Ransomware is a type of malware that encrypts a victim's files, rendering them inaccessible until a ransom is paid to the attacker to restore access. The ransom is typically demanded in the form of cryptocurrency, such as Bitcoin, in order to maintain the anonymity of the attacker.
Ransomware attacks can be particularly devastating for individuals and organizations, as they can result in the loss of important data and disruption of business operations. In some cases, victims may be unable to recover their data even if the ransom is paid, as there is no guarantee that the attacker will actually restore access to the files.
There are several types of ransomware, including:
Cryptojacking ransomware: This type of ransomware uses the victim's computer resources to mine cryptocurrency for the attacker.
Encrypting ransomware: This type of ransomware encrypts the victim's files and demands a ransom in exchange for the decryption key.
Locker ransomware: This type of ransomware locks the victim out of their computer or device and demands a ransom in order to restore access.
Ransomware-as-a-service: This type of ransomware is offered as a service to other attackers, who can use it to carry out ransomware attacks on their own.
One well-known example of ransomware is the WannaCry attack, which affected thousands of organizations and individuals in 2017. The WannaCry ransomware encrypted victims' files and demanded a ransom of $300 in Bitcoin in order to restore access.
Overall, ransomware is a serious threat to individuals and organizations, and can result in significant financial and operational losses. It is important to take measures to protect against ransomware, such as keeping software and security systems up to date and regularly backing up data.
