Create a Process Query

Create a query to investigate connections between processes, child processes, and endpoints.
From the
Query Builder
you can investigate connections between processes, child processes, and endpoints.
query-search-process.png
For example, you can create a process query to search for processes executed on a specific endpoint.
To build a process query:
  1. From Cortex XDR, select
    INVESTIGATION
    Query Builder
    .
  2. Select
    PROCESS
    .
  3. Enter the search criteria for the process query.
    • Process action—Select the type of process action you want to search: On process
      Execution
      or
      Injection
      into another process.
    • Process attributes—Define any additional process attributes for which you want to search.
      Use a pipe (
      |
      ) to separate multiple values. Use an asterisk (
      *
      ) to match any string of characters.
      By default, Cortex XDR will return results that match the attribute you specify. To exclude an attribute value, toggle the operator from
      =
      to
      !=
      . Attributes are:
      • NAME
        —Name of the process. For example,
        notepad.exe
        .
      • PATH
        —Path to the process. For example,
        C:\windows\system32\notepad.exe
        .
      • CMD
        —Command-line used to initiate the process including any arguments, up to 128 characters.
      • MD5
        —MD5 hash value of the process.
      • SHA256
        —SHA256 hash value of the process.
      • USER NAME
        —User who executed the process.
      • SIGNATURE
        —Signing status of the process: Signature Unavailable, Signed, Invalid Signature, Unsigned, Revoked, Signature Fail.
      • SIGNER
        —Signer of the process.
      • PID
        —Process ID.
      • DEVICE TYPE
        —Type of device used to run the process: Unknown, Fixed, Removable Media, CD-ROM.
      • DEVICE SERIAL NUMBER
        —Serial number of the device type used to run the process.
      To specify an additional exception (match this value except), click the
      +
      to the right of the value and specify the exception value.
  4. (
    Optional
    ) Limit the scope to a specific acting process:
    Select query-acting-process-scope.png and specify one or more of the following attributes for the acting (parent) process.
    Use a pipe (
    |
    ) to separate multiple values. Use an asterisk (
    *
    ) to match any string of characters.
    • NAME
      —Name of the parent process.
    • PATH
      —Path to the parent process.
    • CMD
      —Command-line used to initiate the parent process including any arguments, up to 128 characters.
    • MD5
      —MD5 hash value of the parent process.
    • SHA256
      —SHA256 hash value of the process.
    • USER NAME
      —User who executed the process.
    • SIGNATURE
      —Signing status of the parent process: Signed, Unsigned, N/A, Invalid Signature, Weak Hash
    • SIGNER
      —Entity that signed the certificate of the parent process.
    • PID
      —Process ID of the parent process.
    • Run search on process, Causality and OS actors
      —The causality actor—also referred to as the causality group owner (CGO)—is the parent process in the execution chain that the Cortex XDR agent identified as being responsible for initiating the process tree. The OS actor is the parent process that creates an OS process on behalf of a different initiator. By default, this option is enabled to apply the same search criteria to initiating processes. To configure different attributes for the parent or initiating process, clear this option.
  5. (
    Optional
    ) Limit the scope to an endpoint or endpoint attributes:
    Select query-host-scope.png and specify one or more of the following attributes:
    • HOST
      HOST NAME
      ,
      HOST IP
      address,
      HOST OS
      , or
      HOST MAC ADDRESS
      .
    • PROCESS
      NAME
      ,
      PATH
      ,
      CMD
      ,
      MD5
      ,
      SHA256
      ,
      USER NAME
      ,
      SIGNATURE
      , or
      PID
    Use a pipe (
    |
    ) to separate multiple values. Use an asterisk (
    *
    ) to match any string of characters.
  6. Specify the time period for which you want to search for events.
    Options are:
    Last 24H
    (hours),
    Last 7D
    (days),
    Last 1M
    (month), or select a
    Custom
    time period.
  7. Choose when to run the query.
    query-save-options.png
    Select the calendar icon to schedule a query to run on or before a specific date,
    Run in background
    to run the query as resources are available, or
    Run
    to run the query immediately and view the results in the
    Query Center
    .
  8. When you are ready, View the Results of a Query.
