Zobm Virus Removal Guide (+Decrypt .zobm files)

Zobm – Ransomware

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

Zobm was developed for the sole function to encrypt all popular file types. Realistically, as soon as the file encryption is effectively accomplished, the users are unable to get access to them. Zobm virus adds its own “.zobm” to all the encrypted data. For instance, the file “price_list.xls”, as soon as modified by Zobm, will be entitled as “price_list.xls.zobm”. As soon as the encryption is achieved, Zobm puts its own distinct text file (_readme.txt) into all the folders that store the encrypted files.

The message mentioned by _readme.txt requesting for the random os very comparable to the notices given by other ransomware risks belonging to the DJVU family. The warning generally shows that the data has been secured and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.

The technique to encrypt the files used by Zobm is not totally researched. Nevertheless, there is no doubt that each computer system owner might be released a special decryption key, which is definitely distinct. It is exceptionally tough to recover the data without the suitable key in location.

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

message from Zobm virus

One more peculiarity of the Zobm virus is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the scoundrels who have actually released the Zobm ransomware into the internet. In order to obtain the key and bring back the important data, the users are informed to get in touch with the scams via email or by telegram and to pay the ransom in the quantity of $980.

The message also says that the people must contact the Zobm authors within 72 hours upon the minute of the information encryption. The alert indicates that by doing so individuals will obtain a 50% discount, 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 scoundrels will keep their pledges, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts. For this reason, paying ransom often does not result in an effective recovery. So, the users might merely lose their money for nothing.

Similarly, we urge you not to contact the scams as they instruct. Do not move cash into their wallets. There are no applications that could crack the Zobm ransomware or bring back the data for free. For that reason, the only appropriate decision is to restore the information from possible backups (if available).
