name: Time Provider Persistence Registry
id: 5ba382c4-2105-11ec-8d8f-acde48001122

status: production
type: TTP
description: This analytic is to detect a suspicious modification of time provider
registry for persistence and autostart. This technique can allow the attacker to
persist on the compromised host and autostart as soon as the machine boot up. This
TTP can be a good indicator of suspicious behavior since this registry is not commonly
modified by normal user or even an admin.
data_source:
- Sysmon Event ID 13
search:
selection1:
TargetObject: '*\\CurrentControlSet\\Services\\W32Time\\TimeProviders*'
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.
