Ransomware is a type of malicious software that encrypts a victim’s files. The attackers then demand a ransom from the victim to restore access to the files, hence the name.
Ransomware attacks are typically carried out using a Trojan disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment. Once activated, the ransomware can lock the user out of their computer or device or encrypt certain files on the system, making them inaccessible.
Ransomware attacks can be financially devastating and disruptive to individuals and organizations, resulting in the loss of valuable data and the inability to access important systems and files.
To protect against ransomware attacks, it is important to use strong, unique passwords and to avoid opening email attachments or clicking links from unknown sources. It is also a good idea to regularly back up important files so that they can be restored if they are lost or encrypted in a ransomware attack.
