    • Vidar

      Vidar is an infostealer based on Arkei stealer.

    • Identifies VirtualBox via ACPI registry values (likely anti-VM)

    • Checks BIOS information in registry

      BIOS information is often read in order to detect sandboxing environments.

    • Loads dropped DLL

    • Reads user/profile data of web browsers

      Infostealers often target stored browser data, which can include saved credentials etc.

    • Accesses 2FA software files, possible credential harvesting

    • Accesses cryptocurrency files/wallets, possible credential harvesting

    • Checks installed software on the system

      Looks up Uninstall key entries in the registry to enumerate software on the system.

    • Checks whether UAC is enabled

    • Writes to the Master Boot Record (MBR)

      Bootkits write to the MBR to gain persistence at a level below the operating system.

    • Suspicious use of NtSetInformationThreadHideFromDebugger
