The most dangerous computer virus ever: the story of the Love Letter virus

On May 4, 2000, a new virus began making its way around the world, causing millions of dollars in damage. The Love Letter virus, also known as the ILOVEYOU virus, was one of the most destructive viruses of all time.

The Love Letter virus was spread via email. It would come in an email with the subject line “ILOVEYOU” and the body of the email would say “Hi, I love you,” followed by a file attachment. The attachment was usually a .vbs file, which is a type of scripting file.

When the Love Letter virus was opened, it would copy itself to all of the victim’s contact files. It would then send itself out to everyone in those contact files. As the virus spread, it would also overwrite files on the victim’s computer with copies of itself.

The Love Letter virus caused an estimated $10 billion in damage. It affected governments, businesses, and individuals. In the Philippines, the virus caused so much damage that the government had to shut down its email system.

The Love Letter virus was created by two Filipino programming students, Onel de Guzman and Reonel Ramones. They said that they created the virus as a prank and did not intend for it to cause so much damage.

While the Love Letter virus was certainly destructive, there have been other viruses that have caused even more damage. In 2017, the WannaCry virus infected more than 230,000 computers in 150 countries, causing an estimated $4 billion in damage..Citation

The most dangerous computer virus ever: the story of the Nimda virus

On September 18, 2001, a new computer virus began circulating on the Internet. This virus, called Nimda (pronounced “nim-duh”), quickly became one of the most widespread and destructive viruses in history.

Nimda was a so-called “polymorphic” virus, meaning that it could change its appearance to evade detection by anti-virus software. It was also a “multipartite” virus, meaning that it could infect both files and boot sectors. This made Nimda particularly difficult to remove.

Nimda was spread in a variety of ways. It could be transmitted via email, shared networks, and even by simply visiting an infected website. Once a computer was infected, Nimda would replicate itself and spread to other computers on the same network.

The virus caused a great deal of damage. It disrupted business and personal activities worldwide, and cost businesses an estimated $6 billion in damages.

Nimda was also notable for its ability to spread so quickly. Within 24 hours of its release, Nimda had infected an estimated 6 million computers worldwide.

Today, computer viruses are more common than ever. However, none have come close to causing the same level of damage as Nimda.
