1,208 detections

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).

This rule detects when the Node.js runtime process (node.exe) initiates the Windows command interpreter (cmd.exe) with the '/c' flag, which is commonly used to execute commands or scripts. This behavior is frequently associated with malicious Node.js activity, such as Remote Access Trojans (RATs) or web shells, which may use the shell to execute system-level operations or bypass typical application constraints.

Detects execution and network activity related to the PamStealer / Wavel malware campaign, including the JXA dropper and associated C2 infrastructure. The rule monitors for known malicious file hashes (e.g., JXA dropper, pkgunpack utility) and network connections to identified lure, distribution, and C2 domains and URLs used by the campaign.

Detects high-frequency anonymous comment submissions to 'wp-comments-post.php' from a single IP address within a 10-minute window, characterized by minimal variations in User-Agent. This behavior is indicative of an automated script attempting to bypass comment moderation settings, potentially exploiting known vulnerabilities (e.g., CVE-2026-93485) to inject content without administrative approval.

Detects the spawning of command-line interfaces such as cmd.exe, powershell.exe, or pwsh.exe as child processes of the SharePoint web application worker process (w3wp.exe). This behavior is highly irregular for a web server process and is indicative of potential exploitation, such as remote code execution (RCE) via web application vulnerabilities.

Detects an exploitation attempt against the SharePoint WebPartPagesWebService using the GetWebPartPageConnectionInfo method. The rule monitors for suspicious input patterns such as 'Register' and 'ignoreParentFrozen' within the URI query, which are indicative of a directive injection vulnerability.

Detects the presence of specific ysoserial gadget chain strings (ActivitySurrogateSelector/ActivitySurrogateDisableTypeCheck) indicative of deserialization attacks targeting Microsoft SharePoint via System.Web.UI.LosFormatter. This typically occurs in memory within w3wp.exe processes following an initial RCE exploit, such as those targeting EditingPageParser or ToolPane.

Detects web requests to 'wp-admin/theme-install.php' containing suspicious query parameters that indicate an attempt to force an unauthenticated theme installation via a Cross-Site Request Forgery (CSRF) exploit (Click2Shell). The rule identifies requests with malicious payloads in the 'theme' parameter, specifically looking for indicators that attempt to bypass CSRF protections when originating from an external site or a non-admin session context.

This rule detects instances where the Terraform CLI tool connects to suspected lookalike domains associated with supply chain compromise attempts (e.g., hashicorp-aws[.]com or hashicorp-terraform[.]io) during common initialization or application workflows. It correlates process execution with network connection logs and optionally validates the presence of a related .terraform.lock.hcl file associated with the malicious origin.

Detects incoming HTTP requests where the 'pagename' parameter contains directory traversal sequences (e.g., '../', '..%2f'). These attempts are typically indicative of automated vulnerability scanning or exploitation attempts targeting WordPress page-template resolution logic, specifically related to CVE-2026-87902.

Detects non-browser automated HTTP clients (e.g., Python, Wget, Curl, Scrapy) downloading audio/video files from corporate public-facing pages such as Investor Relations, Press Releases, and Executive profiles. This activity is indicative of malicious reconnaissance used to harvest voice or video samples for synthetic media (deepfake) creation for future social engineering or impersonation attacks.

This rule detects potential automated network scanning activity originating from hosts that have recently executed cPanel-related processes or binaries. It flags devices that exhibit a high frequency of connection attempts across a diverse range of remote ports and IP addresses within a short timeframe after cPanel interaction, which is characteristic of worm propagation or automated exploitation attempts targeting web server management interfaces.

Detects the IIS worker process (w3wp.exe) used by SharePoint loading a specific combination of assemblies (PresentationFramework.dll, System.Xaml.dll, and System.Data.Services.dll). This behavior is indicative of an ExpandedWrapper/XamlServices.Parse() insecure deserialization gadget chain, typically associated with the exploitation of vulnerabilities like CVE-2026-65660, which enables fileless in-memory code execution.

Detects instances where the SharePoint IIS worker process (w3wp.exe) initiates command interpreters or known living-off-the-land binaries (LOLBins). This behavior is characteristic of post-exploitation activity, such as command execution following successful exploitation of SharePoint vulnerabilities involving insecure deserialization or malicious directive injection.
