Detects the execution of Python interpreters with command-line arguments referencing files commonly used for proxy configurations, such as 'verify3.py', 'proxy_tester', or various '.txt' files located within a '/root/proxy/' directory. This pattern is indicative of potential proxy testing, configuration, or usage of custom proxy-based command-and-control tools.

This rule detects suspicious activity involving the creation of scheduled tasks for persistence using command-line arguments indicative of tool execution (e.g., chisel, powershell) or the direct execution of hidden PowerShell scripts intended to bypass execution policy.

This rule detects command line patterns associated with common Impacket tools (wmiexec, psexec, smbexec) executed via Windows processes (cmd.exe, powershell.exe) or via network connections to ports 445 and 135 initiated by Python processes. These tools are frequently used by adversaries for lateral movement, remote service execution, and command execution on compromised systems.

This rule detects potential web shell creation on a Microsoft Exchange server by monitoring for suspicious child processes spawned by the IIS web server process (w3wp.exe) that correlate with the creation or modification of web-accessible script files (.aspx, .ashx, .asp, .dll) within the Exchange virtual directories (ecp, owa, aspnet_client). This pattern is consistent with common post-exploitation activities used by attackers to gain persistent access via web shells.

Detects the use of netsh.exe to establish a port proxy, specifically conditioned on the execution context of the Impacket atexec tool (indicated by specific naming patterns and parent processes). This activity often follows the lateral movement or execution of a remote service by a tool like Impacket.

Detects the execution of common discovery commands like 'whoami' combined with system information gathering commands (tasklist, ver, uname) when initiated by an application named 'pc-app.exe'. This pattern is frequently observed during the reconnaissance phase of an attack.

Detects the execution of the Rubeus.exe utility with command-line arguments indicative of Kerberos-related credential harvesting and abuse, such as Kerberoasting, AS-REP Roasting, and Pass-the-Ticket attacks.

Detects the execution of BloodHound/SharpHound reconnaissance tools and the presence of their generated output files (ZIP or JSON format) on a host. This rule monitors both the process creation events associated with the tool's execution and file creation events indicative of data staging or collection output.

This rule detects potentially malicious behavior associated with Microsoft Office applications, such as Word, initiating suspicious WebDAV network connections, dropping executable or sensitive files, or spawning known LOLBAS processes (rundll32, explorer, regsvr32) from suspicious directories like Temp or WebDAV paths. It also includes a blocklist for known malicious file hashes associated with these patterns.

Detects anomalous child processes spawned by a Chrome renderer process. This behavior is often indicative of exploitation attempts, such as the BlueMoon exploit kit leveraging CVE-2026-85046, where a compromised renderer attempts to escape the sandbox or execute arbitrary code in the host process.
