What is WanaCrypt0r 2.0 Ransomware?

What is WanaCrypt0r 2.0 Ransom and why is it attacking the NHS?

A massive global cyberattack began today and has infected a number of high profile organisations around the world, including the NHS National Health Service in the UK.

The attack is caused by an unpleasant type of malware called “ransomware”, which has spread to many computers around the world via email distributed over networks. The malware denies access to data and keeps it safe until Bitcoin pays for it.

WanaCrypt0r 2.0 hit NHS in the UK, forcing hospitals to redirect patients from ambulance wards, Telefonica in Spain and computers in Russia, Ukraine and Taiwan, leaving computers and information locked up for ransom.

What is ransom software?

Ransomware is a type of malware that denies access to a computer or its data and requires a ransom (money for release).

How does ransom software work?

When a computer is infected with a ransom demand, it connects to a server to activate itself, then begins encrypting data from the infected computer and sends it to a server. Once all files are encrypted, a message will appear on your computer asking you to make a payment to decrypt the files – and threatening to delete the data if it is not paid. In most cases, a timer is used to increase the urgency.

It is also known as Wanna Decryptor 2.0, WCry 2, WannaCry 2 and Wanna Decryptor 2.

How much redemption do they ask for?
WanaCrypt0r 2.0 requires 0.1 Bitcoin (about $177) to unlock the contents of your computers.
