Ukraine’s Governmental Computer Emergency Response Team (CERT-UA) announced that Russia’s state-backed threat group Sandworm launched two waves of cyberattacks against an unnamed Ukrainian energy facility. The attackers tried to decommission several infrastructural components of the facility that span both IT and operational technology, including high-voltage substations, Windows computers, servers running Linux operating systems, and network equipment.
CERT-UA said that the initial compromise took place no later than February 2022, although it did not specify how the compromise occurred. Disconnection of electrical substations and decommissioning of the company’s infrastructure were scheduled for Friday evening, April 8, 2022, but “the implementation of the malicious plan” was prevented.
