Ukraine has previously endured attacks such as the mass cyber assault on its largest mobile provider, Kyivstar, in December 2023. On the other side, Russian ministries were struck by a series of attacks in June, demonstrating the reciprocal nature of these digital hostilities.
Earlier, the Ukrainian hacktivist group Cyber Resistance claimed responsibility for breaching and leaking email communications from Russia’s Ministry of Internal Affairs and other agencies. The breach highlighted Ukraine’s capability to strike back digitally, targeting Russia’s administrative operations.
On the first anniversary of the Russia-Ukraine war, in February 203, the US CISA had advised Ukrainian organizations to set up security anticipating heightened cyberattacks by Russia-linked groups.
