This rule detects unusual parent or child processes associated with 'ImagingDevices.exe' (Windows Contacts). Specifically, it looks for 'ImagingDevices.exe' being spawned by 'WmiPrvSE.exe', 'svchost.exe', or 'dllhost.exe', or for 'ImagingDevices.exe' spawning any child process. This activity has been observed in connection with Bumblebee malware operations, where adversaries might abuse legitimate processes for execution or defense evasion.
Detects when the Microsoft Management Console (MMC) spawns a Windows shell or command-line executable. This behavior can indicate an adversary abusing the MMC2.0 Application COM object for remote code execution or lateral movement. The rule specifically looks for mmc.exe as the parent process of common shell executables like cmd.exe, powershell.exe, wscript.exe, cscript.exe, reg.exe, regsvr32.exe, or other scripting/command interpreters.
Detects the execution of the Chisel tunneling tool by analyzing command-line arguments. Chisel is a fast TCP/UDP tunnel, secured by SSH, and can be used for various tunneling purposes, including creating SOCKS5 proxies or reverse tunnels. This rule specifically looks for the 'chisel.exe' image name combined with common client/server commands and tunneling parameters like '-socks5', '-reverse', or '-tls-skip-verify'.
Detects the execution of the Rclone utility, which is often used by ransomware strains like REvil, Conti, and FiveHands for data exfiltration to cloud storage services. The rule looks for specific command-line arguments and image names associated with Rclone.
Detects changes to environment variables related to ETW logging via the CommandLine. This could indicate potential adversaries stopping ETW providers recording loaded .NET assemblies.
Detects a process spawned by the terminal service server process (termsvcs), which could indicate an exploitation attempt of CVE-2019-0708, commonly known as BlueKeep. The rule specifically looks for processes where the parent command line contains both 'svchost.exe' and 'termsvcs', while filtering out legitimate processes like rdpclip.exe, csrss.exe, wininit.exe, and winlogon.exe.
This rule detects the execution of the `systeminfo.exe` command, which is used to retrieve detailed system information. Adversaries often use this command during the discovery phase to gather information about the compromised system's operating system, hardware, and installed software. This information can help them understand the environment and plan subsequent actions.
This rule detects the creation or modification of a specific registry key associated with Windows Credential Editor (WCE). WCE is a tool used to dump credentials from memory, specifically targeting the Local Security Authority Subsystem Service (LSASS). The rule looks for the string 'Services\WCESERVICE\Start' within the 'TargetObject' field of registry events, indicating the installation or activation of WCE as a service.
Detects changes to registry values related to Outlook security settings, which could indicate an attempt to modify Outlook's behavior for persistence or other malicious purposes. This rule specifically looks for modifications within the 'SOFTWARE\Microsoft\Office\<version>\Outlook\Security\' registry path.
Detects when an attacker attempts to disable User Account Control (UAC) by modifying the 'EnableLUA' registry value to 0. This action can be part of privilege escalation or defense evasion tactics to bypass UAC prompts.
