A bit before Y2K, cyber threats were already a growing concern for those of us working in IT. I started my career in 1985, working on a VAX 9000 and Wang Desktops, and I vividly remember the early days of cybersecurity risks. The piece on Y2K is very well done but most in the industry today do not remember the release of Windows 95. This origins story can actually benefit by going even further back than Y2K -some of the most significant early security events happened well before 2000. In 1988, the Morris Worm spread across ARPANET, disrupting thousands of computers and leading to the first conviction under the Computer Fraud and Abuse Act. The Michelangelo Virus in 1991 created widespread fear of mass data loss, while the first ransomware attack-the AIDS Trojan-emerged in 1989, demanding a ransom for encrypted files. By 1996, DDoS attacks like the one against Panix demonstrated how hackers could overwhelm networks, and in 1994, a UK-based hacker breached the U.S. Air Force's Rome Laboratory, stealing military research and launching further cyber intrusions. Even the earliest phishing scams began in the mid-1990s, with attackers targeting AOL users to steal passwords. By 1998, organized cybercrime was on the rise with groups like the Russian Business Network, showing that cybercriminal enterprises were already well-established. These events prove that cybersecurity has been an evolving battle for decades, shaping the defenses we rely on today. Understanding these early threats reminds us that while technology advances, so do the tactics of those looking to exploit it.

A fantastic retrospective on cybersecurity's evolution since Y2K! That moment was a wake-up call, shaping the security-conscious world we navigate today. From rudimentary firewalls to AI-driven defense, the shift has been monumental, with cyber-physical systems, IoT, and nation-state threats redefining risk. Looking ahead, quantum computing and AI-powered attacks will demand even greater agility and foresight. Cybersecurity is no longer just about protection-it's about resilience and strategic advantage. Thanks for sharing this insightful piece! How do you see cybersecurity frameworks evolving to meet the next wave of challenges?
