Held Virus Ransomware

Held is a harmful software application working as common ransomware. Michael Gillespie, the widely known virus researcher, first discovered this new name in the DJVU ransomware family.

Held was developed for the sole function to encrypt all popular file types. Logically, as quickly as the encryption is effectively accomplished, the users are not able to get access to them. Held virus includes its own “.held” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Held, will be titled as “price_list.xls.held”. As soon as the encryption is achieved, Held puts its own distinct text document (_readme.txt) into all the folders that save the encrypted files.

The alert specified by text file asking for the random os very similar to the alerts given by other ransomware threats coming from the DJVU family. The caution basically indicates that the data has been secured and the only service to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.

The method to secure the files utilized by Held is not entirely looked into. However, there is no doubt that each computer owner might be provided an unique decryption key, which is absolutely special. It is extremely hard to recover the data without the proper type in location.

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

One more peculiarity of the Held infection is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the criminals who have actually released the Held ransomware into the world wide web. In order to get the key and bring back the essential information, the users are informed to contact the frauds through e-mail or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that individuals should contact the Held authors within 72 hours upon the minute of the information file encryption. The alert indicates that by doing so individuals will acquire a 50% discount rate, for that reason, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we highly advise that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts. Thus, paying ransom frequently does not lead to a successful recovery. So, the users might simply lose their money for absolutely nothing.

There are no applications that could break the Held virus or restore the information at no charge. For that reason, the only right choice is to bring back the information from possible backups (if offered).
