What is ransomware?
Ransomware is a type of malware that invades a company's devices and steals its data and information. Unlike other attackers, this virus does not disclose the company's data. It acts like kidnappers demanding a ransom in exchange for the information.
The hijacker virus encrypts the operating system's data so that its owners no longer have access to it. The action is carried out in the background, without anyone noticing.
Once the hacker has all the data in hand, the company's computer receives a pop-up notification informing it that the machine is blocked and will no longer be usable until the "ransom" is paid. Generally, the amount demanded by criminals must be paid in virtual currency (bitcoin), as this makes it difficult to track who is receiving the money.

In March 2017, the company developed a fix for the system errors, which was still supported. However, those who did not install the program became a target of ransomware attacks.
WannaCry took advantage of this security flaw to encrypt files on computers and prevent their owners from accessing them. It then sent notifications demanding a ransom of $300 in bitcoins, which had to be paid within three days; otherwise, the price would double and the data could be erased.
