Detects network activity related to the exploitation of Dahua P2P relay services via easy4ipcloud.com. The rule monitors for unauthorized device probing, serial number enumeration, and illicit relay authentication attempts (e.g., using DHP2P protocols and X-WSSE authentication), which are indicative of attackers attempting to abuse IoT device remote access functionality (CVE-2025-31702).

Detects attempts to exploit a vulnerability in WSO2 API Manager and Traffic Manager that allows for authentication bypass by utilizing a malformed JWT with the 'alg=none' header. Attackers can leverage this to impersonate users or bypass security controls by providing a crafted Bearer token in the Authorization header.

Detects a malicious command sequence targeting Redis instances where an attacker uses 'CONFIG SET' to modify the 'dir' and 'dbfilename' configuration directives followed by a 'SLAVEOF' or 'REPLICAOF' command. This is a common exploit pattern used to achieve remote code execution by forcing the Redis instance to load a malicious database file (often containing binary webshells or cron jobs) from an attacker-controlled server.

Detects malicious activities associated with the SilkParasite campaign targeting Redis servers. The rules identify the initiation of a 'SLAVEOF' command to a rogue replication host, subsequent handshake (PSYNC/REPLCONF) with an external attacker-controlled node, and the modification of server configuration ('CONFIG SET dbfilename') to potentially facilitate unauthorized file persistence or data exfiltration through the Redis replication mechanism.

This rule detects attempts to exploit a path traversal vulnerability (CVE-2024-21762) in FortiOS SSL-VPN by monitoring for malformed GET requests targeting the /remote/fgt_lang endpoint. The rule also tracks successful exploitation by identifying HTTP 200 responses containing Linux password file patterns (root:x:0:0:), indicating potential remote file disclosure.
