description: This search looks for processes referencing the plist files that determine
|
|
which applications are re-opened when a user reboots their machine.
|
|
data_source:
|
|
- Sysmon Event ID 1
|
|
search:
|
|
selection1:
|
|
CommandLine: '*com.apple.loginwindow*'
|
|
condition: selection1
|
|
how_to_implement: In order to properly run this search, Splunk needs to ingest process
|
|
data from your osquery deployed agents with the [splunk.conf](https://github.com/splunk/TA-osquery/blob/master/config/splunk.conf)
|
|
pack enabled. Also the [TA-OSquery](https://github.com/splunk/TA-osquery) must be
|
|
deployed across your indexers and universal forwarders in order to have the data
|
|
populate the Endpoint data model.
|
|
known_false_positives: At this stage, there are no known false positives. During testing,
|
|
no process events refering the com.apple.loginwindow.plist files were observed during
|
|
normal operation of re-opening applications on reboot. Therefore, it can be asumed
|
|
that any occurences of this in the process events would be worth investigating.
|
|
In the event that the legitimate modification by the system of these files is in
|
|
fact logged to the process log, then the process_name of that process can be added
|
|
to an allow list.
