Description​

AlphaSOC detected network traffic to a destination under a top-level domain (TLD) commonly associated with malware, phishing, or command and control (C2) communications.

Impact​

Traffic to suspicious TLDs may indicate a successful malware infection or ongoing compromise attempts. Threat actors often leverage uncommon or newly introduced TLDs to host malicious infrastructure because these domains are typically cheaper and less scrutinized.
