Ransomware Attack is a type of malicious software that can infect a computer system by blocking access to the stored data by encrypting the files.

The perpetrator then demands ransom from the owner in exchange for the decryption key.

Modus operadi: The malicious software (virus) may have been injected remotely by tricking the user into downloading it upon clicking an relatively safe-looking web link sent via email or other means.

The virus may have then spread throughout the network by exploiting existing vulnerabilities.
