Qlkm Virus – Details
Qlkm is a destructive software application working as common ransomware. Michael Gillespie, the well-known malware researcher, first discovered this new name in the DJVU ransomware family.
Qlkm was developed for the sole function to encrypt all popular file types. Realistically, as quickly as the encryption is effectively accomplished, the users are not able to get access to them. Qlkm virus adds its own “.qlkm” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Qlkm, will be titled as “price_list.xls.qlkm”. When the encryption is achieved, Qlkm puts its own unique text file (_readme.txt) into all the folders that save the encrypted files.
The message stated by _readme.txt requesting for the random os extremely similar to the notices given by other ransomware threats coming from the DJVU family. The caution essentially indicates that the information has been secured and the only option to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely real.
The technique to secure the files used by Qlkm is not totally looked into. However, there is no doubt that each computer system owner might be released a special decryption key, which is absolutely distinct. It is extremely hard to recover the information without the suitable type in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Qlkm ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have released the Qlkm infection into the web. In order to acquire the key and bring back the essential information, the users are told to contact the scams through email or by telegram and to pay the ransom in the amount of $980.
The message likewise states that individuals need to get in touch with the Qlkm authors within 72 hours upon the minute of the information file encryption. The alert shows that by doing so the people will acquire a 50% discount, for that reason, the ransom amount drops down to $490.
No matter what the amount of the ransom is, we strongly advise that you do not pay the ransom. There is no guarantee that these online criminals will keep their promises, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. Thus, paying ransom typically does not result in an effective healing. So, the users might merely lose their money for absolutely nothing.

There are no applications that might split the Qlkm ransomware or restore the information at no charge. Therefore, the only appropriate decision is to restore the data from possible backups (if available).
