description: This search looks for processes in an MacOS system that is tapping keyboard
|
|
events in MacOS, and essentially monitoring all keystrokes made by a user. This
|
|
is a common technique used by RATs to log keystrokes from a victim, although it
|
|
can also be used by legitimate processes like Siri to react on human input
|
|
how_to_implement: In order to properly run this search, Splunk needs to ingest data
|
|
from your osquery deployed agents with the [osx-attacks.conf](https://github.com/facebook/osquery/blob/experimental/packs/osx-attacks.conf#L599)
|
|
pack enabled. Also the [TA-OSquery](https://github.com/d1vious/TA-osquery) must
|
|
be deployed across your indexers and universal forwarders in order to have the osquery
|
|
data populate the Alerts data model.
