It’s all started in the month of April when a group called “The Shadow Brokers” stole documents and tools which the NSA (National Security Agency) from the United States used by the name of “EternalBlue” to spy on computers around the world. Many cyber security experts also accept that this virus is a developer tool run by the NSA. Further, these hackers turned those stolen tools into a RansomWare software.

Who are those hackers? That’s still a mystery. Eventually, this RansomWare turned into WanaCryptor 2.0, which is also known as WCry, WannaCry, WannaCrypt, Wana Decrypt0r.

WannaCryptor 2.0 first encrypts your files, as a result, it will demand a ransom. In order you to get your files back, they ask for a minimum of 300$ to 800$. The terrifying thing is that the software will give you 7 days to pay your ransom, otherwise, your data will be lost forever.

There are a number of file types that WannaCryptor has targeted. From .123 to .zip, they cover almost all important file types. This virus is hidden in the form of a document or PDF file which travels from one computer to another.

They also leave a text file note on a user desktop with the messages like:

“oopps! your important files are encrypted.”

“If you follow our instructions, we guarantee you that you can decrypt all your files quickly and easily”

“Please send 300$ worth of bitcoins to this bitcoin address”

WannaCryptor attacks on some of the prominent organizations, including NHS in Britain, Telefonica in Spain and Russian interior ministry. It is been claimed that this virus has some hidden links with North Korea. It is also been reported that this virus also reaches to Pakistani computers probably in Islamabad, but due to  Malware tech, the attack did not hit so hard on Pakistan.

There are also some reports that claim there are many computers under the Shaukat Khanum Memorial Hospital which have also been reported under this threat. Due to the efforts of US security agencies, the threat of these attacks have slowed down but they still have the potential to shut your computers down.
