When you use a .CSV file, each thumbprint must be separated by a comma. For example: b4e72779a8a362c860c36a6461f31e3aa7e58c14,1b1d49f06d2a697a544a1059bd59a7b058cda924

    All entries that are listed in the profile are active. You do not need to select a checkbox for a thumbprint entry to make it active. Instead, use the checkboxes to help you manage the entries that have been added to the profile. For example, you can select the checkbox of one or more certificate thumbprint entries and then Delete those entries from the profile with a single action.

Attack surface reduction rules profile

Attack Surface Reduction Rules

  • Block persistence through WMI event subscription

    This attack surface reduction (ASR) rule is controlled via the following GUID: 9e6c4e1f-7d60-472f-ba1a-a39ef669e4b2

    This rule prevents malware from abusing WMI to attain persistence on a device. Fileless threats employ various tactics to stay hidden, to avoid being seen in the file system, and to gain periodic execution control. Some threats can abuse the WMI repository and event model to stay hidden.

    • Not configured (default) – The setting returns to the Windows default, which is off and persistence is not blocked.
    • Block – Persistence through WMI is blocked.
    • Audit – Evaluate how this rule affects your organization if its enabled (set to Block).

Exploit protection profile

Exploit protection

  • Upload XML
    CSP: ExploitProtectionSettings

    Enables the IT admin to push out a configuration representing the desired system and application mitigation options to all the devices in the organization.

You use the Windows Security app or PowerShell to create a set of mitigations (known as a configuration). You can then export this configuration as an XML file and share it with multiple machines on your network so they all have the same set of mitigation settings. You can also convert and import an existing EMET configuration XML file into an exploit protection configuration XML.

    Choose Select XML File, specify the XML filet upload, and then click Select.
