HORON Virus Removal Guide (+Decode .horon files) – Djvu Ransomware

HORON Virus – Details

The HORON mean a ransomware-type infection. The infection comes from the Djvu ransomware family. HORON was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are not able to use them. HORON adds the “.horon” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by HORON, will be renamed into “myphoto.jpg.horon“. As soon as the encryption is completed, HORON places a special text file into every folder containing the encrypted data.

The message given by HORON text file requesting the ransom is definitely the like the statements given by other ransomware virus representatives coming from the Djvu clan. It actually discusses that the information is encrypted which the only way to restore it is to use a a special decryption key. Regretfully, this is definitely true. The sort of cryptography mechanism used by HORON is still not properly examined. Still, it is definitely specific that each victim may be given the specific decryption key, which is totally distinct. It is difficult to restore the files without the key available.

Another technique of HORON is that the victims cannot get to the key. The key is saved on a particular server run by the frauds associated with HORON ransomware. To get the key and recover the important information people need to pay the ransom, which totals up to $980. To obtain the payment details users are advised to contact the frauds through email or telegram. The alert also shows that the users require to contact the HORON developers within 72 hours after the encryption happened. The message says that doing so users will get a 50% discount, so the ransom amount will drop down to $490.
