UAC-0088 is a destructive intrusion cluster tracked by CERT-UA and associated with the DoubleZero wiper malware. The activity emerged during the 2022 Russia-Ukraine conflict and was directed at disrupting the operations of Ukrainian organizations, including critical information infrastructure. DoubleZero is a .NET-based wiper that damages Windows boot-related components and other system data by overwriting targeted content with null bytes, rendering affected systems unable to boot after restart. Observed behavior indicates the malware enumerates logical drives, user data locations, registry hives, and boot configuration data, and attempts to wipe critical boot files and related system artifacts. Reporting indicates the malware likely required administrative privileges for full impact and may in some cases have been manually executed after attackers obtained or escalated privileged access. UAC-0088 has been reported in the broader context of hostile cyber activity linked to organizations affiliated with the government or security services of the Russian Federation and Belarus, but a definitive standalone attribution for UAC-0088 beyond that context is not established here. The cluster is also referred to in connection with DoubleZero.
