Robm Virus Ransomware

Robm is a destructive software application working as typical ransomware. Michael Gillespie, the widely known 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. Realistically, as quickly as the encryption is successfully achieved, the users are not able to get access to them. Robm ransomware adds its own “.robm” to all the encrypted files. For example, the file “price_list.xls”, when crypted by Robm, will be titled as “price_list.xls.robm”. When the encryption is achieved, Robm puts its own special text file (_readme.txt) into all the folders that keep the encrypted files.

The message stated by text file requesting for the random os really comparable to the notices given by other ransomware dangers belonging to the DJVU family. The warning basically indicates that the information 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 technique to secure the files used by Robm is not completely investigated. However, there is no doubt that each computer system owner may be released a special decryption key, which is definitely special. It is incredibly tough to recover the data without the proper key in place.

“Don’t worry, you can return all your files!”, from _readme.txt 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 crooks who have actually released the Robm infection into the world wide web. In order to get the key and bring back the important 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 likewise says that the people should contact the Robm authors within 72 hours upon the minute of the data encryption. The alert suggests that by doing so the people will obtain a 50% discount rate, for that reason, the ransom amount drops down to $490.

No matter what the amount of the ransom is, we strongly encourage that you do not pay the ransom. There is no assurance that these online crooks will keep their guarantees, so they may not care at all what the victims feel about the encryption, even when the quantity of the ransom is gotten into their accounts. Thus, paying ransom frequently does not lead to a successful healing. So, the users might merely lose their money for nothing.

Similarly, we urge you not to call the scams as they instruct. Do not move loan into their wallets. There are no applications that could split the Robm ransomware or bring back the data at no cost. Therefore, the only appropriate decision is to bring back the information from possible backups (if readily available).
