How to protect your business?


Avoid Email Links and Attachments

Phishing attacks are the most common way to spread ransomware. So, avoid opening email attachments or clicking on links, unless you know what it is. Even if you trust the sender be careful because his email account may have been hacked.  If you want to find out more info about phishing attacks and how to protect your business, we have a blog post about this.


Avoid Pirated software programs

Never install pirated software on your computer and always double-check the software you download. The growing number of ransomware attacks increased lately, due to the ease of downloading software programs. Cybercriminals now host websites from which ransomware programs can be downloaded easily.


Keep multiple backups

Back up regularly sensitive and important information. In case of an attack, such a step will allow you to quickly restore all your data and recover from a ransomware attack without paying a ransom to get the data back.


Software updates

Constantly, maintain up-to-date security software, operating system, and browsers on your computers.


Password management

We strongly recommend you use complex passwords for your accounts and files. In addition, please enable Multi-Factor Authentication on all platforms that support it. A password manager will greatly help, for example, KeePass and Bitwarden.


Ad blocker blockers

Use ad blockers to securely navigate on internet. Criminals have also started using compromised advertising (malvertising) to spread ransomware. These can target trusted websites. Ad blockers can protect against malvertising. For example, a good ad blocker is Privacy Badger.


Business solutions

For business use, we recommend to centrally manage PCs & Antivirus, enforce security policies and use advanced email protection.


Real-life situation

Your employee is receiving an email from a friend. This includes a link to a fun video. The employee follows the link and clicks on the following pop-ups.

Later that day, his screen starts to change colour, and a window appears informing him that all the files on his computer have been hijacked and encrypted. He will not be able to access anything if he does not pay a ransom. If he chooses not to pay, he may never have access to the files again.

It’s always better to prevent this attack than to try to recover your data after encryption.
