This rule detects an attempted buffer overflow vulnerability (CVE-2025-9298) in Tenda routers. Specifically, it looks for HTTP POST requests to the '/goform/QuickIndex' URI where the 'PPPOEPassword' parameter contains an excessively long string (100 or more characters) that could lead to a buffer overflow.
This rule detects an attempt to exploit a buffer overflow vulnerability (CVE-2024-8573) in TOTOLINK devices. The exploit targets the `setParentalRules` function within the `/cgi-bin/cstecgi.cgi` endpoint, specifically looking for HTTP POST requests with multiple parameters (desc, week, sTime, eTime) containing excessively long values (100 or more characters), indicative of a buffer overflow attempt.
This rule detects attempts to exploit a critical authentication bypass vulnerability (CVE-2025-54309) in CrushFTP's WebInterface. The exploit leverages an alternative channel to bypass authentication, specifically targeting the '/WebInterface/function/' URI with a 'command=login' parameter and a 'crushadmin' string in the 'as2-to' HTTP header. Successful exploitation could lead to unauthorized administrative access.

ET ATTACK_RESPONSE Braodo Loader Inbound
ET ATTACK_RESPONSE KoiStealer Payload Inbound
ET ATTACK_RESPONSE TA399 Fake 404 WebPage Inbound
This rule detects attempts to exploit the Zip Slip vulnerability within TAR archives. Specifically, it looks for the sequence `../` (dot dot slash) in file paths within a TAR archive being transferred to a client, which is indicative of an attacker trying to write files outside of the intended directory.
This rule detects attempts to exploit the Zip Slip vulnerability in inbound ZIP archives. It specifically looks for the sequence '../' within the file data of a ZIP archive, which indicates an attempt to write files outside of the intended directory during extraction.
This rule detects HTTP responses (status code 200) that contain the string 'schtasks' followed by '/run' and '/tn' (case-insensitive) in the response body. This pattern indicates the potential for a client system to receive instructions to execute a scheduled task, which could be used for persistence, lateral movement, or other malicious activities.

ET ATTACK_RESPONSE TA399 Fake 404 WebPage Inbound
Detects network connections to known Command and Control (C2) servers associated with the LANDFALL Android spyware. The spyware communicates over HTTPS, often on non-standard ports.
This rule detects attempts to exploit a command injection vulnerability (CVE-2025-57105) in D-Link devices. Specifically, it looks for HTTP GET requests to '/mng_platform.asp' where the 'addr' parameter contains characters commonly used for command injection, such as semicolons, newlines, backticks, pipes, or dollar signs, which could lead to arbitrary command execution on the device.
This rule detects an attempt to exploit a buffer overflow vulnerability (CVE-2025-9299) in Tenda routers. The exploit targets the `/goform/getMasterPassengerAnalyseData` endpoint via an HTTP POST request, specifically looking for an overly long 'time' parameter in the request body, which could lead to a buffer overflow.
Lumma Stealer Payload Inbound
Suricata
This rule detects the inbound transfer of a Lumma Stealer payload over HTTP. Specifically, it looks for a unique content string within the HTTP response body, indicating the download of a DLL file associated with Lumma Stealer. The content string 'filename="fuckingdllENCR.dll"' is a strong indicator of this specific malware.
Detects the creation of a new administrator account on a Fortinet FortiGate Firewall. This activity could indicate an attacker establishing persistence or escalating privileges within the network infrastructure.
Detects network traffic to 'cloudflariz.com', a known Command and Control (C2) domain associated with the Qilin RaaS group. An alert from this rule is a high-fidelity indicator of compromise.
