type: Hunting
|
|
description: The following hunting analytic is meant to help organizations understand
|
|
what remote access software is being used in the environment. When reviewing this
|
|
hunt, confirm the software identified is authorized to be utilized. Based on fidelity,
|
|
create a new analytic for specific utilities banned within the organization. Adversaries
|
|
use these utilities to retain remote access capabilities to the environment. Utilities
|
|
in the lookup include AnyDesk, GoToMyPC, LogMeIn, TeamViewer and much more. Review
|
|
the lookup for the entire list and add any others.

data_source:
|
|
- Sysmon Event ID 1

|
search:
|
|
selection1:
|
|
User: unknown
|
|
Computer: unknown
|
|
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 `Processes` node. In addition,
|
|
confirm the latest CIM App 4.20 or higher is installed and the latest TA for the
|
|
endpoint product.
|
|
known_false_positives: False positives will be found. Filter as needed and create
|
|
higher fidelity analytics based off banned remote access software.
