Guesswho Virus Removal Guide (+Decode .guesswho files) – Rapid Ransomware

Guesswho Virus Ransomware

The Guesswho stands for a ransomware-type infection. The infection comes from the Rapid ransomware family. Guesswho was elaborated specifically to encrypt all major file types. When the file is encrypted people are unable to use them. Guesswho adds the “.guesswho” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Guesswho, will be renamed into “myphoto.jpg.guesswho“. As quickly as the encryption is finished, Guesswho places a special text file into every folder containing the encrypted data.

The message given by Guesswho text file asking for the ransom is absolutely the like the statements given by other ransomware virus representatives belonging to the Rapid clan. It literally points out that the info is encrypted which the only way to bring back it is to use a a special decryption key. Sadly, this is absolutely true. The sort of cryptography mechanism applied by Guesswho is still not properly examined. Still, it is absolutely certain that each victim may be given the specific decryption key, which is completely distinct. It is impossible to bring back the files without the key available.

Another trick of Guesswho is that the victims cannot gain access to the key. The key is kept on a specific server run by the frauds associated with Guesswho ransomware. To get the key and recover the important info people need to pay the ransom, which totals up to $3000. To acquire the payment information users are advised to contact the frauds through email or telegram. The alert also indicates that the users require to contact the Guesswho developers within 72 hours after the files encryption took place. The message says that doing so users will get a 50% discount, so the ransom quantity will drop down to $1500.

Nonetheless, irrespective of the asked for quantity, people should stay away from paying the ransom. Cyber frauds are not fair, so they tend to totally ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom normally does not give any positive result and people simply lose their money for absolutely nothing.

We strongly advise that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Guesswho ransomware and to recover the information data free of charge. Hence, the only right decision is to recover the lost data from the available backup.
