Don't Get Caught in the Flux: DNS Back in the Spotlight with the Fast Flux Threat

 


Imagine a world where you have to remember dozens of number combinations just to access your favorite websites. Luckily, the Domain Name System (DNS) translates domain names into IP addresses, making it easy to navigate the internet. However, DNS is also a prime target for cybercriminals, with threats like DNS spoofing, amplification attacks, and the latest Fast Flux DNS tactic. This week, CISA issued a warning about Fast Flux DNS, a sneaky tactic used by cybercriminals to stay hidden and resilient. In this video, we'll break down what Fast Flux DNS is (single and double flux), how attackers constantly rotate IP addresses and name servers to evade detection, and most importantly, how you can protect your DNS systems from these threats. Learn how Plixer One’s Observability & Defense Platform helps you detect and stop DNS abuse fast. So yeah, you don’t have to give a flux… but you kinda should.
