DGAs: How Domain Generation Algorithms Power Malware

The report explains how malware and ransomware rely on command-and-control (C2) channels—ranging from hard-coded IPs/hostnames to fast-flux, P2P, Tor, and domain generation algorithms (DGAs)—to receive instructions and exfiltrate data. It highlights DGAs as time- and seed-based algorithms that generate large lists of domains, complicating takedown efforts, and notes that MalwarePatrol tracks DGA seeds and offers threat data feeds and blocklists to help organizations defend against these threats.
