- Fast flux is a technique used by hostile nation-states and ransomware groups to hide their operations.
- It cycles through IP addresses and domain names, making it hard to trace the true origin of the infrastructure.
- The technique provides redundancy, allowing new addresses to be assigned quickly if one is blocked.
- Fast flux is a significant threat to national security, enabling cybercriminals and nation-state actors to evade detection.
- Wildcard DNS records are a key means for achieving fast flux, mapping non-existent subdomains to attacker IPs.
