Derp Virus Removal Guide (+Decrypt .derp files)

Derp Virus Ransomware

Derp is a malicious software functioning as common ransomware. Michael Gillespie, the popular malware researcher, very first found this new name in the DJVU ransomware family.

Derp was created for the sole function to encrypt all popular file types. Logically, as soon as the file encryption is effectively accomplished, the users are unable to get access to them. Derp ransomware adds its own “.derp” to all the encrypted data. For instance, the file “price_list.xls”, as soon as modified by Derp, will be entitled as “price_list.xls.derp”. As soon as the file encryption is accomplished, Derp puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.

The message mentioned by _readme.txt requesting the random os really similar to the notifications given by other ransomware risks belonging to the DJVU family. The caution basically shows that the data has been secured and the only option to get access to it is to use an unique standalone key. Regretfully, this statement is definitely true.

The technique to encrypt the files utilized by Derp is not totally investigated. However, there is no doubt that each computer owner might be issued an unique decryption key, which is absolutely unique. It is incredibly hard to recover the information without the proper type in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

One more peculiarity of the Derp ransomware 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 scoundrels who have released the Derp infection into the web. In order to acquire the key and restore the crucial information, the users are told to get in touch with the frauds via e-mail or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that the people should call the Derp authors within 72 hours upon the moment of the information file 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 amount of the ransom is, we strongly encourage that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their guarantees, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. Thus, paying ransom typically does not lead to an effective recovery. So, the users might merely lose their money for nothing.

Similarly, we advise you not to call the frauds as they advise. Do not move money into their wallets. There are no applications that could crack the Derp ransomware or restore the information for free. Therefore, the only right choice is to bring back the information from possible backups (if available).
