On Friday, May 12, 2017, and over the following weekend, a ransomware attack hit a number of global companies and domestic institutions with malicious software known as WannaCry, or WannaCrypt.
This ransomware encrypts data files and asks users to pay ransom in bitcoins under the threat of deleting data if the ransom is not paid.
The malware is known as WannaCry, WannaCrypt, WCRY, WanaCrypt0r, WeCry, WeCrypt0r, or Wanna Decryptor.
It works in the way that it exploits Windows OS vulnerabilities discovered by the NSA and then stolen by a group of hackers calling themselves “Shadow Brokers”. The versions of Windows operating systems affected are all except Windows 10.
In order to protect against this malware, ensure your OS is up to date, and install security software like Norton Security or alike.
