There is no way to directly block SHA-1 hash values on other Trend Micro products without using Control Manager. SHA-1 hash values can only be blocked using Control Manager’s User-Defined Suspicious Object (UDSO). Other Trend Micro products sync the UDSO and take action on a file with matching SHA-1 hash value depending on the configuration.

The following products sync SHA-1 UDSO from Control Manager:

  • Interscan Messaging Security Virtual Appliance (IMSVA)
  • Interscan Web Security Virtual Appliance (IWSVA)
  • Endpoint Application Control (EAC)
  • Deep Discovery Inspector (DDI)
  • Deep Discovery Email Inspector (DDEI)

The following products DO NOT sync SHA-1 UDSO from Control Manager:

  • OfficeScan
  • Deep Security
  • Deep Discovery Analyzer (DDAn)
  • Smart Protection Server (SPS)

To block SHA-1 hash values using Control Manager, do the following:

  1. Log on to Trend Micro Control Manager.
  2. Go to Administration > Suspicious Objects > User-Defined Suspicious Objects.
  3. Click Add.

    add

  4. For the Type, select File SHA-1.
  5. Enter the SHA-1 hash value, and configure the scan action:
    • Log
    • Block
    • Quarantine

    sha1

  6. Click Add.
