Robm Virus Removal Guide (+Decrypt .robm files)

Robm – Ransomware

Robm is a harmful software functioning as common ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.

Robm was created for the sole purpose to encrypt all popular file types. Rationally, as soon as the encryption is successfully accomplished, the users are unable to get access to them. Robm ransomware includes its own “.robm” to all the encrypted data. For instance, the file “price_list.xls”, when crypted by Robm, will be titled as “price_list.xls.robm”. As soon as the encryption is achieved, Robm puts its own special text document (_readme.txt) into all the folders that save the encrypted files.

The message stated by document asking for the random os really comparable to the notifications given by other ransomware hazards coming from the DJVU family. The caution basically indicates that the data has been encrypted and the only option to get access to it is to use a special standalone key. Regretfully, this statement is definitely true.

The approach to encrypt the files utilized by Robm is not totally looked into. However, there is no doubt that each computer owner might be provided a special decryption key, which is definitely unique. It is incredibly tough to recuperate the information without the suitable key in location.

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

message from Robm virus

One more peculiarity of the Robm ransomware is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have introduced the Robm infection into the internet. In order to acquire the key and bring back the essential information, 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.

The message also says that individuals need to get in touch with the Robm authors within 72 hours upon the moment of the data encryption. The alert indicates 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 highly recommend that you do not pay the ransom. There is no assurance that these online criminals will keep their promises, 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. For this reason, paying ransom typically does not lead to an effective recovery. So, the users may just lose their money for absolutely nothing.

Similarly, we advise you not to call the scams as they advise. Do not move cash into their wallets. There are no applications that could crack the Robm virus or bring back the information at no cost. Therefore, the only correct choice is to restore the information from possible backups (if available).
