RANSOMWARE AND CRYPTO-VIRUSES

Ransomware and Crypto-Viruses are types of malware that encrypt the data of a compromised system without the approval of a company. The longer the viruses run the more data they encrypt. The viruses are built with information on how to send ransom money and increase the amount demanded at regular intervals.

These viruses can quickly shut down entire companies and lock entire drives of data Ransomware and Crypto-Viruses are commonly acquired by clicking on viral links on the web, downloading an infected installer, or opening and infected attachment from an email.

The malware then attacks anything that the account that has been affected has access to, including network shares, local drives and remote drives.
