Quantum computing is often described as a distant, abstract threat — something that will matter "someday". But for Cyber Threat Intelligence Teams, the implications are already taking shape. Cryptographic transitions, long-term data sensitivity, and adversary capability forecating are becoming strategic priorities, not theoretical discussions.
Across this series, I'll examine how CTI practitioners can understand, anticipate, and prepare for quantum‑driven changes in the threat landscape. Topics include:
- Why CTI still matters in a post‑quantum world
- "Harvest Now, Decrypt Later" and long‑term adversary collection
- What CTI teams can do today to prepare for quantum risk
- How threat actors may adapt during the PQC transition
- Quantum capability forecasting
- The CTI role in cryptographic migration
- Sector‑specific quantum exposure
- Transitional threats and new attack surfaces
My goal is to provide clear, structured, and practical analysis for practitioners who want to think beyond the hype and understand what quantum change really means for intelligence work.
This is the starting point. Each article will build on the last, forming a complete picture of how CTI evolves in the post‑quantum era.
