How-to: stay clear of ransomware

There was a lot of attention to ransomware during the summer of 2017, and many companies across the globe were affected by WannaCry, Petya, Goldeneye and NotPetya. As cloud service provider we believe it is our duty to help you prevent ransomware, and also guide you if you are attacked. In this article we will give you four tips on how-to stay clear of ransomware and other malware.

Always pay attention and be critical, especially of the e-mails you receive with attached files. This is how ransomware often spread, and sometimes from seemingly reliable sources. This is why we think the first step to preventing ransomware is to backup your data, getting a backup copy can save you a lot of grieve. When you have an offsite backup you’ll always be able to recreate your lost or infected data from the remote copy. This way you won’t have to pay ransom.

The four steps to avoid ransomware

 

1 – Update your backup on a regular basis

Not only is it important to keep your backup updated you have to test it too. Backup is the number one precaution when it comes to cyber-attacks. Moreover, it’s a good idea to live by the 3-2-1 rule. Having 3 copies, stored in 2 different ways and 1 remote copy.

2 – Update your software

Ransomware can exploit un-updated software to access your computer. Making sure to update software regularly can go a long way. Updating to the newest Windows version and remembering software like Java and Adobe Flash. If you do not use these programs, we recommend you uninstall them.

3 – Use security software

You can also use security software to stop ransomware. Protecting yourself with more than one layer can prove to be beneficial. Security software like:
– Spam- and antivirus filters
– Advance threat protection for e-mail
– Protection for networks like firewalls with application control

4 – Watch out for spam and phishing e-mails

Be critical of attachments in the mails you receive, also if it’s from someone you know like a customer or a colleague. Hover with the mouse to get more information on the attached files. Don’t click or download until you can see what kind of file it is. Watch out for ZIP-files, and remember Word or Excel files can be infected too, if you are asked to run macro’s. Click ‘no’ and close the document and let your IT department know about the breach.
