Detects the use of a scanner by zerosum0x0 that discovers targets vulnerable to CVE-2019-0708 RDP RCE aka BlueKeep

Detects events generated by user-mode applications when they call the CveEventWrite API when a known vulnerability is trying to be exploited. MS started using this log in Jan. 2020 with CVE-2020-0601 (a Windows CryptoAPI vulnerability. Unfortunately, that is about the only instance of CVEs being written to this log.

Detect suspicious error on protocol RDP, potential CVE-2019-0708

This rule is designed to detect attempts to exploit Zerologon (CVE-2020-1472) vulnerability using mimikatz zerologon module or other exploits from machine with "kali" hostname.

Detects a process spawned by the terminal service server process (this could be an indicator for an exploitation of CVE-2019-0708)

Detects log entries that appear in exploitation attempts against MS Exchange RCE CVE-2021-42321

Detects the execution of the commonly used ZeroLogon PoC executable.

Detects the exploitation of OMIGOD (CVE-2021-38647) which allows remote execute (RCE) commands as root with just a single unauthenticated HTTP request. Verify, successful, exploitation by viewing the HTTP client (request) body to see what was passed to the server (using PCAP). Within the client body is where the code execution would occur. Additionally, check the endpoint logs to see if suspicious commands or activity occurred within the timeframe of this HTTP request.
