First cyberattack, "Morris Worm," happened in 1988.

In 1988, the world was introduced to a new era of digital threats when the first-ever cyberattack occurred, known as the "Morris Worm." Created by a talented young computer scientist named Robert Tappan Morris, this worm was a harbinger of the cybersecurity challenges that would come to define the digital age. The Morris Worm was not malicious in the traditional sense; instead, it was intended as an experiment. Morris sought to measure the size of the nascent internet by creating a self-replicating program that would propagate across connected computers. However, a critical flaw in the code led to unforeseen consequences, turning what should have been a benign experiment into a significant cybersecurity incident. The worm exploited vulnerabilities in the Unix operating system and spread rapidly across ARPANET, the precursor to today's internet. Its replication mechanism caused infected computers to slow down or crash, disrupting critical network services. The Morris Worm's unintended impact demonstrated the potential for chaos in the digital realm and highlighted the need for cybersecurity measures to protect against such threats. In the aftermath of the Morris Worm incident, Robert Tappan Morris was convicted of violating the Computer Fraud and Abuse Act. His case underscored the legal consequences that could result from unauthorized intrusion into computer systems. More importantly, the Morris Worm marked the dawn of a new era in which individuals and organizations needed to take cybersecurity seriously. It served as a wake-up call, prompting the development of more robust network defenses and paving the way for the cybersecurity industry we know today.
