Ransomware attacks are one of the main threats on the web. Here's what they are and the main strategies to implement to defend yourself.
Un ransomware is a type of computer virus that takes control of a user's computer by encrypting data and making it impossible to access networks, systems, and functionality.
Ransomware attacks have been a phenomenon that has increased sharply in recent years. According to iran phone number list a Sophos research, in 2020, approximately one in three Italian companies suffered a ransomware attack that bypassed their defenses.
Ransomware attacks are therefore more frequent than one might imagine.
Let's find out together how ransomware attacks work and how to protect yourself.

What is ransomware and how does it work?
Ransomware is an emerging type of malware that takes control of a victim's computer, preventing access to systems and files , and then demands a ransom payment to recover the files and restore normal operation.
Ransomware is usually spread through phishing or clickjacking attacks . The user is tricked into clicking on an external link to install infected files, usually with an .exe extension, on their computer.
Once inside the network, the virus is able to spread to all devices, preventing users from accessing data or blocking the devices themselves.
Once cybercriminals have possession of the files, there is no software or security system that can return them to the owner. Paying the ransom is not a solution, however, because, in addition to having legal consequences, attackers often do not return the files even after payment. It is therefore necessary to invest in backup and disaster recovery solutions in advance to keep your data safe and ensure operational continuity.
