What is the most deadly computer virus and why?

There are many computer viruses that have caused devastation over the years, but there is one in particular that stands out as the most deadly. The WannaCry virus first appeared in May of 2017 and within a matter of days had infected more than 230,000 computers in 150 countries. What made WannaCry so deadly was its use of a leaked NSA hacking tool called “EternalBlue” to spread itself quickly and efficiently. Once a computer was infected, the virus would encrypt all of the files on the hard drive and demand a ransom of $300 in Bitcoin to decrypt them. If the ransom wasn’t paid within three days, the price would double. And if it still wasn’t paid after seven days, the files would be permanently deleted.

While WannaCry didn’t cause as much damage as some other viruses, it was the first major ransomware attack and it proved that ransomware can be an incredibly effective and dangerous tool. WannaCry also highlighted some serious security vulnerabilities that need to be addressed. In the months since the attack, there have been many other ransomware viruses that have caused significant damage, but WannaCry remains the most deadly.
