Remove DEMON Virus (+Decrypt .DEMON files) – BlackKingdom Ransomware

DEMON Virus – Details

The DEMON stands for a ransomware-type infection. The virus comes from the BlackKingdom ransomware family. DEMON was elaborated particularly to encrypt all major file types. Once the file is encrypted people are not able to use them. DEMON adds the “.DEMON” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by DEMON, will be renamed into “myphoto.jpg.DEMON“. As quickly as the encryption is completed, DEMON places a special text file into every folder containing the encrypted data.

The message given by DEMON text file requesting the ransom is absolutely the like the statements given by other ransomware virus representatives belonging to the BlackKingdom clan. It actually points out that the information is encrypted and that the only way to restore it is to use a an unique decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by DEMON is still not appropriately examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is absolutely distinct. It is difficult to restore the files without the key available.

Another technique of DEMON is that the victims cannot gain access to the key. The key is kept on a particular server run by the frauds connected with DEMON ransomware. To get the key and recover the important information people have to pay the ransom.

Nonetheless, irrespective of the asked for amount, people should stay away from paying the ransom. Cyber frauds are not fair, so they tend to completely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive result and people just waste their money for absolutely nothing.

We strongly encourage that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack DEMON ransomware and to recover the information data free of charge. Thus, the just best decision is to recover the lost data from the available backup.

Bear in mind that the web is now overwhelmed with threats that look similar to DEMON ransomware. Destructive programs of such kind are generally elaborated to encrypt essential information and to state the demand prior to the user to pay the ransom. The peculiarity of all such ransomware threats is that all apply a comparable algorithm to create the unique decryption key for information decryption.

Hence, as long as the ransomware is still being developed or has some hidden bugs, by hand recovering the information is merely not feasible. The only way to avoid the loss of your essential files is to regularly create backups of your important information.

Bear in mind that even if you create such backups, they should be placed into a special storage utility not connect to your main PC. You may use the USB Memory Stick or external hard disk for this purpose, or refer to the help of the cloud storage. If you save your backup files on your common system they may be encrypted together with other files, so it’s absolutely not a good storage location.

How did ransomware infect my computer?

There are a number of ways used by online frauds to distribute DEMON ransom virus. Despite the fact that it is uncertain how precisely DEMON injects your system, there are some leaks through which it may penetrate the system:

  • integration with third-party software, especially freeware;
  • spam e-mails from unidentified senders;
  • websites rendering free hosting services;
  • pirated peer-to-peer (P2P) downloads.

Often DEMON virus may exist as some genuine software, for example, in the pop-ups advising users to carry out some important software updates. This is the common trick used by online scams to persuade people into downloading and installing DEMON infection manually, by methods of their direct participation in the installation process.

In addition, the criminals may refer to different e-mail spam strategies to inject destructive codes into PC. So, they may describe to sending unsolicited spam e-mails with tricky notices promoting users to download the attachments or click on certain download links, for example, the ones motivating users to open some receipts, documents, tax reports or invoices.

Needless to mention, opening such files or clicking on such dangerous links may significantly harm the system. Fictitious Adobe Flash Player upgrade alerts may result in DEMON ransom injection. As for the cracked software, these illegally downloaded programs may also contain harmful codes resulting in DEMON secret installation. Finally, injection of DEMON may take place by methods of Trojans that privately get injected into the system and install harmful tools without the user’s approval.

To start with, be really cautious when you browse the web and particularly while downloading totally free apps. Stay away from opening suspicious email attachments, especially when the sender of the email is not familiar to you.
