Rapid Changes: A Threat to National Security

There is a gap in many networks in detecting and blocking a malicious technique known as 'fast flux'. This technique represents a significant threat to national security, as it allows malicious cyber actors to constantly evade detection. The National Security Agency (NSA), the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), the Australian Signals Directorate's Australian Cyber Security Centre (ASD's ACSC), the Canadian Centre for Cyber Security (CCCS), and the New Zealand National Cyber Security Centre (NCSC-NZ) are issuing a joint warning about the ongoing threat of malicious activities enabled by fast flux as a defensive gap in many networks. This advisory aims to encourage service providers, especially Protective DNS (PDNS) providers, to help mitigate this threat by taking proactive steps to develop accurate, reliable, and timely fast flux detection and blocking capabilities for their customers. Additionally, our company Q2BSTUDIO specializes in technology development and services to contribute to the detection and mitigation of malicious activities such as fast flux.
