WannaCry Ransomware


What is WannaCry Ransomware?

WannaCry Ransomware is a type of malicious software that encrypts a user’s files, making them inaccessible unless a ransom is paid. It was first discovered in May 2017 and spread rapidly, affecting more than 200,000 computers around the world. The ransomware is believed to have originated from the shadowy hacker group, the Shadow Brokers, who obtained the ransomware code from the National Security Agency.

Once a computer is infected with WannaCry, it will display a message demanding the user pay a ransom in the form of Bitcoin in order to regain access to their files. The ransom amount is typically between $300 and $600, but it can increase if the user does not pay within a certain amount of time. The ransomware has been used to target individuals, businesses, and government organizations, so it is important to take measures to protect yourself from this type of attack. These measures include updating your computer regularly, running anti-virus software, and backing up your data.

FedEx attack: In May 2017, the global delivery company, FedEx, was among the organizations affected by the WannaCry attack. The ransomware caused significant disruptions to the company's operations and resulted in a significant financial loss.

Simplified Example

Just like a thief breaking into a home and holding valuable possessions for ransom, WannaCry takes control of a victim's computer files and demands payment for their release. If the victim does not pay the ransom, their files will remain encrypted and inaccessible for the end user.
