This setting is crucial for preventing the loading of known vulnerable drivers, and its modification may indicate an attempt to bypass security controls. It is often targeted by threat actors to facilitate the installation of malicious or vulnerable drivers, particularly in scenarios involving Endpoint Detection and Response (EDR) bypass techniques. This rule applies to systems that support the Vulnerable Driver Blocklist feature, including Windows 10 version 1903 and later, and Windows Server 2022 and later. Note that this change will require a reboot to take effect, and this rule only detects the registry modification action.

The Windows command shell ([cmd](https://attack.mitre.org/software/S0106)) is the primary command prompt on Windows systems. The Windows command prompt can be used to control almost any aspect of a system, with various permission levels required for different subsets of commands. Batch files (ex: .bat or .cmd) also provide the shell with a list of sequential commands to run, as well as normal scripting operations such as conditionals and loops. Common uses of batch files include long or repetitive tasks, or the need to run the same set of commands on multiple system ' references: - https://github.com/redcanaryco/atomic-red-team/blob/f339e7da7d05f6057fdfcdd3742bfcf365fee2a9/atomics/T1059.003/T1059.003.md#atomic-test-1---create-and-execute-batch-script author: frack113 date: 2022-01-02 tags: - attack.execution - attack.t1059.003 logsource: product: windows category: ps_script definition: 'Requirements: Script Block Logging must be enabled' detection: selection_start: ScriptBlockText|contains: Start-Process selection_batch: ScriptBlockText|contains: - .cmd - .bat condition: all of selection_* falsepositives: - Legitimate administration script level: medium
