VOLTMARKER
VOLTMARKER is a malware payload observed by Mandiant in related activity involving the threat cluster UNC4108. The provided content states that UNC4108, a cluster with unknown motivation, used PowerShell to deploy VOLTMARKER and NetSupport RAT and also conducted reconnaissance. Mandiant further observed that access initially obtained through UNC5518’s financially motivated ClickFix campaign was leveraged by other groups, including UNC4108, which distributed VOLTMARKER in that follow-on activity. The available content does not provide additional high-confidence technical details on VOLTMARKER’s functionality, persistence, infection mechanism beyond PowerShell-based deployment, targeted industries, or specific indicators of compromise.
