The WannaCry ransomware attack that swept the globe in 2017 left a trail of devastation in its wake, affecting over 200,000 computers in more than 150 countries. The attack, which targeted vulnerabilities in the Windows operating system, encrypted files on infected computers and demanded a ransom in Bitcoin in exchange for the decryption key. But what happens if you pay WannaCry? Does paying the ransom guarantee that your files will be restored, or are you simply throwing money at a problem that may not have a solution?
Understanding WannaCry Ransomware
Before we dive into the consequences of paying the WannaCry ransom, it’s essential to understand how the ransomware works. WannaCry is a type of malware that uses a vulnerability in the Windows operating system to spread from computer to computer. Once a computer is infected, the ransomware encrypts all the files on the system, making them inaccessible to the user. The attackers then demand a ransom in Bitcoin, typically in the range of $300 to $600, in exchange for the decryption key.
How WannaCry Spreads
WannaCry spreads through a vulnerability in the Windows operating system known as EternalBlue. This vulnerability was discovered by the National Security Agency (NSA) and was leaked by the Shadow Brokers hacking group in April 2017. The vulnerability allows attackers to execute arbitrary code on a remote computer, which enables them to spread the ransomware from computer to computer without the need for user interaction.
