Executive summary
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.
The National Security Agency (NSA), Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC), Canadian Centre for Cyber Security (CCCS), and New Zealand National Cyber Security Centre (NCSC-NZ) are releasing this joint cybersecurity advisory (CSA) to warn organizations, Internet service providers (ISPs), and cybersecurity service providers of the ongoing threat of fast flux enabled malicious activities as a defensive gap in many networks. This advisory is meant 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 analytics and blocking capabilities for their customers. This CSA also provides guidance on detecting and mitigating elements of

Note: Canada’s propane exports to the Pacific Basin include three shipments to Hawaii, according to Vortexa (less than 200,000 barrels each in 2021, 2023, and 2024).
Canada’s propane exports have steadily increased over the last decade, reaching record highs in 2024 as new marine export terminals streamlined the flow of propane from western Canada to export destinations, particularly to Asia. U.S. propane imports from Canada have stayed relatively consistent since Canada began waterborne exports in 2019.
Propane spot prices in Edmonton, Alberta, are typically at a discount to prices in both East Asia and Conway, Kansas, the propane market hub for the Midwest. Competitive pricing in Canada underpins the demand for Canada’s propane in both East Asia’s and the
