How does the world’s most deadly computer virus work?
The world’s most deadly computer virus is called the “WannaCry” virus, and it is a type of ransomware. Ransomware is a type of malware that encrypts a victim’s files and demands a ransom be paid in order to decrypt them. WannaCry is particularly dangerous because it uses a vulnerability in Microsoft Windows to spread itself quickly and easily. Once a computer is infected with WannaCry, it will scan the victim’s network for other vulnerable computers and infect them as well. The virus then displays a message on the victim’s screen, demanding a ransom be paid in order to decrypt their files. The ransom must be paid in Bitcoin, and the amount varies depending on how quickly the victim responds. If the ransom is not paid within a certain amount of time, the amount doubles. WannaCry has been responsible for some of the largest and most costly ransomware attacks in history, causing billions of dollars in damage.
What is the difference between a computer virus and a computer worm?
A computer virus is a malicious code that attaches itself to files and programs, overwriting and corrupting them. A virus needs human intervention to spread, for example, by duping a user into clicking on an email attachment that installs the virus. A worm, on the other hand, is a self-replicating malware that can spread itself to other computers without human intervention. A worm exploits security holes to enter a system and then copies itself to other computers on the same network.
