|
description: This analytic is to detect a suspicious modification of the active setup
|
|
registry for persistence and privilege escalation. This technique was seen in several
|
|
malware (poisonIvy), adware and APT to gain persistence to the compromised machine
|
|
upon boot up. This TTP is a good indicator to further check the process id that
|
|
do the modification since modification of this registry is not commonly done. check
|
|
the legitimacy of the file and process involve in this rules to check if it is a
|
|
valid setup installer that creating or modifying this registry.

|
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: Active setup installer may add or modify this registry.
