This query visualises total emails with Malware detections summarizing the data by ThreatNames of the malware detected.
This query helps reviewing incoming email messages where the Display Name of the sender contains own or other partner company/brand name
This query helps reviewing emails accessed by end users using cloud app events data
This query shows information about high confidence phish email that has been released from the Quarantine.
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, EvilQuest signals the rise of Mac ransomware.
As of the time of this writing (October 2020), ransomware designed to target macOS is relatively rare. EvilQuest is one of the few examples of this kind of malware on the platform.
The query below can help locate an attempt to run Python in service of malicious activity by a remote operator. The command the query searches for is associated with, but not definitely indicative of, EvilQuest infections.
Other queries related to EvilQuest ransomware can be found under the See also section below.

'Threat actors may use tools such as Curl to download additional files, communicate with C2 infrastructure, or exfiltrate data. This query looks for new files being downloaded using Curl. Curl also has legitimate uses files and hosts should be reviewed to identify potentially malicious activity.
