Russian hackers have been attacking Ukrainian infrastructure since the war began. The U.S. Treasury Department has announced the number of cases identified, according to the U.S. Department for the Treasury.

During the initial stages of the conflict in Ukraine, Russians executed numerous cyberattacks on Ukrainian infrastructure, targeting financial institutions. Yet as of April 2023, the number of such incidents had significantly declined, and their level of activity had decreased.

"In the weeks following Russia’s invasion of Ukraine, Russian state-sponsored cyber actors conducted a wave of cyberattacks against Ukrainian infrastructure, including several attacks targeting financial services sector entities. By April 2023, there was a significant drop in these incidents, and a lull in state-sponsored activity has continued," the Ministry stated.

Additionally, Russia persists in carrying out cyberattacks in Ukraine to cause disruption and destabilization. It also engages in network penetration and espionage in countries that support Ukraine. Furthermore, Russia executes cyber-influence operations on individuals worldwide.

"The Computer Emergency Response Team of Ukraine (CERT-UA) recorded nearly 4,000 cyber incidents between January 2022 and September 2023. This represents a three-fold increase in cyber activity to the pre-war period," the Ministry stated.

The cyber war between Russia and Ukraine extends beyond government agency attacks. Hackers from both sides have also targeted various organizations, including financial institutions, using relatively straightforward techniques like distributed denial of service (DDoS) attacks.

"In June 2023, pro-Russia hacktivist group NoName057(16) threatened to target Ukraine’s financial sector. In the following four days, numerous Ukrainian banks were targeted with DDoS attacks. Targets included four of the nation's largest commercial banks, including First Ukrainian International Bank (PUMB), State Savings Bank of Ukraine (Oschadbank), Credit Agricole Bank, and Universal Bank," the Ministry stated.
