Alka Virus – Details
Alka is a destructive software functioning as common ransomware. Michael Gillespie, the well-known malware researcher, first discovered this new name in the DJVU ransomware family.
Alka was developed for the sole purpose to encrypt all popular file types. Logically, as quickly as the encryption is successfully achieved, the users are not able to get access to them. Alka ransomware adds its own “.alka” to all the encrypted files. For instance, the file “price_list.xls”, once crypted by Alka, will be titled as “price_list.xls.alka”. Once the encryption is achieved, Alka puts its own special text file (_readme.txt) into all the folders that save the encrypted files.
The message stated by _readme.txt asking for the random os really similar to the alerts provided by other ransomware dangers belonging to the DJVU family. The warning generally indicates that the data has been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.
The method to encrypt the files utilized by Alka is not completely investigated. Nevertheless, there is no doubt that each computer owner may be released a special decryption key, which is absolutely special. It is exceptionally difficult to recuperate the information without the suitable type in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Alka virus 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 scoundrels who have actually launched the Alka virus into the internet. In order to obtain the key and bring back the crucial data, the users are informed to connect with the frauds via email or by telegram and to pay the ransom in the amount of $980.
The message likewise says that individuals ought to contact the Alka authors within 72 hours upon the moment of the data file encryption. The alert suggests that by doing so individuals will obtain a 50% discount rate, for that reason, the ransom quantity drops down to $490.
No matter what the quantity of the ransom is, we strongly recommend that you do not pay the ransom. There is no assurance that these online scoundrels will keep their promises, so they may not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts. Hence, paying ransom often does not lead to an effective recovery. So, the users might merely lose their money for nothing.
Likewise, we urge you not to get in touch with the frauds as they advise. Do not move money into their wallets. There are no applications that could break the Alka virus or bring back the data for free. Therefore, the only appropriate choice is to bring back the information from possible backups (if readily available).
