Known as cryptolockers, Ransomware attacks are malicious software that hold computer data hostage. These viruses encrypt your storage media by infecting your operating system so that you no longer have access to your important information. Despite the robust security procedures put in place to eradicate them, computers remain vulnerable to these malware. Find out how to recover your files after an infection by this type of spyware.
Ransomware: what is it?
Ransomware is malicious software that attacks data stored on a computer and prevents you from accessing it. It is usually sent by hackers who demand money in exchange for the decryption keys to your information.
The different types of Ransomware
There is a wide range of Ransomware software. Most of them are harmful. The various strains of these cryptolockers work in the same way and share one thing in common: targeting your data. Among these malicious programs, we can mention:
Data blockers
Also known as crypto ransomware, this malicious software is the most commonly used to attack files on a computer. It encrypts and modifies them so that they become inaccessible. They are no longer recognized by your computer and you can no longer open them.
Indeed, data blockers can attack your files when you do not perform daily backups. In order to recover your information, the hackers ask you to pay a ransom to obtain the decryption key.
Cryptolockers
Better known as computer lockers, these prevent you from accessing your computer’s interface. Cryptolocker attacks consist of blocking access to your device only, without affecting your files. They generally spread across your computer via email and encrypt your data using public-key encryption.
Once the targeting is complete, the virus displays a ransom demand message on your screen to recover your information.
Cryptoviruses
These are malicious programs that attack your data by encrypting it. The virus encrypts your documents and renders them inaccessible. It then displays a message on your screen asking you to pay a sum of money in order to recover your information.
Scarewares
This is malicious software that usually poses as an antivirus program. It appears on your screen as a pop-up to inform you that a problem has been detected on your device. Instead of extorting money from you, the virus recommends that you purchase an antivirus program in order to recover your information. If you subscribe to or purchase the antivirus, the hacker takes all your personal data.
How to recover data after Ransomware attacks?
Data recovery in the event of Ransomware attacks, as well as viruses, is a process that requires effective procedures to be put in place. In the event of an infection on your computer, to recover your information, you will need to :
