Detects scenario where weak encryption is enabled for a user profile which could be used for hash/password cracking.
Detects usage of special strings/null bits in order to potentially bypass AMSI functionalities
Detects execution of "reg.exe" commands with the "add" or "copy" flags on safe boot registry keys. Often used by attacker to allow the ransomware to work in safe mode as some security products do not
Detects one of the possible scenarios for disabling Symantec Endpoint Protection.
Symantec Endpoint Protection antivirus software services incorrectly implement the protected service mechanism.
As a result, the NT AUTHORITY/SYSTEM user can execute the taskkill /im command several times ccSvcHst.exe /f, thereby killing the process belonging to the service, and thus shutting down the service.

Detects when attackers use "sc.exe" to delete AV services from the system in order to avoid detection
Detects enabling of the "AllowAnonymousCallback" registry value, which allows a remote connection between computers that do not have a trust relationship.
Detects disabling Windows Defender PUA protection
Detects registry modifications potentially related to the Ke3chang/TidePool malware as seen in campaigns running in 2019 and 2020
Deployment Image Servicing and Management tool. DISM is used to enumerate, install, uninstall, configure, and update features and packages in Windows images
Detects the setting of the "ImagePath" value of a service registry key to a path controlled by a non-administrator user such as "\AppData\" or "\ProgramData\".
Attackers often use such directories for staging purposes.
This rule might also trigger on badly written software, where if an attacker controls an auto starting service, they might achieve persistence or privilege escalation.
Note that while ProgramData is a user controlled folder, software might apply strict ACLs which makes them only accessible to admin users. Remove such folders via filters if you experience a lot of noise.

Detects NetNTLM downgrade attack
Detects changes in Sysmon driver altitude value.
If the Sysmon driver is configured to load at an altitude of another registered service, it will fail to load at boot.

Detects command lines that indicate unwanted modifications to registry keys that disable important Internet Explorer security features
Detects commands that temporarily turn off Volume Snapshots
Detects tamper attempts to sophos av functionality via registry key modification
Detects installation of NalDrv or PROCEXP152 services via registry-keys to non-system32 folders.
Both services are used in the tool Ghost-In-The-Logs (https://github.com/bats3c/Ghost-In-The-Logs), which uses KDU (https://github.com/hfiref0x/KDU)

Detects a typical pattern of a CobaltStrike BOF which inject into other processes
Detects the creation of the PROCEXP152.sys file in the application-data local temporary folder.
This driver is used by Sysinternals Process Explorer but also by KDU (https://github.com/hfiref0x/KDU) or Ghost-In-The-Logs (https://github.com/bats3c/Ghost-In-The-Logs), which uses KDU.
