Cyberthreats and attacks have been a negative side effect of our computer age for more than three decades. The first viruses or worms were less harmful, designed to slow a system down or annoy other users. Some even say the first viruses were designed as practical jokes. In 1986, the first malicious virus was discovered. The Brain virus, one of the earliest forms of ransomware (though its creators would remove it for free), went worldwide over a short period of time.
