DATAH Ransomware ([email protected])

The Datah virus belongs to the Makop ransomware family. Malware of this type encrypts all user’s data on the PC (images, documents, excel sheets, music, videos, etc) and adds its extra extension to every file, creating the +README-WARNING+.txt files in every folder with the encrypted files.

It is better to prevent, than repair and repent!

What is Datah virus?

☝️ Datah is a Makop family ransomware infection.

The renaming will be executed according to this pattern: .datah. As a part of encryption, a file named, for instance, “report.docx” will be renamed to “report.docx.[2AF20FA3].[[email protected]].datah”.

In each folder with the encoded files, a +README-WARNING+.txt file will appear. It is a ransom money memo. Therein you can find information on the ways of paying the ransom and some other information. The ransom note usually contains a description of how to buy the decryption tool from the racketeers. You can get this decryptor after contacting [email protected] by email. That is how they do it.

How did my machine catch Datah ransomware?

There are many possible ways of ransomware injection.

There are currently three most popular methods for hackers to have the Datah virus settled in your digital environment. These are email spam, Trojan injection and peer-to-peer networks.

• If you open your mailbox and see letters that look like familiar notifications from utility services providers, postal agencies like FedEx, Internet providers, and whatnot, but whose “from” field is strange to you, beware of opening those letters. They are most likely to have a ransomware item enclosed in them. So it is even more dangerous to download any attachments that come with emails like these.
• Another option for ransom hunters is a Trojan virus model. A Trojan is an object that infiltrates into your machine pretending to be something different. For example, you download an installer for some program you need or an update for some service. However, what is unpacked reveals itself a harmful program that corrupts your data. Since the installation wizard can have any name and any icon, you’d better be sure that you can trust the source of the files you’re downloading. The best way is to use the software developers’ official websites.
• As for the peer-to-peer file transfer protocols like torrents or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never guess what you download until you get it. Our suggestion is that you use trustworthy resources. Also, it is a good idea to scan the folder containing the downloaded items with the antivirus as soon as the downloading is finished.

How do I get rid of ransomware?

It is crucial to note that besides encrypting your files, the Datah virus will most likely deploy Vidar Stealer on your machine to get access to credentials to different accounts (including cryptocurrency wallets). That spyware can derive your credentials from your browser’s auto-filling cardfile.

Sometimes criminals would decode few of your files so you know that they indeed have the decryption program. Since Datah virus is a relatively recent ransomware, safety measures developers have not yet found a method to undo its work. Nevertheless, the decoding tools are constantly upgraded, so the solution may soon be available.

Of course, if the evildoers succeed in encoding victim’s essential data, the desperate person will most likely fulfill their demands. However, paying to criminals does not necessarily mean that you’re getting your blocked information back. It is still risky. After obtaining the money, the racketeers may send a wrong decryption code to the victim. There were reports of criminals just disappearing 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 storage or at least on an external drive. Of course, that might be insufficient. The most crucial thing could be that one you were working upon when it all happened. Nevertheless, it is something. It is also advisable to scan your PC for viruses with the antivirus program after the OS is rolled back.

Datah is not the only ransomware of its kind, since there are other specimens of ransomware out there that act in the same manner. For instance, Unkno, Kaaa, Uajs, and some others. The two major differences between them and the Datah are the ransom amount and the method of encryption. The rest is the same: files become inaccessible, their extensions altered, ransom notes are created in each directory containing encrypted files.

Some fortunate people were able to decrypt the blocked files with the aid of the free tools provided by anti-ransomware developers. Sometimes the racketeers mistakenly send the decryption code to the wronged in the ransom readme. Such an extraordinary fail allows the user to restore the files. But naturally, one should never expect such a chance. Make no mistake, ransomware is a bandits’ technology to pull the money out of their victims.

How сan I avoid ransomware infiltration?

Datah ransomware has no endless power, neither does any similar malware.

You can defend your computer from ransomware attack within several easy steps:

• Ignore any emails from unknown mailboxes with unknown addresses, or with content that has nothing to do with something you are waiting for (can you win in a lottery without participating in it?). In case the email subject is likely something you are waiting for, scrutinize all elements of the dubious email carefully. A hoax email will surely have mistakes.
• Avoid using cracked or unknown software. Trojans are often shared as a part of cracked products, most likely under the guise of “patch” which prevents the license check. But dubious programs are difficult to distinguish from reliable software, as trojans sometimes have the functionality you seek. Try to find information on this program on the anti-malware message boards, but the optimal way is not to use such software.
• And to be sure about the safety of the objects you downloaded, scan them with GridinSoft Anti-Malware. This program will be a powerful shield for your personal computer.

FAQ

🤔 Are the “.datah” files accessible?

There’s no way to do it, unless the files “.datah” files are decrypted.

🤔 The encrypted files are very important to me. How can I decrypt them quickly?

Hopefully, you have made a copy of those important files. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. All other solutions require time.

🤔 If GridinSoft deletes the Datah malware, will it also delete my files that were encrypted?

Of course not. The encrypted files are not harmful, so they won’t be deleted.

GridinSoft Anti-Malware will delete the viruses from your PC. The ransomware that has infected your PC is most likely still functional and running scans periodically to arrest any new files you might create on your PC after the attack. As it has been mentioned above, the Datah malware does not come alone. It installs backdoors and keyloggers that can take your account passwords by trespass and provide criminals with easy access to your system in the future.

🤔 What actions should I take if the Datah malware has blocked my computer and I can’t get the activation key.

In such an unfortunate situation, you need to have a flash memory drive with a previously installed Trojan Killer. Use Safe Mode to perform the procedure. You see, the ransomware starts automatically as the system launches and encodes any new files created or brought into your system. To block this function – use Safe Mode, which allows only the essential applications to run upon system start. Consider reading our manual on running Windows in Safe Mode.

🤔 And what should I do now?

Many of the encoded files might still be at your disposal

• If you sent or received your critical files through email, you could still download them from your online mailbox.
• You might have shared images or videos with your friends or family members. Simply ask them to post those images back to you.
• If you have initially got 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 as well.
• Maybe you still have the needed files on your old computer, a notebook, cellphone, flash memory, etc.

HINT: You can use file recovery utilities² to retrieve your lost information since ransomware blocks the copies of your files, removing the original ones. In the tutorial below, you can learn how to use PhotoRec for such a recovery, but remember: you won’t be able to do it before you kill the ransomware itself with an antivirus program.
