Detects execution or file presence associated with the TraderTraitor malware, specifically targeting known malicious file paths or SHA1 hashes used by the actor to masquerade as legitimate macOS system utilities (iTunesCloud, iSync, AppleAccountd).

Detects post-exploitation shell activity spawned from the IIS worker process (w3wp.exe), narrowed to command lines carrying encoded/obfuscated PowerShell flags, remote-download cradles, or basic recon/persistence commands (whoami, certutil, bitsadmin, schtasks, reg add). This reduces noise from benign w3wp.exe-initiated automation while retaining the behavioral pattern seen in the Telerik UI for ASP.NET AJAX unauthenticated RCE chain (webshell/in-memory DLL execution dropping to a shell).
Detects execution of the tar utility by the prl_disp_service process with a command line pattern indicative of command injection via the --use-compress-program flag. This technique is often used to execute arbitrary commands by embedding them within the compression program argument.

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 in-memory modification of the ntdll.dll module to patch EtwEventWrite or EtwEventWriteFull functions, a technique used by adversaries to evade Windows event tracing and suppress telemetry. The rule specifically targets activities originating from w3wp.exe, consistent with behavior observed in IIS-hosted deployments like GhostContainer.
Detects in-memory modification of the ntdll.dll module to patch EtwEventWrite or EtwEventWriteFull functions, a technique used by adversaries to evade Windows event tracing and suppress telemetry. The rule specifically targets activities originating from w3wp.exe, consistent with behavior observed in IIS-hosted deployments like GhostContainer.

This rule detects attempts by an IIS worker process (w3wp.exe) to tamper with or disable the Antimalware Scan Interface (AMSI) by monitoring for specific non-standard provider registrations or scan buffer patching events. This activity often indicates an attacker attempting to bypass security scanning within a web-based application process.
This rule detects anomalous access patterns on a specific IIS host (agent.3bb.co.th) by comparing recent traffic against a 30-day historical baseline. It identifies requests from accounts or source IPs not seen in the baseline, activity occurring during off-hours, or traffic from external sources. The rule further filters for high-volume or high-path diversity requests, which are indicative of automated reconnaissance or potential brute-force activity against the web application.
Detects anomalous, high-volume unauthenticated POST requests to the Elementor Pro 'admin-ajax.php' endpoint with the 'elementor_pro_forms_send_form' action. This behavior is indicative of potential exploitation attempts or reconnaissance associated with the Elementor Pro file upload vulnerability (CVE-2026-32475).
Detects the execution of Ruby or Yard processes where specific command-line arguments (e.g., --load) are used to invoke potentially malicious Ruby script files like evil.rb, loader.rb, or script.rb. This pattern is indicative of an adversary leveraging existing legitimate tools to execute arbitrary script code.
Detects download or installation attempts of specific trojanized versions (2.35 and 2.36) of the Admin Menu Editor Pro plugin, which were distributed via a compromised update channel on adminmenueditor.com.
Detects unauthenticated requests to the WordPress admin-ajax.php endpoint utilizing the 'super_create_nonce' action. This action allows an unauthenticated user to generate a valid session nonce, which is a critical bypass mechanism often required for the exploitation of vulnerabilities within the Super Forms plugin, such as CVE-2026-14894.
Detects instances where base64-encoded PHP code, obfuscated behind a 'data:image/gif;base64' MIME type prefix, is written to the disk as a .php file or initiated by web server processes. This pattern is commonly used in file upload bypass attacks to execute arbitrary code.

Detects indicators of the FamousSparrow threat actor, including the creation of known malicious files (e.g., DotNetNuke.ashx, start.bat), unauthorized .ashx file writes in web application directories, and suspicious command execution chains (start.bat execution or w3wp.exe spawning command-line utilities) following the creation of .ashx files.
Detects web server processes (e.g., w3wp.exe, nginx.exe, tomcat.exe) spawning command-line interpreters or utilities that could indicate remote code execution, web shell activity, or post-exploitation discovery/download attempts.
