A full guide of Ransomware Attack Prevention

SaferTech Description: Selma turned on her computer, waited while it booted up, and then saw this. It was a ransomware message. Cybercriminals had got access to her computer and infected it with malware which effectively locked her files and meant that she couldn’t use them. The message said that if she wanted to unlock the files, she’d have to pay a fee, in other words a ransom, and then she’d be sent a ‘key’ to unlock them. Compared to the disruption that the loss would cause, the amount of money being demanded wasn’t that much and she wasn’t sure what to do.

In most cases, it’s best to set the software to do this automatically when an update is released. Next, regularly back up your data to an external drive or to a cloud based system. Do this, so that you have an alternative way to access your files if they were locked.

The more valuable your data is to you, the more frequently you should back it up. Be cautious. Many ransomware attacks start with phishing emails and as these are getting more and more sophisticated, be careful before clicking on any links, or opening any attachments, in the emails you receive. Criminals also create web ads that are designed to make us curious, or feel that we’re missing out on something, and they also play on our emotions in order to get us to click, or tap, on malicious links.
