description: This analytic is to detect a suspicious modification or new registry
|
|
entry regarding print processor. This registry is known to be abuse by turla or
|
|
other APT to gain persistence and privilege escalation to the compromised machine.
|
|
This is done by adding the malicious dll payload on the new created key in this
|
|
registry that will be executed as it restarted the spoolsv.exe process and services.

TargetObject: '*\\Control\\Print\\Environments\\Windows x64\\Print Processors*'

condition: selection1
|
|
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 Carbon Black 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.
|
|
known_false_positives: possible new printer installation may add driver component
|
|
on this registry.
