Detects an exploitation attempt against a known SQL injection vulnerability (CVE-2026-62262) in the Piwigo photo gallery application, specifically targeting the 'pwg.images.filteredSearch.create' method via the 'ratings' parameter. The detection monitors inbound HTTP traffic for common SQL injection patterns like UNION SELECT, SLEEP commands, and boolean-based injection payloads.
Detects HTTP POST requests with 'photo' in the URI and Gzip-compressed body content, which is a known C2 communication pattern used by the IcedID banking trojan.
Detects HTTP traffic patterns associated with the default staging URIs of the PowerShell Empire C2 framework. This rule identifies inbound requests to specific .php files (admin/get, news, login/process) with a 'session=' cookie, which are characteristic of Empire agent beaconing behavior.
Detects network traffic associated with the BotHelper RAT communicating with its C2 domain 'easyllms.xyz'. The rule monitors for TLS SNI connections to this domain and specific HTTP API paths (/api/v1/ping, /api/v1/connect, etc.) indicative of command-and-control heartbeats and task execution.
This rule monitors for known malicious indicators, including a specific file hash, a C2 IP address, a remote URL associated with potential malicious activity (anydesk.exe), and a domain associated with C3Pool crypto-mining activity, across device processes, network events, and file operations.

Detects network activity associated with the Psychedelic Stealer malware, including C2 check-ins, API-based tasking, and communication with known C2 infrastructure using specific URI patterns and headers like 'X-API-Key'.
Detects HTTP traffic originating from internal hosts to external destinations on port 8989, specifically targeting '/chat/completions' URI patterns. This activity is indicative of the CARBONATO/Hermes Agent leveraging LLM gateway infrastructure as a command-and-control (C2) channel.
Detects specific HTTP traffic patterns associated with the RatHat malware's FRP (Fast Reverse Proxy) reverse-tunneling deployment and C2 status reporting. The rule identifies the sequence of fetching configuration, initiating WebSocket tunnel links, and reporting deployment status to a remote command-and-control server.
Detects network activity associated with the NeedyMantis malware command and control (C2), including DNS queries for the domain corp.tripswithengine.com, TLS SNI identification, and specific HTTP beaconing patterns to /library/zip/ with a hardcoded user agent.
Detects HTTP traffic associated with the NeedyMantis malware, specifically identifying initial beacons to a known C2 domain using a specific User-Agent, followed by command-and-control response headers that suggest the exfiltration of reconnaissance data via the Set-Cookie field.
Detects network patterns associated with NeedyMantis-style command-and-control (C2) activity. This includes specific HTTP GET requests with hardcoded User-Agent strings, cookie-based binary data transfer in server responses, and WebSocket communication attempting to establish binary protocol channels.
Detects outbound network requests to known infrastructure associated with the ClickFix Traffic Direction System (TDS), specifically targeting domains 'fsputnik.com' and 'uasputnik.com'. The rules monitor for requests to specific lure pages, tracker files, and established IP connections used by this malicious campaign to deliver fraudulent prompts or lures to victims.
Detects anomalous outbound HTTP/TLS requests to rutracker.org that contain a GUID-like identifier in the URI or deviate from normal user traffic patterns, which is characteristic of the 'VPN-for-X' browser extension acting as a command-and-control beacon.
Detects attempts to bypass Vite development server file access restrictions by appending query parameters such as ?raw, ?import&raw, or ?import&url&inline to request paths for sensitive files like .env, cloud credentials, and terraform state files.
This rule detects outgoing HTTP POST requests to the '/api/credentials' endpoint, which is characteristic of the AMOS (Atomic macOS Stealer) malware family communicating with its command-and-control server to exfiltrate stolen sensitive information.
Detects HTTP beaconing patterns and TLS SNI traffic associated with the Sauron Loader malware. The rules identify specific URI structures (including versioned resources and various configuration/profile endpoints), specific URL parameters used for session management, and characteristic User-Agent strings. Additionally, it monitors for connections to known command-and-control infrastructure via TLS SNI filtering.
Detects suspicious HTTP requests directed at SharePoint applications containing a malformed Register directive. The rule identifies attempts to leverage the 'publishingribbon' Tagprefix combined with unauthorized namespaces (e.g., System.Xaml, System.Windows.Data) to bypass the EditingPageParser.InitializeRegisterTable safelist check, a common technique for SharePoint remote code execution.
Detects two distinct suspicious patterns: first, the deletion of executable files residing in common user-writable temporary directories (e.g., Temp, Downloads, AppData) using command-line tools like 'del' or 'erase', which is often indicative of anti-forensic activity after malware execution. Second, it monitors for network traffic involving HTTP POST requests or specific SOAP headers related to 'tempuri.org', which are commonly associated with default .NET WCF service scaffolding and may be used by adversaries for C2 communication or exfiltration.

Detects network activity associated with the 'ClickFix' social engineering campaign, which commonly targets users with fake error messages to trick them into executing malicious commands. The rule identifies communication with known malicious infrastructure (domains and IP addresses) found in CommonSecurityLog events, while implementing filters to exclude common security scanners and deduplicating per-host alerts.
