Ransomware is a type of malware that locks the victim’s computer data basically by encrypting the data. Before granting access to the data a demand is made to make the payment to decrypt the data. Unlike other cyber attacks, the victim is notified after their system is infected. The purpose of the attack nearly always money.
Ransomware can enter into your system through an infected website or an external hard drive. It can enter through email attachment. Or they may use other option which does not require interaction. The payment is always demanded by a virtual currency so that the identity of the hacker remains hidden
