Suspicious VPN Domain or IP Access
This rule detects network connections to suspicious domains or IP addresses associated with potentially compromised or malicious VPN infrastructure. Specifically, it looks for connections to 'vpn-fortinet.com', 'ivanti-vpn.org', 'forticlient-vpn.de', or the IP address '194.76.226.93'. These indicators may suggest attempts to establish command and control, exfiltrate data, or engage in other malicious activities via compromised VPN services.
