North Korea within Data

An Open-Source Analysis of the DPRK's Cyberspace

North Korea's digital world was never meant to be observed, yet it leaves traces. This book rebuilds the structure of the DPRK's cyberspace using only open sources: name-server records, internet routing data, court filings, sanctions designations, patents, and reverse-engineered software.

Instead of threat narratives, it offers a systematic, evidence-based reference on how North Korea's networks are built, connected, and used.

Iran War 2026

The War within Data

A war is also a dataset. Beginning with the U.S.–Israeli strikes on Iran on 28 February 2026, this volume traces the conflict through verified figures — military operations, the Strait of Hormuz closure, and the energy shock that followed — rather than through headlines or verdicts.

Two interpretive essays close the book, asking why the same war keeps returning under different names. Data reflects sources available as of late April 2026.

  • Strike & intercept timelines
  • Strait of Hormuz disruption
  • Energy market impact
  • Verified open sources

North Korea

Defense Science and Technology Perspectives

North Korea's military modernization is increasingly driven not by conventional force but by science, technology, and asymmetric capability. This volume looks past political rhetoric to the laboratories, launch sites, computer networks, and cyber units behind Pyongyang's strategic ambitions.

It covers the space program and its satellite launch vehicles, the dual-use ambiguity of these technologies, and the DPRK's digital and cyber capabilities — a technically grounded contribution to English-language analysis of North Korea.
