DEADBYDAWN Virus 🔐 (.OGUTDONRE Files) — How to Remove?

The Deadbydawn virus falls under the ransomware type of malicious agent. Malware of this type encrypts all the data on your PC (images, documents, excel sheets, music, videos, etc) and adds its own extension to every file, creating the README0.txt text files in each directory containing encrypted files.

What is known about the Deadbydawn virus?

☝️ A strictly accurate designation for the Deadbydawn is “a ransomware-type malicious agent”.

Deadbydawn appends its extra .OGUtdoNRE extension to every file’s title. For example, an image named “photo.jpg” will be turned into “photo.jpg.OGUtdoNRE”. Just like the Excel file with the name “table.xlsx” will be renamed to “table.xlsx.OGUtdoNRE”, and so forth.

In each folder containing the encoded files, a README0.txt file will be created. Actually, malware spawns 50 identical ransom notes, that differ by the number in the name (README0 – README50). It is a ransom money note. 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 ransomware developers. That is how they do it.

Deadbydawn Summary:

In the image below, you can see what a directory with files encrypted by the Deadbydawn looks like. Each filename has the “.OGUtdoNRE” extension added to it.

How did Deadbydawn ransomware end up on my PC?

There are plenty of possible ways of ransomware injection.

There are currently three most popular methods for evil-doers to have ransomware planted in your digital environment. These are email spam, Trojan introduction and peer-to-peer networks.

Another option for ransom hunters is a Trojan horse scheme. A Trojan is an object that gets into your machine pretending to be something legal. For example, you download an installer of some program you want or an update for some program. However, what is unpacked reveals itself a harmful agent that compromises your data. As the installation wizard can have any title and any icon, you’d better be sure that you can trust the resource of the things you’re downloading. The best thing is to use the software companies’ official websites.

As for the peer file transfer protocols like torrents 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 reasonable to scan the folder containing the downloaded files with the antivirus as soon as the downloading is finished.

How do I get rid of the Deadbydawn virus?

It is important to inform you that besides encrypting your files, the Deadbydawn virus will probably install Vidar Stealer on your PC to seize your credentials to various accounts (including cryptocurrency wallets). The mentioned spyware can derive your credentials from your browser’s auto-filling data.

Sometimes criminals would decrypt few of your files to prove that they really have the decryption tool. Since Deadbydawn virus is a relatively recent ransomware, security software engineers have not yet found a method to undo its work. However, the decoding tools are frequently updated, so the effective countermeasure may soon be available.

Of course, if the tamperers do the job of encrypting victim’s essential files, the hopeless person will probably comply with their demands. Despite that, paying to criminals gives no guarantee that you’re getting your data back. It is still risky. After obtaining the ransom, the racketeers may send a wrong decryption key to the injured party. There were reports of malefactors just vanishing after getting the ransom without even writing back.

The optimal safety measure against 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 not enough. Your most crucial thing could be that file you were working upon when it all happened. But at least it is something. It is also advisable to scan your PC for viruses with the anti-malware utility after the system is rolled back.

Deadbydawn is not the only ransomware of its kind, since there are other specimens of ransomware out there that act in the same manner. Examples of those are Miqe Virus, Mito Virus, Miza, and some others. The two major differences between them and the Deadbydawn are the ransom amount and the method of encryption. The rest is the same: documents become encoded, their extensions altered, ransom notes emerge in every directory containing encoded files.

Some fortunate people were able to decrypt the arrested files with the help of the free software provided by anti-malware specialists. Sometimes the racketeers mistakenly send the decryption key to the wronged in the ransom readme. Such an epic fail allows the injured part to restore the files. But of course, one should never rely on such a chance. Make no mistake, ransomware is a tamperers’ tool to pull the money out of their victims.
