DOEBNANK Virus 🔐 (.CRYPTED_DOEBNANK Files) — How to Remove?

The Doebnank virus belongs with the ransomware type of infection. A harmful program of such sort encrypts all user’s data on the PC (photos, documents, excel sheets, music, videos, etc) and adds its specific extension to every file, creating the how_to_back_files.html text files in each folder with the encrypted files.

What is Doebnank virus?

☝ A strictly accurate description for the Doebnank is “a ransomware infection”.

Doebnank adds its specific .crypted_doebnank@outhyred_com extension to the title of each encoded file. For instance, a file entitled “photo.jpg” will be renamed to “photo.jpg.crypted_doebnank@outhyred_com”. Just like the Excel sheet named “table.xlsx” will be changed to “table.xlsx.crypted_doebnank@outhyred_com”, and so forth.

In every folder containing the encoded files, a how_to_back_files.html text document will be found. It is a ransom money memo. It contains information about the ways of contacting the racketeers and some other information. The ransom note usually contains a description of how to buy the decryption tool from the Doebnank developers. You can obtain this decrypting software after contacting crypted_doebnank@outhyred_com through email. That is it.

How did my computer get infected with Doebnank ransomware?

There are many possible ways of ransomware infiltration.

Nowadays, there are three most exploited methods for tamperers to have ransomware acting in your digital environment. These are email spam, Trojan injection and peer-to-peer networks.

If you access your mailbox and see emails that look just like notifications from utility services companies, delivery agencies like FedEx, Internet providers, and whatnot, but whose sender is unknown to you, be wary of opening those letters. They are most likely to have a harmful file enclosed in them. Therefore, it is even more dangerous to open any attachments that come with letters like these.

As for the peer-to-peer networks like torrent trackers or eMule, the threat is that they are even more trust-based than the rest of the Web. You can never know what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is a good idea to scan the directory containing the downloaded files with the antivirus as soon as the downloading is done.

How to remove the Doebnank virus?

It is crucial to note that besides encrypting your files, the Doebnank virus will most likely install the Azorult Spyware on your PC to get access to credentials to different accounts (including cryptocurrency wallets). That spyware2 can extract your credentials from your browser’s auto-filling cardfile.

Often tamperers would decrypt few of your files so you know that they really have the decryption program. As Doebnank virus is a relatively recent ransomware, security software designers have not yet found a way to reverse its work. However, the anti-ransomware instruments are frequently updated, so the effective countermeasure may soon be available.

Understandably, if the malefactors succeed in encoding someone’s essential files, the hopeless person will most likely fulfill their demands. Despite that, paying to racketeers does not necessarily mean that you’re getting your files back. It is still dangerous. After obtaining the ransom, the racketeers may send a wrong decryption key to the injured party. There were reports about hackers simply vanishing after getting the money without even bothering to reply.

The optimal countermeasure to ransomware is to have a system restore point or the copies of your critical files in the cloud disk or at least on an external disk. Obviously, that might be insufficient. Your most crucial thing could be that file you were working on when it all started. Nevertheless, it is something. It is also advisable to scan your drives with the anti-malware utility after the OS is rolled back.

There are other ransomware products, besides Doebnank, that work similarly. For instance, Iotr, Hhoo, Hhee, and some others. The two major differences between them and the Doebnank are the ransom amount and the method of encryption. The rest is the same: files become encrypted, their extensions changed, ransom notes are found in each directory containing encrypted files.

Some fortunate people were able to decrypt the arrested files with the aid of the free tools provided by anti-ransomware specialists. Sometimes the criminals mistakenly send the decryption code to the wronged in the ransom readme. Such an epic fail allows the injured part to restore the files. But obviously, one should never rely on such a chance. Remember, ransomware is a criminals’ technology to pull the money out of their victims.

How to avert ransomware infection?

Doebnank ransomware doesn’t have a endless power, so as any similar malware.

You can armour your PC from ransomware attack within three easy steps:

  • Never open any letters from unknown mailers with unknown addresses, or with content that has likely no connection to something you are waiting for (how can you win in a lottery without even taking part in it?). In case the email subject is more or less something you are expecting, scrutinize all elements of the dubious email carefully. A fake email will surely have a mistake.
  • Never use cracked or unknown programs. Trojan viruses are often distributed as an element of cracked products, most likely as a “patch” which prevents the license check. But potentially dangerous programs are difficult to distinguish from trustworthy ones, as trojans sometimes have the functionality you need. You can try searching for information on this software product on the anti-malware message boards, but the best way is not to use such software.

Many of the encoded files might still be at your disposal

  • If you exchanged your critical files by email, you could still download them from your online mailbox.
  • You may have shared images or videos with your friends or relatives. Just ask them to send those images back to you.
  • If you have initially downloaded any of your files from the Internet, you can try downloading them again.
  • Your messengers, social media pages, and cloud drives might have all those files too.
  • It might be that you still have the needed files on your old computer, a notebook, phone, flash memory, etc.

HINT: You can employ file recovery programs5 to retrieve your lost information since ransomware encrypts the copies of your files, deleting the original ones. In the tutorial below, you can see how to use PhotoRec for such a recovery, but be advised: you can do it only after you kill the ransomware itself with an anti-malware program.

Also, you can contact the following governmental fraud and scam sites to report this attack:

To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.
