In this guest post by 5u IT Services, we look at what ransomware is, how you can protect yourself from it and what you can do if you’re infected.

According to TrendMicro, Ransomware is often spread through emails containing suspicious links. Once clicked, the hackers could get the user’s pc and subsequently their files, which they can freeze and block. That is where they endanger the victim with the loss of the documents, should they deny payment.

But, there are ways that you may spot a dodgy email. Look closely at the email address to find out whether it is valid. Inside the body of the email itself, search for obvious errors and grammatical errors. Furthermore, you may try hovering over hyperlinks (without clicking them) to see if they guide you to dubious web pages.

‘Malvertising’ is a new method that includes the embedding of malware in ads on sites you’re familiar with and trust. They are often pop-ups and sometimes promote applications to eliminate malware. Never click on these adverts, but close the windows instantly. To prevent malvertising appearing on your trusted sites, you can use ad blockers, or alternatively, repair known browser security holes.

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

3. Always install legitimate updates

If you’re a part of a company ensure that you disconnect from the corporate network and the world wide web to avoid malware spreading to other devices. Also disable Wi-Fi and Bluetooth as these may also be an entry for ransomware. Report the crime and seek support from a specialist who participates in data retrieval, so it’s possible to talk about your alternatives. In extreme situations, your only option may be to pay the ransom, however DO NOT do so unless you have spoken to an expert 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.
