Fatp Virus Ransomware

Fatp is a harmful software application working as common ransomware. Michael Gillespie, the widely known malware researcher, very first found this new name in the DJVU ransomware family.

Fatp was created for the sole function to encrypt all popular file types. Rationally, as soon as the encryption is effectively achieved, the users are unable to get access to them. Fatp virus adds its own “.fatp” to all the encrypted data. For instance, the file “price_list.xls”, as soon as crypted by Fatp, will be titled as “price_list.xls.fatp”. When the file encryption is achieved, Fatp puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.

The alert specified by document requesting the random os really comparable to the alerts provided by other ransomware dangers belonging to the DJVU family. The warning generally shows that the information has been encrypted and the only service to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.

The approach to secure the files used by Fatp is not entirely investigated. However, there is no doubt that each computer system owner may be released an unique decryption key, which is definitely special. It is very difficult to recuperate the information without the appropriate type in place.

“Don’t worry, you can return all your files!”, from text file message:

message from Fatp virus

One more peculiarity of the Fatp infection is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have released the Fatp infection into the web. In order to get the key and bring back the essential data, the users are told to connect with the frauds via e-mail or by telegram and to pay the ransom in the quantity of $980.

The message also says that the people should contact the Fatp authors within 72 hours upon the minute of the information encryption. The alert shows that by doing so the people will get a 50% discount, therefore, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we highly advise that you do not pay the ransom. There is no warranty that these online criminals will keep their guarantees, so they may not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Thus, paying ransom typically does not lead to a successful healing. So, the users may simply lose their money for nothing.

Likewise, we prompt you not to contact the scams as they advise. Do not move loan into their wallets. There are no applications that could break the Fatp ransomware or bring back the data for free. Therefore, the only proper choice is to restore the information from possible backups (if offered).
