Rootkit
Adversaries may use rootkits to hide the presence of programs, files, network connections, services, drivers, and other system components. Rootkits are programs that hide the existence of malware by intercepting/hooking and modifying operating system API calls that supply system information.

Correlation
No remediation guidance specified
If the following pattern or patterns match an ingested event within the given time window in seconds, trigger an incident.
600 seconds
If the following defined pattern/s occur within a 600 second time window.
UEBA
This is the named definition of the event query, this is important if multiple subpatterns are defined to distinguish them.
This is the query logic that matches incoming events
eventType CONTAIN "FINS-Windows-file-" AND activityName IN ("file created", "file moved", "file read", "file renamed", "file written") AND procName = "rdpclip.exe" AND user NOT REGEXP ".*\$$|dwn-.*|dwm-.*|umfd-.*|.*SYSTEM.*|.*ANONYMOUS.*"
This defines how matching events are aggregated, only events with the same matching attribute values are grouped into one unique incident ID
hostName,domain,user,procName,activityName,resourceName
This is most typically a numerical constraint that defines when the rule should trigger an incident
COUNT(*) >= 1
This section defines which fields in matching raw events should be mapped to the incident attributes in the resulting incident.
The available raw event attributes to map are limited to the group by attributes and the aggregate event constraint fields for each subpattern
hostName = UEBA.hostName,
domain = UEBA.domain,
user = UEBA.user,
procName = UEBA.procName,
activityName = UEBA.activityName,
resourceName = UEBA.resourceName
