Ransomware is a variant of cyber-attack that involves hackers taking over a computer or other device and insisting payment. Many ransomware strikes are targeted toward businesses and big businesses, but it can also affect individuals.

There are many ways to safeguard yourself from ransomware, and many attacks could have been averted had the victim exercised care in their everyday usage of their devices. Security specialists have introduced tips to help users protect themselves from these cyber-attacks, especially after a rise in national and international cases:

1. Be wary of emails, pop-ups and anti virus apps

According to TrendMicro, Ransomware can be spread through emails containing suspicious links. Once clicked, the hackers can access the user’s pc and then their files, which they can freeze and block. That is where they threaten the victim with the reduction of their files, should they refuse payment.

But, there are ways you can spot a dodgy email. Look closely at the email address to find out if it is valid. Furthermore, you could try hovering over links (without clicking them) to see if they guide you to suspicious web pages.

Do not forget that banks and credit card companies will never request private information including your password or credit card details.

‘Malvertising’ is a brand new method which 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 remove malware. Never click on those adverts, but shut the windows instantly. To stop malvertising appearing in your trusted websites, you can use ad blockers, or rather, fix known browser security holes.

Lastly, never download an app that has not been certified by an official shop, and always read reviews before installing anything to avoid allowing attackers access to your personal computer or mobile device.

By backing all of your data onto external drives that are not directly connected to a desktop system, however, would let you erase all information from the attacked device and restore it with the backup, should you fall prey.

3. Always install valid updates

Upgrades are often released to fix bugs which may make your device more vulnerable to ransomware along with other attacks. Therefore, download the newest version of your software whenever it becomes available. To ensure you know when updates are available, turn on alarms or configure your devices to automatically install the newest updates.

4. Install an antivirus program

Antivirus software can detect malware and prevent it from infecting your pc before it will become visible or a threat for you. Nonetheless, be sure that you only download these software from respectable companies like Bitdefender, Kaspersky Lab, and Norton.

5. Never pay the ransom

Paying the ransom will sadly only encourage attackers further, and there is no guarantee your files will be recovered. Should you back up your information regularly, however, you can restore your files from that.

If you’re part of a business ensure you disconnect from the corporate community and the internet to steer clear of malware spreading to other devices. Also disable Bluetooth and Wi-Fi as these may also be an entrance for ransomware. Report the offense and seek support from a specialist who majors in data retrieval, so it’s possible to discuss your options. In extreme situations, your only option may be to pay the ransom, but DO NOT do this unless you have 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.
