What is the most dangerous computer virus ever created?
There are many contenders for the most dangerous virus ever created. However, the following five viruses are some of the most notable and destructive.
1. ILOVEYOU
Created in the Philippines in 2000, the ILOVEYOU virus quickly spread around the world, infecting more than 50 million computers and causing an estimated $5.5 billion in damage. The virus was disguised as a love letter, tricking victims into opening it and releasing the malware onto their system. Once infected, the virus would propagate itself by emailing all contacts in the victim’s address book. The ILOVEYOU virus was particularly destructive as it overwrote critical system files, making it difficult to recover from.
2. Code Red
Code Red was a worm that infected Windows servers in 2001. The worm was notable for its speed and destructive payload. Code Red was designed to spread quickly and efficiently, and it did just that, infecting more than 359,000 systems within 14 hours of its release. The worm also had a destructive payload, which overwrote certain system files and caused the affected system to crash. Code Red was eventually neutralized by a security patch from Microsoft.
3. Sasser
Sasser was a worm that targeted Windows computers in 2004. The worm was notable for its simplicity and the fact that it did not require any user interaction to spread. Sasser would exploit a vulnerability in the Windows operating system and then proceed to spread itself to other vulnerable computers. Once infected, the worm would launch a denial of service attack, crashing the affected system. Sasser was eventually neutralized by a security patch from Microsoft.
4. Conficker
Conficker was a worm that targeted Microsoft Windows computers in 2008. The worm was notable for its ability to spread quickly and its resilience to attempts to neutralize it. Conficker was designed to take advantage of a vulnerability in the Windows operating system, and it did just that, infecting millions of computers within a few days of its release. The worm was also difficult to remove, as it would disable security software and prevent computers from accessing security websites. Conficker was eventually neutralized by a joint effort from security researchers and Microsoft.
5. WannaCry
WannaCry was a ransomware virus that targeted Microsoft Windows computers in 2017. The virus was notable for its destructive payload and the fact that it spread quickly and efficiently. WannaCry exploited a vulnerability in the Windows operating system, allowing it to spread rapidly to other computers. Once infected, the virus would encrypt the victim’s files and demand a ransom for the decryption key. The WannaCry virus caused an estimated $4 billion in damage and infected more than 200,000 computers in 150 countries.
