In this episode of Reimagining Cyber,  Tyler Moffitt, Senior Security Analyst at OpenText Cybersecurity,  explores the evolution of fast flux — a once obscure spamming tactic that has now become a serious national security concern. Learn how this evasive DNS technique enables ransomware groups and nation-state actors to stay resilient, hide their infrastructure, and extend the life of their attacks.

Tyler breaks down how fast flux works, why it’s seeing renewed attention from the NSA and CISA, and what security teams can do to detect and defend against it. From DNS filtering and anomaly detection to the role of ransomware affiliates and cybercriminal business models, this episode delivers deep insights into one of today’s most pressing cybersecurity threats.

Key topics:

• Fast flux: what it is and why it matters now
• How it's being used to protect ransomware infrastructure and leak sites
• Detection strategies and red flags for defenders
• The bigger picture: national security, affiliate models, and the cybercrime economy
• Practical steps enterprises can take to prepare and protect
