History Of Computer Viruses 1989 1999



History of​ Computer Viruses since 1989-1999
Robert Morris’s Internet Worm of​ 1988 was the​ biggest news in​ virus history for several years .​
Until 1992,​ most virus news was much quieter.
In 1989,​ for example,​ Ghostball was released .​
This was the​ first virus able to​ attack different kinds of​ targets .​
Before Ghostball,​ viruses were classified by their attack,​ like file infector or​ boot sector virus .​
Ghostball was the​ first Multipartite virus,​ because it​ could follow several attack patterns.
In 1990,​ a​ programmer named Mark Washburn demonstrated a​ Polymorphic virus.called 1260 .​
This virus could actually change the​ structure of​ it’s own code—meaning,​ every time it​ infected a​ new system,​ it​ looked different while doing the​ same thing .​
In effect,​ this kind of​ virus hides from anti-virus software by wearing disguises.
Michelangelo was the​ first virus to​ achieve stardom .​
It was discovered in​ 1991,​ and was predicted to​ cause incredible amounts of​ damage when it​ reached it’s trigger date,​ March 6th,​ 1992 (March 6th is​ Michelangelo’s birthday) .​
If an​ infected system is​ booted on​ March 6th,​ the​ virus will erase the​ hard drive .​
Despite doomsday warnings made by the​ press and the​ antivirus industry of​ at​ least five million infected systems at​ risk,​ only about 10,​000-20,​000 computers worldwide were hit by the​ virus.
The Concept virus was discovered in​ 1995 .​
Concept is​ short for Proof of​ Concept,​ and it​ was designed to​ show how viruses could be written in​ the​ macro language programmed into Microsoft Word .​
By 2004,​ roughly 75% of​ all viruses are macro viruses.
The CIH virus,​ later renamed Chernobyl,​ appeared in​ 1998 .​
This was a​ very damaging virus that was not only programmed to​ erase hard drives but also tried to​ erase BIOS chips .​
For the​ first time in​ history,​ a​ virus had managed to​ actually damage the​ hardware it​ was running on​ .​
Fortunately,​ CIH wasn’t very good at​ it,​ and only damaged a​ handful of​ systems.
