutions, technology companies, and various other digital economic crimes with losses exceeding US$1 million.

Ukraine first experienced a major cyberattack in 2014. Attacks occurred again in 2015 and 2016, once per year, then increased to three attacks throughout 2017.

The 'weapon' used in the 2017 attacks was the NotPetya ransomware, which targeted Ukrainian infrastructure in banking, power grids, airports, and others. NotPetya also attacked the shipping company Maersk, with estimated losses of US$300 million.

Ukraine experienced the highest number of major cyberattacks in 2018, reaching nine attacks per year. Throughout 2021, there were five attacks, and in early 2022, Ukraine experienced one cyberattack in January.
