It allows decentralized networks operated by threat actors to hide their infrastructure and survive takedown attempts that would otherwise succeed. Fast flux works by cycling through a range of IP addresses and domain names that these botnets use to connect to the Internet. In some cases, IPs and domain names change every day or two; in other cases, they change almost hourly. The constant flux complicates the task of isolating the true origin of the infrastructure. It also provides redundancy. By the time defenders block one address or domain, new ones have already been assigned.<\/p>\n<h2>A significant threat<\/h2>\n<p>\u201cThis technique poses a significant threat to national security, enabling malicious cyber actors to consistently evade detection,\u201d the NSA, FBI, and their counterparts from Canada, Australia, and New Zealand <a href=\"https:\/\/www.cisa.gov\/news-events\/cybersecurity-advisories\/aa25-093a\">warned Thursday<\/a>. \u201cMalicious 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.
