“Fast Flux” allows Botnets-infected computer networks to constantly change IP addresses and domain names at any time at any hour. This prevents the defenders from calculating and blocking the source of the attack and stabilizes the pirates of the computer. The method has already been used for extortion attacks such as Hive and Nefilim. The NSA can attack banks, energy systems or government agencies because such networks call it a serious threat.
Authorities recommend that companies and special users strengthen the protection: update the software regularly, follow suspicious traffic and use modern antiviruses. Experts say that the rapid flux is not an innovation, but it is underestimated that allowed hackers not to be noticed for years.
