description: This analytic is to look for suspicious modification or creation of registry
|
|
to have service entry. This technique is abused by adversaries or threat actor to
|
|
persist, gain privileges in the machine or even lateral movement. This technique
|
|
can be executed using reg.exe application or using windows API like for example
|
|
the CrashOveride malware. This detection is a good indicator that a process is trying
|
|
to create a service entry using registry ImagePath.

data_source:
|
|
- Sysmon Event ID 13

search:
|
|
selection1:
|
|
Registry.registry_value_name: ImagePath
|
|
TargetObject: '*\\SYSTEM\\CurrentControlSet\\Services*'
|
|
condition: selection1
|
|
how_to_implement: To successfully implement this search you need to be ingesting information
|
|
on process that include the name of the process responsible for the changes from
|
|
your endpoints into the `Endpoint` datamodel in the `Registry` node. Also make sure
|
|
that this registry was included in your config files ex. sysmon config to be monitored.
|
|
known_false_positives: Third party tools may used this technique to create services
|
|
but not so common.
