An interesting fact is that the first computer virus was created in 1983 by a programmer named Fred Cohen as an experiment to demonstrate the potential vulnerabilities in computer systems. He wrote a piece of code designed to self-replicate and spread between computers, which laid the foundation for the concept of malicious software (malware) that continues to evolve to this day. This event marked a pivotal moment in the history of cybersecurity and raised awareness about the need for protective measures against digital threats.
