CERT-UA reported three cyberattacks targeting Ukraine’s state agencies and critical infrastructure to steal sensitive data.
The Computer Emergency Response Team of Ukraine (CERT-UA) reported three cyberattacks in March 2025 targeting Ukrainian agencies and infrastructure to steal sensitive data. This activity is tracked under the identifier UAC-0219.
“The Ukrainian government’s computer emergency response team, CERT-UA, is taking systematic measures to accumulate and analyze data on cyber incidents in order to provide up-to-date information on cyber threats.” reads the report published by CERT-UA. “Thus, during March 2025, at least three cyberattacks were recorded against government agencies and critical infrastructure facilities of Ukraine, aimed at collecting and stealing information from computers using appropriate software tools.”
Since fall 2024, threat actor used compromised accounts to send emails with links (e.g., DropMeFiles, Google Drive) leading to VBScript loaders that download PowerShell scripts. These scripts search for sensitive files and take screenshots for exfiltration via cURL. Attackers used NSIS installers with decoy files and IrfanView. Notably, from 2025 onwards, the screenshot functionality shifted to being powered by PowerShell. Targets included file types like .doc, .pdf, .xls, .png, and more.
The primary tool used for stealing files, tracked as WRECKSTEEL, has versions in VBScript and PowerShell. Since the stealers are not persistent, any signs of cyberattacks should be reported to CERT-UA immediately for prompt cyber protection measures.
The report includes indicators of compromise (IoCs).
