Investigate a file

You can use Google Security Operations to search your data for a specific file based on its MD5, SHA-1, or SHA-256 hash value.

If additional information is available for a file hash found within a customer's Google Security Operations account, this additional information is added to the associated UDM events automatically. You can search for these UDM events manually using UDM Search or by using rules.

View a file hash

To view a file hash, you can:

  • View a file in File hash view directly

  • Navigate to File hash view from another view

View a file in File hash view directly

To open File hash view directly, enter the hash value in the Google Security Operations search field and click Search.

Google Security Operations provides additional information about the file, including the following:

  • Partner engines detecting: Other security vendors who have detected the file.

  • Properties/metadata: Known properties of the file.

  • VT submitted/ITW filenames: Known malicious in-the-wild (ITW) malware submitted to VirusTotal.

You can also navigate to File hash view while investigating an asset in an another view (for example, Asset view) by completing the following steps:

  1. Open an investigation view. For example, select an asset to view it within Asset view.

  2. In the Timeline to the left, scroll to any event tied to a process or file modification, such as Network Connection.

  3. Open the Raw Log and UDM viewer by clicking the open icon in the Timeline.

  4. You can open File hash view for the file by clicking the hash value (for example, principal.process.file.md5) within the displayed UDM event.


Hash view has the following limitations:

  • You can only filter events that are displayed in this view.
  • Only DNS, EDR, Webproxy, and Alert event types are populated in this view. The first seen and last seen information populated in this view is also limited to these event types.
  • Generic events don't appear in any of the curated views. They appear only in raw log and UDM searches.
