Sglh – General Info
Sglh is a harmful software working as typical ransomware. Michael Gillespie, the widely known malware researcher, very first discovered this new name in the DJVU ransomware family.
Sglh was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the encryption is effectively accomplished, the users are unable to get access to them. Sglh virus includes its own “.sglh” to all the encrypted files. For instance, the file “price_list.xls”, once crypted by Sglh, will be titled as “price_list.xls.sglh”. When the file encryption is achieved, Sglh puts its own special text document (_readme.txt) into all the folders that save the encrypted files.
The alert stated by _readme.txt requesting for the random os extremely comparable to the notices given by other ransomware threats belonging to the DJVU family. The warning basically indicates that the data has been secured and the only option to get access to it is to use a special standalone key. Regretfully, this statement is absolutely true.
The technique to secure the files utilized by Sglh is not totally researched. However, there is no doubt that each computer system owner may be issued a special decryption key, which is absolutely special. It is exceptionally hard to recover the data without the suitable type in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Sglh 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 total control by the scoundrels who have actually introduced the Sglh virus into the world wide web. In order to get the key and restore the essential data, the users are told to get in touch with the scams through e-mail or by telegram and to pay the ransom in the amount of $980.
The message also says that the people must contact the Sglh authors within 72 hours upon the moment of the data encryption. The alert suggests that by doing so the people will acquire a 50% discount, for that reason, the ransom quantity falls to $490.
No matter what the quantity of the ransom is, we highly advise that you do not pay the ransom. There is no assurance that these online scoundrels will keep their pledges, 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 result in a successful recovery. So, the users may just lose their money for absolutely nothing.
Likewise, we advise you not to get in touch with the scams as they instruct. Do not move cash into their wallets. There are no applications that could split the Sglh ransomware or bring back the data at no charge. Therefore, the only proper decision is to bring back the data from possible backups (if offered).
