    • Deletes shadow copies

      Ransomware often targets backup files to inhibit system recovery.

    • Modifies extensions of user files

      Ransomware generally changes the extension on encrypted files.

    • Checks computer location settings

      Looks up country code configured in the registry, likely geofence.

    • Drops startup file

    • Reads user/profile data of web browsers

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

    • Creates a large amount of network flows

      This may indicate a network scan to discover remotely running services.
