Detects the execution of PowerShell scripts that use the 'Start-NetEventSession' cmdlet to initiate network event and packet capture. This activity can be leveraged by adversaries to sniff network traffic, potentially capturing sensitive information like user credentials, especially when transmitted over unencrypted protocols. This technique is often used for information gathering during an operation.

This detection rule identifies the execution of the Purple Knight tool, a free Active Directory security assessment utility developed by Semperis. Purple Knight is designed to scan for AD vulnerabilities, misconfigurations, and common attack paths. While it is a legitimate tool used by defenders, its execution in production environments may also indicate red team activity or unauthorized reconnaissance by adversaries attempting to map domain weaknesses.

This rule detects when a Python process initiates an outbound network connection. While this activity can be legitimate for tasks like package installation or updates, it can also be indicative of malicious behavior, such as a Python-based script establishing communication with a command and control (C2) server or performing network reconnaissance. The rule includes filters to reduce false positives from common activities like Anaconda updates, Jupyter Notebook local communication, and 'pip install' commands.

Detects the execution of 'whoami.exe' when its parent process is not a common legitimate shell or application, or when the parent process information is missing. This can indicate suspicious activity, as 'whoami.exe' is often used by attackers for discovery purposes.

This detection rule identifies the execution of WinPEAS (Windows Privilege Escalation Awesome Script), a post-exploitation reconnaissance tool used to discover privilege escalation paths on Windows systems. WinPEAS performs a wide range of local enumeration checks, including service misconfigurations, permission issues, token privileges, and more. Its usage is commonly observed during red team assessments and by adversaries seeking to elevate privileges after gaining initial access. WinPEAS checks are well-documented in the HackTricks knowledge base.

This rule detects the wmRAT backdoor by identifying specific byte patterns associated with its core functionalities. These functionalities include connecting to a command and control (C2) server, finding and exfiltrating files, receiving data and writing it to files, and gathering system information. The rule looks for a combination of these distinct byte patterns to minimize false positives.
