description: This analytic detects a suspicious registry modification to disable Windows
|
|
hotkey (shortcut keys) for native Windows applications. This technique is commonly
|
|
used to disable certain or several Windows applications like `taskmgr.exe` and `cmd.exe`.
|
|
This technique is used to impair the analyst in analyzing and removing the attacker
|
|
implant in compromised systems.

|
how_to_implement: To successfully implement this search, you must be ingesting data
|
|
that records registry activity from your hosts to populate the endpoint data model
|
|
in the registry node. This is typically populated via endpoint detection-and-response
|
|
product, such as CarbonBlack or endpoint data sources, such as Sysmon. The data
|
|
used for this search is typically generated via logs that report reads and writes
|
|
to the registry.
