This query was originally published in the threat analytics report, May 2019 0-day disclosures.
In May and June of 2019, a security researcher with the online alias, SandboxEscaper, discovered and published several elevation-of-privilege vulnerabilities on Github. The researcher included proofs-of-concept demonstrating how to exploit these vulnerabilities.
Patches and more information about each vulnerability are available below:
1. CVE-2019-0863 | Windows Error Reporting Elevation of Privilege Vulnerability
2. CVE-2019-1069 | Task Scheduler Elevation of Privilege Vulnerability
3. CVE-2019-1053 | Windows Shell Elevation of Privilege Vulnerability
4. CVE-2019-1064 | Windows Elevation of Privilege Vulnerability
5. CVE-2019-0973 | Windows Installer Elevation of Privilege Vulnerability
6. CVE-2019-1129 | Windows Elevation of Privilege Vulnerability
This query locates possible activity that exploits CVE-2019-1053 (also known as SandboxEscape), the third vulnerability listed above.

Use this query to find email stealing activities ran by Qakbot that will use "ping.exe -t 127.0.0.1" to obfuscate subsequent actions.
Email theft that occurs might be exfiltrated to operators and indicates that the malware completed a large portion of its automated activity without interruption.

This query was originally published in the threat analytics report, Ransomware continues to hit healthcare, critical services. There is also a related blog.
Robbinhood is ransomware that has been involved in several high-profile incidents, including a 2019 attack on the city of Baltimore, Maryland. Robbinhood operators often employ a distinctive defense evasion technique, where they load a vulnerable driver on to a target and exploit it, in order to turn off security software -- essentially using the driver as malware.
The following query detects if a device contains the vulnerable drivers. These are often, but not always, implanted on the target by operators seeking to use this technique to turn off security software.
For a query that detects a later stage of this technique, see Detect security evasion related to the Robbinhood ransomware campaign.
