The companies and people who have been affected by the most dangerous computer virus of all time.

When it comes to computer viruses, there is one that stands above the rest as the most dangerous of them all. That virus is known as WannaCry, and it has caused havoc for companies and individuals around the world.

WannaCry is a ransomware virus that first emerged in May of 2017. The virus quickly spread around the globe, affecting hundreds of thousands of computer systems. The virus encrypted data on infected computers and demanded a ransom be paid in order to decrypt the data.

Many companies and individuals paid the ransom, but there was no guarantee that the data would be decrypted even if the ransom was paid. As a result, many companies and individuals lost important data and files that they could never get back.

WannaCry caused major disruptions for companies, especially those in the healthcare sector. Hospitals were forced to cancel appointments and turn away patients because they could not access their systems. In some cases, life-saving surgery was postponed because of the virus.

Companies in other industries were also affected. Railway systems were disrupted, factories were shut down, and ATMs stopped working. The virus even caused problems for the UK’s National Health Service (NHS).

The WannaCry virus was eventually stopped by a security researcher who found and activated a “kill switch” in the virus’ code. However, the damage had already been done.

The WannaCry virus was the most dangerous computer virus of all time because of the widespread damage it caused and the number of people and companies affected. It is a prime example of how a single virus can cause havoc on a global scale..Read Full Report

The Morris Worm

The Morris worm is considered to be one of the first major computer viruses. It was created in 1988 by a graduate student named Robert Morris. The worm was designed to propagate itself across the internet and infect as many computers as possible.

While the Morris worm did not cause any direct damage to computers, it did cause a great deal of inconvenience. The worm overloaded servers and caused widespread internet outages. It is estimated that the Morris worm caused over $100 million in damages.

The ILOVEYOU Virus

The ILOVEYOU virus is a malware that was released in 2000. The virus was spread via email attachments that appeared to be love letters. Once opened, the attachment would send itself to everyone in the victim’s address book.

The Code Red Worm

The Code Red worm was released in 2001 and quickly spread across the internet. The worm took advantage of a buffer overflow vulnerability in Microsoft’s IIS web server software. Once a computer was infected, the worm would attempt to spread itself to other computers.

The Code Red worm caused over $2 billion in damages and was responsible for bringing down several major websites, including those of Microsoft and Yahoo.

The Slammer Worm

The Slammer worm was released in 2003 and quickly spread across the internet. The worm took advantage of a buffer overflow vulnerability in Microsoft’s SQL Server software. Once a computer was infected, the worm would attempt to spread itself to other computers.

The Slammer worm caused over $1 billion in damages and caused a major outage of the internet. The worm also caused problems for ATMs, hospital systems, and air traffic control systems.

The SQLSlammer Worm

The SQLSlammer worm was a variant of the Slammer worm that was released in early 2003. The worm took advantage of the same buffer overflow vulnerability in Microsoft’s SQL Server software. Once a computer was infected, the worm would attempt to spread itself to other computers.

The SQLSlammer worm caused over $1 billion in damages and was responsible for bringing down several major websites, including those of Microsoft and Yahoo.

The Blaster Worm

The Blaster worm was released in 2003 and quickly spread across the internet. The worm took advantage of a vulnerability in Microsoft’s Remote Desktop Protocol (RDP). Once a computer was infected, the worm would attempt to spread itself to other computers.

The Blaster worm caused over $1 billion in damages and was responsible for bringing down several major websites, including those of Microsoft and Yahoo.

The Mydoom Worm

The Mydoom worm was released in 2004 and quickly spread across the internet. The worm took advantage of a buffer overflow vulnerability in the email software Microsoft Outlook. Once a computer was infected, the worm would attempt to spread itself to other computers.

The Mydoom worm caused over $1 billion in damages and was responsible for bringing down several major websites, including those of Microsoft and Yahoo.

The WannaCry Ransomware

The WannaCry ransomware was released in 2017 and quickly spread across the internet. The ransomware took advantage of a vulnerability in Microsoft’s Windows operating system. Once a computer was infected, the ransomware would encrypt the user’s files and demand a ransom for the decryption key.

The WannaCry ransomware caused over $4 billion in damages and affected over 200,000 computers in 150 countries. The ransomware was particularly damaging to the UK’s National Health Service (NHS) where it caused a great deal of disruption.
