That is where they threaten the victim with the reduction of the documents, should they refuse payment.

However, there are ways that you may spot a dodgy email. Look carefully at the email address to see if it’s valid.

By backing all of your data onto external drives that aren’t directly connected to a desktop system, however, would allow you to erase all information from the attacked device and restore it using the backup, in the event you fall prey.

What do I do if I’m already infected?

If you’re part of a business make sure you disconnect from the corporate community and the internet to steer clear of malware spreading to other apparatus. Also disable Wi-Fi and Bluetooth since these may also be an entry for ransomware. Report the offense and seek support from a specialist who majors in data retrieval, which means you can talk about your options. In extreme situations, your only option is to pay the ransom, however DO NOT do so unless you’ve spoken to a professional first.

For businesses, Ransomware is an absolute nightmare and can run riot through a network. For that reason, we’d always suggest ensuring that you have adequate security patches installed as well as robust antivirus and firewall solutions in place.
