U.S. agencies issue a joint cybersecurity advisory warning about the threat of 'fast flux' attacks.
'Fast flux' is a technique used by cybercriminals to rapidly change Domain Name System (DNS) records to obscure the locations of their malicious servers.
This technique poses challenges to detection and mitigation efforts as it exploits the dependency on DNS infrastructure.
Mitigation strategies include DNS and IP blocking, sinkholing, reputational filtering, enhanced monitoring, and collaboration with trusted partners.
