Monsterv2 C2 Detection From The Clickfix Campaign
This rule identifies network activity that could be indicative of command and control (C2) communication or reconnaissance. It specifically looks for two patterns: DNS queries to 'api.ipify.org', which is a service used to determine the public IP address, or outbound network connections on port 7712 to external IP addresses (excluding common private IP ranges). Both of these activities, especially when combined, can be associated with malicious software like the MonsterV2 C2 framework, which might use such methods for initial reconnaissance or C2 communication.
