What is ransomware and how can you protect yourself against its consequences?
Ransomware: a quick definition
Ransomware is malware that blocks access to a device and the files it contains by means of 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 private 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 e-mail attachment or link.
-
While browsing a compromised site.
-
After a computer intrusion into a system.
How to protect yourself against ransomware: 5 best practices

-

-
Update your tools (word processors, browsers, anti-virus software) when required.

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 intrusion attempts or abnormal behavior. It blocks threats before they manifest themselves.
On the other, it performs backups on an external medium (protected local server, secure cloud, etc.) at regular intervals. Backups can be made of the entire system or just a few critical files. In the event of an intrusion, you retain access to a copy of your encrypted files.
Some software even has the ability to block attacks and automatically restore uncompromised backups. In this way, the threat from hackers no longer carries any weight.
Ransomware: should you pay the ransom?
In the event of an attack, you may be tempted to pay the ransom. This is because the data encrypted by cybercriminals is generally worth far more than the amount demanded. However, you should be aware that there's no guarantee 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 business, and one that 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 backups to avoid contamination, and isolate the media if necessary.
-
Start a full system scan using your anti-ransomware software.
-
IF the attack is confirmed, identify the type of ransomware and use (if possible) a suitable decryption tool.
-
Restore a clean backup once the system has been cleaned.
Anti-ransomware software: choose the best!
Protection against ransomware attacks has become an obligation for companies concerned 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.
