Allow us to begin our excursion with Morris Worm or the "Incomparable Worm", which is accepted to be the trailblazer among PC worms dispersed through the web. Made to feature security blemishes in Unix frameworks, its organizer Robert Morris, made a lethal blunder that changed the worm from a possibly innocuous programming to a disavowal of-administration (DDoS) assault machine.
The worm should find out if there was at that point a duplicate running on the PC however rather it just consistently made duplicates of itself, dialing the framework back. At long last, it caused crashes and made the PC totally pointless.
It's accepted that Morris Worm tainted around 6,000 significant Unix machines, causing up to ten million US dollars of harm.
