What is Keversen Ransomware
Keversen is a ransomware-type virus that targets strong encryption of data. This is meant to tug victims into paying the so-called ransom in order to decrypt the blocked files. All instructions on the recovery process get revealed after your files end up encrypted. The Keversen virus renames a wide range of personal data (photos, videos, documents, databases, etc.) with the .keversen extension. To illustrate, a file like
1.pdf will change to
1.pdf.keversen straight after encryption. All of this happens in a blink of an eye, so there is no way to prevent it unless you have a special anti-ransomware program installed. Then, right after this stage of infection gets to a close, Keversen Ransomware moves next to creating the !=READMY=!.txt note, which sheds some words on how to regain your data.

At first, cybercriminals are trying to calm you down by saying your files are safe and can be restored. They are blocked from access until you pay for special decryption tools stored by the swindlers. It is also mentioned that all the compromised data has been uploaded to private servers and will be sold to the press or other parties in case you refuse to pay the ransom. To obtain the price and details on completing the payment, victims are asked to contact developers via email@example.com or firstname.lastname@example.org email addresses with their personal ID as the letter subject. Additionally, extortionists offer to send 2 or 3 non-important files to prove they can decrypt your data. Unfortunately, collaborating with malware developers might be the only way to solve the issue. They are the only figures able to grant full access back to your data. Otherwise, using third-party tools is uncertain and risky as they can damage your files. Keversen Ransomware usually spreads onto business networks that wield enough money to pay the ransom. Despite this, regular users may get under attacks from this ransomware as well. If you want to avoid choosing the ransom as a recovery option, then backup copies can save you in this scenario. Make sure to delete the virus and move the copies of blocked data to your system. Below, we will unwrap all the necessary steps for deleting the malware. It is important to do unless you want to have collaboration with swindlers.
