Domain Generation Algorithm (DGA) Attacks: Understanding, Mitigating, and Defending
Domain Generation Algorithm (DGA) attacks involve the use of algorithms to create numerous, often random-looking, domain names. These generated domains allow malware to connect to its C&C servers, keeping malicious activities in motion even as individual domains are blocked or taken down. By consistently creating new domains, DGA-based malware increases its resilience, complicates detection, and challenges security defences.
