This query looks for events that are near in time to a detected event.
It shows how you could avoid typing exact timestamps, and replace it with a simple query to get the timestamp of your pivot event (e.g. a detected event).
This is useful when you have queries that you run often - e.g. as part of your regular investigation of an alert.
Original query: filter for network logon events right before some timestamp.

Intent:
- Use MTP capability to look for insider threat potential risk indicators
- Indicators would then serve as the building block for insider threat risk modeling in subsequent tools
Definition of Insider Threat:
"The potential for an individual who has or had authorized access to an organization's assets to use their access, either maliciously or unintentionally, to act in a way that could negatively affect the organization."
This collection of queries describes the different indicators that could be used to model and look for patterns suggesting an increased risk of an individual becoming a potential insider threat.
Note: no single indicator should be used as a lone determinant of insider threat activity, but should be part of an overall program to understand the increased risk to your organization's critical assets. This in turn is used to feed an investigation by a formal insider threat program to look at the context associated with the whole person to understand the implication of a set of indicators.

This query was originally published in the threat analytics report, Doppelpaymer: More human-operated ransomware. There is also a related blog.
DoppelPaymer is ransomware that is spread manually by human operators. These operators have exhibited extensive knowledge of system administration and common network security misconfigurations. For example, they may use net.exe to run reconnaissance and find service accounts to target. They often use stolen credentials from over-privileged service accounts to turn off security software, run malicious commands, and spread malware throughout an organization.
The following query detects the net.exe reconnaissance method described above.
The See also section below lists links to other queries associated with DoppelPaymer.
