Tcbu Virus Removal Guide (+Decrypt .tcbu files)

Tcbu – Ransomware

Tcbu is a malicious software functioning as common ransomware. Michael Gillespie, the well-known malware researcher, first discovered this new name in the DJVU ransomware family.

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

The alert mentioned by _readme.txt asking for the random os really comparable to the notifications offered by other ransomware threats coming from the DJVU family. The caution generally indicates that the files have been encrypted and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is definitely true.

The technique to encrypt the files utilized by Tcbu is not totally investigated. Nevertheless, there is no doubt that each computer system owner might be issued an unique decryption key, which is absolutely unique. It is extremely tough to recuperate the information without the suitable type in place.

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

One more peculiarity of the Tcbu virus 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 launched the Tcbu virus into the internet. In order to obtain the key and restore the essential data, the users are informed to get in touch with the frauds by means of e-mail or by telegram and to pay the ransom in the quantity of $980.
