Russian Hackers Hide Malware in Hyper‑V Alpine Linux VMs

🛡️The Russian-linked threat group Curly COMrades abused Microsoft Hyper-V on Windows hosts to deploy a hidden, minimal Alpine Linux VM that hosted custom implants: CurlyShell (reverse shell) and CurlCat (reverse proxy). By using the Hyper-V Default Switch and naming the VM "WSL," outbound C2 traffic appeared to originate from the legitimate host IP, enabling evasion of host-based EDRs. The campaign — active since mid-2024 and observed by Bitdefender with help from the Georgian CERT — also employed PowerShell scripts for LSASS Kerberos ticket injection and Group Policy-based account creation, leaving few forensic traces. Organizations are advised to monitor unexpected Hyper-V activation, abnormal LSASS access or tampering, PowerShell GPO deployments, and to implement network-level inspection and layered defenses.
