What is ransomware and how can you protect yourself against its consequences?
Ransomware: a quick definition
Ransomware is malicious software that blocks access to a device and the files it contains using an encryption system. The aim is to force the victim to pay a ransom in order to regain access. While this can be a dangerous problem for individuals, the risk is even greater for businesses, which often store sensitive data (banking information, customer data, etc.).
Devices can be infected in a number of ways:
-
Following the opening of a malicious attachment or link received by email.
-
While browsing a compromised site.
-
After a computer intrusion into a system.

Anti-ransomware FAQs
How does anti-ransomware software work?
Anti-ransomware software protects your company's data and files on two fronts: cybersecurity and system backup.
On the one hand, anti-ransomware software alerts you to attempted intrusions or abnormal behaviour. It blocks threats before they manifest themselves.
On the other, it makes back-ups on an external medium (protected local server, secure cloud, etc.) at regular intervals. The back-ups may concern the entire system or just a few critical files. In the event of an intrusion, you will still have access to a copy of your encrypted files.
Some software even has the ability to block attacks and automatically restore uncompromised backups. So the threat from hackers is no longer a threat.
Ransomware: should you pay the ransom?
In the event of an attack, you may be tempted to pay the ransom. Generally speaking, the data encrypted by the cybercriminals is worth much more than the sums demanded. However, you should be aware that there is no proof that the hackers will stop there. If you've paid once, you'll probably pay a second time, or even a third. It's a risky way to go, and one that also gives criminals more means to develop their malicious activities.
How do I know if I'm exposed to ransomware?
Ransomware spreads across an entire system over a period of several days, sometimes as little as 24 hours. If you think you've been attacked, you need to react quickly. Here are the steps to follow:
-
Immediately disconnect the workstation from the network to prevent it spreading to other machines.
-
Stop automatic back-ups to avoid contamination and isolate the media if necessary.
-
Run a full system scan using your anti-ransomware software.
-
If the attack is confirmed, identify the type of ransomware so that you can use an appropriate decryption tool (if possible).
-
Restore a clean backup once the system has been cleaned.
Anti-ransomware software: opt for the best!
Protection against ransomware attacks has become an obligation for businesses that care about their data. To protect your systems from the many threats, choose the anti-ransomware protection solution from our list best suited to your specific needs.
