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 use SysInternal utilities such as ProcDump to dump credentials from LSASS. They often use these stolen credentials to turn off security software, run malicious commands, and spread malware throughout an organization.
The following query detects ProcDump being used to dump credentials from LSASS.
The See also section below lists links to other queries associated with DoppelPaymer.

This query was originally published in the threat analytics report, RDP ransomware persists as Wadhrama.
The ransomware known as Wadhrama has been used in human-operated attacks that follow a particular pattern. The attackers often use Remote Desktop Protocol (RDP) to gain initial access to a device or network, exfiltrate credentials, and maintain persistance.
The following query checks for possible Wadhrama-related activity, by detecting the technique these attackers have used in the past to dump credentials.
Other techniques used by the group associated with Wadhrama are listed under See also.
