NSA, CISA, FBI, and International Partners Release Cybersecurity Advisory on “Fast Flux,” a National

[Kyaw_Myo_Oo]

Dear All,

Many networks have a gap in their defenses for detecting and blocking a malicious technique known as "fast flux." This technique poses a significant threat to national security, enabling malicious cyber actors to consistently evade detection. Malicious cyber actors, including cybercriminals and nation-state actors, use fast flux to obfuscate the locations of malicious servers by rapidly changing Domain Name System (DNS) records. Additionally, they can create resilient, highly available command and control (C2) infrastructure, concealing their subsequent malicious operations. This resilient and fast changing infrastructure makes tracking and blocking malicious activities that use fast flux more difficult.
