Very recently, the entire computer world was infected by a ransomware known as WannaCry, Wcry or WannaCrypt. Business corporations, government offices, hospitals, schools and private computers were rendered unusable because of the attack. WannaCry disables computers by encrypting the user’s files. And then the Wcry asks the for a $300 ransom to restore the files. It even doubles the ransom after 6 hours!

Researchers have found the ransomware in computers. Many fell into the deception and victims paid the $300 ransom. The culprit has amassed around $18,000.

It was a good thing, a 22-year old security researcher (@malwaretechblog on Twitter) has stopped the ransomware from spreading further by hitting its ‘kill switch’.WannaCry connects to a randomly typed domain for some reason. When this fails, it continuous to run. The researcher simply registered this domain name leading to a decrease in infected computers.

But the ransomware can still be restarted. Computers running on Windows XP, Windows 8, Windows Server 2003, and older version of windows are vulnerable. Microsoft has already issued a patch to protect these computers from WannaCry and similar exploits.

Simply follow Microsoft’s guide on how to prevent the infection here. Thankfully, the latest OS like Windows 10 is not vulnerable to the ransomware.
