Detects malicious exploitation attempts against the SharePoint WebPartPages.asmx SOAP endpoint. Attackers use this endpoint to bypass security patches by invoking template-parsing functions like GetWebPartPageConnectionInfo, which facilitates Register-directive injection and XamlServices deserialization chains for remote code execution.
Detects the loading of an unsigned or attacker-controlled DLL into a SYSTEM-context dllhost.exe process, consistent with the exploitation of dangling COM CrossDevice CLSIDs (e.g., forcing ICreateObject::Proc3 to LoadLibrary from a C:\ProgramData location).
This rule detects potential prompt injection attacks against internal AI-powered assistants, agents, or LLM gateways. It monitors network HTTP requests for common patterns used to override system instructions, bypass safety filters, or force the model to adopt a privileged, unauthorized persona (e.g., administrator or debug mode). These techniques are often used in social engineering to manipulate the AI's output or security posture.
Detects anomalous child process spawning from common web browsers or productivity applications (e.g., Office, Acrobat) on hosts that have recently communicated with known LLM or code-generation APIs. This behavioral correlation is intended to identify the potential execution of AI-generated exploit code.
Detects an exploitation chain originating from a Chrome browser process, characterized by the execution of an anomalous child process followed by the creation of an executable file named 'chrome_cleanup.exe' within a short time window. This sequence is indicative of multi-stage exploitation, involving remote code execution via browser vulnerability and subsequent privilege escalation.
Detects potential exploitation of CVE-2026-41940 affecting cPanel/WHM, where administrative actions occur without a preceding successful login event from the same source IP within a 30-minute window. This indicates an authentication bypass attempt.
This rule detects attempts to exploit CVE-2021-33044 in Dahua devices, specifically targeting the NetKeyboard clientType during the global.login RPC request. This vulnerability allows an unauthenticated remote attacker to bypass authentication mechanisms.
This rule detects attempts to exploit the authentication bypass vulnerability in Dahua firmware (CVE-2021-33045) via the JSON-RPC interface. The attacker attempts to manipulate the 'loginType' and 'ipAddr' fields, specifically using 'Loopback' as the login type and '127.0.0.1' as the IP address to bypass security controls.
Detects unauthenticated or unauthorized access attempts to critical Oracle PeopleSoft PeopleTools endpoints (such as PSIGW, PSC, or PORTAL). These detections trigger when suspicious requests are made to these sensitive paths without expected authentication headers or session tokens, potentially indicating an exploitation attempt as described in CVE-2026-35273.
Detects an unauthenticated remote code execution (RCE) attempt against Langflow via the /api/v1/validate/code endpoint. The rule monitors for POST requests containing code execution patterns such as eval, exec, os.system, or subprocess, indicating an attacker attempting to leverage the vulnerability to execute arbitrary commands.
Detects exploit attempts targeting a Python prompt-injection vulnerability (CVE-2026-26030). The rule identifies command lines attempting to traverse Python's object hierarchy (e.g., using __class__, __base__, __subclasses__) to import the os module and execute system commands. It also flags subsequent child processes (e.g., calc.exe, cmd.exe) spawned by Python interpreters or Semantic Kernel host processes.
Detects attempts to bypass input sanitization in AI agent frameworks, specifically Semantic Kernel, by using Python bracket or subscript notation to access sensitive attributes or functions (e.g., __class__, __subclasses__, __import__, eval, exec). This technique is characteristic of filter injection attacks aiming to achieve remote code execution in AI agent environments.
This rule detects potential exploitation attempts targeting vulnerabilities within the libheif image processing library. It monitors for image processing binaries (e.g., convert, magick) executing with command-line arguments related to HEIF/HEIC files, followed by multiple application crash events (SIGSEGV, coredumps) associated with libheif on the same device within a short time window.
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.
This rule detects malicious deserialization attempts targeting Microsoft SharePoint, specifically leveraging System.Data.Services.Internal.ExpandedWrapper combined with LosFormatter and System.Xaml.XamlServices. This signature is indicative of exploitation attempts related to CVE-2026-65660, allowing an attacker to achieve remote code execution by bypassing SafeControls restrictions.
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 an attempt to exploit a quote-injection vulnerability within the SharePoint ToolPane.aspx page, specifically targeting the Register directive to bypass SafeControls restrictions. This pattern is commonly used for remote code execution or unauthorized application behavior modifications by manipulating server-side parsing.
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.
This rule detects a suspicious sequence of events indicative of a Redis Lua sandbox escape. It monitors for a network connection to Redis (port 6379) followed shortly by the redis-server process reading the system's /etc/passwd file, which is a known indicator of an attempted arbitrary file read via the EVAL command.
Detects HTTP requests targeting the /terminal/ws endpoint of a Marimo notebook application, which indicates an attempt to exploit CVE-2026-39987, a pre-authentication Remote Code Execution vulnerability involving WebSocket connections.
Detects indicators associated with the exploitation of CVE-2025-3248 in Langflow. The rule identifies anomalous web requests targeting the /api/v1/validate/code endpoint, subsequent suspicious process creation (base64 encoded payloads in Python/shell), and network communication with identified command and control (C2) or data exfiltration IP addresses. It also includes alerts for observed contact with known extortion email addresses.
