Sqpc Virus Ransomware

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

Sqpc was created for the sole purpose to encrypt all popular file types. Rationally, as quickly as the encryption is successfully accomplished, the users are unable to get access to them. Sqpc virus includes its own “.sqpc” to all the encrypted files. For instance, the file “price_list.xls”, when crypted by Sqpc, will be titled as “price_list.xls.sqpc”. Once the encryption is achieved, Sqpc puts its own distinct text document (_readme.txt) into all the folders that keep the encrypted files.

The alert stated by text file requesting for the random os really similar to the notifications given by other ransomware threats coming from the DJVU family. The warning generally shows that the information has been secured and the only service to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely true.

The method to encrypt the files utilized by Sqpc is not entirely looked into. However, there is no doubt that each computer system owner may be provided an unique decryption key, which is definitely distinct. It is exceptionally hard to recuperate the data without the appropriate type in place.

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

One more peculiarity of the Sqpc 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 released the Sqpc infection into the internet. In order to acquire the key and restore the crucial information, the users are informed to contact the frauds via email or by telegram and to pay the ransom in the amount of $980.

The message also states that individuals need to get in touch with the Sqpc authors within 72 hours upon the minute of the data encryption. The alert indicates that by doing so individuals will obtain a 50% discount, therefore, the ransom amount 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 warranty that these online crooks will keep their pledges, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. Hence, paying ransom typically does not lead to an effective recovery. So, the users may just lose their money for nothing.

Similarly, we urge you not to contact the frauds as they advise. Do not transfer cash into their wallets. There are no applications that might break the Sqpc virus or restore the information at no cost. Therefore, the only proper choice is to restore the data from possible backups (if available).
