Ransomware

What Is Ransomware?

Ransomware is a type of malicious software (malware) that is designed to block access to a computer system or data until a ransom is paid. It is typically spread through phishing emails, malicious websites, or other online sources. Once installed, ransomware encrypts the user's data and locks them out of their system, preventing them from accessing their files or programs. The attacker then demands a ransom payment in exchange for the decryption key, which is necessary to regain access to the system and data. Ransomware attacks can be financially devastating for individuals and organizations, as they can result in the loss of important data and the disruption of business operations.

Usage and Examples

Ransomware is typically spread through phishing emails, malicious websites, or other online sources. Once installed, ransomware encrypts the user's data and locks them out of their system, preventing them from accessing their files or programs. The attacker then demands a ransom payment in exchange for the decryption key, which is necessary to regain access to the system and data. Ransomware attacks can be financially devastating for individuals and organizations, as they can result in the loss of important data and the disruption of business operations.

For example, in 2017, the WannaCry ransomware attack affected more than 200,000 computers in over 150 countries, resulting in billions of dollars in losses. In 2019, the Ryuk ransomware attack targeted more than 200 organizations, including hospitals, universities, and government agencies, resulting in millions of dollars in losses.
