Foop Virus Removal Guide (+Decrypt .foop files)

Foop – General Info

Foop is a malicious software working as typical ransomware. Michael Gillespie, the well-known virus researcher, first discovered this new name in the DJVU ransomware family.

Foop was developed for the sole function to encrypt all popular file types. Realistically, as quickly as the file encryption is effectively accomplished, the users are not able to get access to them. Foop ransomware includes its own “.foop” to all the encrypted data. For example, the file “price_list.xls”, when crypted by Foop, will be titled as “price_list.xls.foop”. As soon as the encryption is achieved, Foop puts its own distinct text document (_readme.txt) into all the folders that store the encrypted files.

The message stated by _readme.txt requesting for the random os extremely similar to the notifications provided by other ransomware threats coming from the DJVU family. The warning generally shows that the information has been secured and the only service to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely real.

The approach to secure the files used by Foop is not completely investigated. However, there is no doubt that each computer owner might be released an unique decryption key, which is definitely special. It is exceptionally tough to recuperate the information without the proper type in location.

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

Don't worry, you can return all your files! virus

One more peculiarity of the Foop ransomware is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the criminals who have released the Foop virus into the world wide web. In order to get the key and bring back the essential information, the users are informed to connect with the scams by means of email or by telegram and to pay the ransom in the quantity of $980.

The message likewise states that the people should get in touch with the Foop authors within 72 hours upon the moment of the information file encryption. The alert shows that by doing so the people will obtain a 50% discount rate, for that reason, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we strongly recommend that you do not pay the ransom. There is no assurance that these online criminals will keep their pledges, so they may not care at all what the victims feel about the encryption, even when the amount of the ransom is gotten into their accounts. Hence, paying ransom typically does not lead to an effective healing. So, the users may just lose their money for absolutely nothing.

Likewise, we prompt you not to contact the frauds as they instruct. Do not transfer cash into their wallets. There are no applications that might break the Foop virus or restore the information at no cost. Therefore, the only correct decision is to bring back the data from possible backups (if readily available).
