Stories from the history of cyber attacks. Lessons for the future.

The internet runs on trust.

Every day, billions of systems exchange data, process transactions, and store information we depend on. But history has shown how fragile that trust can be.

A missed patch.
A stolen credential.
A vulnerability no one noticed.

Chronicles of Compromise documents the cyber attacks that exposed those weaknesses. Each story explores the timeline, the techniques, and the people behind some of the most significant breaches in modern history.

Understanding how these attacks happened is more than curiosity.

It’s how we learn to stop the next one.

  • NotPetya: The Cyber Attack That Wasn’t Ransomware
    On June 27, 2017, the NotPetya cyber attack began in Ukraine, initially appearing as ransomware but ultimately functioning as wiper malware, aimed at destroying systems. Spreading globally, it disrupted major companies and caused over $10 billion in damages. The attack highlighted vulnerabilities in supply chains and the geopolitical implications of cyber warfare.
  • The Day the Internet Held Its Breath: The WannaCry Ransomware Attack
    On May 12, 2017, the WannaCry ransomware attack rapidly infected over 300,000 computers worldwide, affecting critical systems like hospitals and manufacturing plants. Exploiting a Microsoft Windows vulnerability known as EternalBlue, it demanded a ransom in Bitcoin. Cybersecurity weaknesses were exposed, prompting global reforms to enhance digital resilience and address vulnerabilities.
