Attempts to exploit the Protocol Handler Vulnerability of Electron framework CVE-2018-1000006.
Electron is a common framework used by many popular applications (e.g. Skype, Teams, Slack, VSCode) which expose protocol handlers.
Which can trigger a remote code execution vulnerability via a browser vector (e.g. Chrome, Internet Explorer, Edge).
CVE: CVE-2018-1000006.

This query was originally published in the threat analytics report, Trickbot: Pervasive & underestimated.
Trickbot is a very prevalent piece of malware with an array of malicious capabilities. Originally designed to steal banking credentials, it has since evolved into a modular trojan that can deploy other malware, disable security software, and perform command and control (C2) operations.
Trickbot operators are known to use the legitimate Windows process rundll.exe to perform malicious activities, such as reconnaissance. Once a target is infected, the operator will drop a batch file that runs several commands and connects to a C2 server for further action.
The following query detects suspicious rundll.exe activity associated with Trickbot campaigns.
See Office applications launching wscript.exe to run JScript for another query related to Trickbot activity.

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-2019-1069 (also known as BearLPE), the second vulnerability listed above.

This query was originally published in the threat analytics report, Windows 7 zero-day for CVE-2019-0808
CVE-2019-0808 is a vulnerability that allows an attacker to escape the Windows security sandbox and run arbitrary code with admin privileges. This vulnerability affects Windows 7, Windows Server 2008, and Windows Server 2008 R2.
Exploits for CVE-2019-0808 were first observed as part of highly selective attacks using the Nufsys backdoor. Although the Nufsys-associated exploit was first described as a zero-day, the issue has since been patched.
The following query detects possible CVE-2019-0808 exploitation by finding suspicious file creation events associated with Nufsys.
