Dikkat Ransomware – Delivery Methods
Dikkat ransomware could spread its infection via different methods. The payload file that initiates the malicious script for this ransomware, which in turn infects your computer machine, is circling the Internet and a malware sample has been found by Karsten Hahn – a malware researcher. You can see the VirusTotal detections for different security programs of that sample by checking the screenshot below:
Dikkat ransomware could also distribute its payload file along social media websites and file-sharing networks. Freeware applications which are found on the Web could be presented as useful but at the same time could be hiding the malicious script for the cryptovirus. Refrain from opening files right when you have downloaded them, especially if they come from dubious sources such as links or e-mails. Instead, you should scan them beforehand with a security tool, while also checking the sizes and signatures of these files for anything that seems suspicious. You should read the ransomware prevention tips thread on the forum.
Dikkat Ransomware – More Information
Dikkat is the name of this ransomware cryptovirus. That is what is says at the top of its ransom message screen, but Dikkat is a Turkish word that means Attention. Its payload file is found inside a file called Kripto.exe so some researchers have dubbed it “Kripto”. The whole ransom note is written in the Turkish language. That suggests that Turkish-speaking users will be the main target of attacks for the ransomware, but does not exclude somebody else getting infected as well.
Dikkat ransomware might make entries in the Windows Registry aiming to achieve a higher level of persistence. Those registry entries are typically designed in a way that will start the virus automatically with each launch of the Windows Operating System.
The ransom message will show up inside a window after the encryption process is complete. The note provides the demands for payment and similar instructions. The note of Dikkat may have a lockscreen feature and is written in Turkish as already mentioned above. You can see that note from the below screenshot:
That ransom message reads the following:
!!! Dikkat !!!

A rough translation of the note in English will look like the following:
!!! Attention !!!
WARNING: ALL DATA AND FILES ON YOUR COMPUTER ARE ENCRYPTED!
WE HAVE A FEE REQUIRED OF 500TL FOR YOUR FILES YOU ENGAGED IN YOURSELF.
UNLESS YOU HAVE PAID THE SPECIFIED CHARGES YOU ARE NOT CONNECTED TO YOUR SYSTEM AND DO NOT OPEN YOUR LOCKED FILES.
YOU CAN NOT RETURN ANYONE TO YOU THROUGH YOUR FILES YOU CAN TELL AS A FUNCTIONAL EXPERIENCE.

The developer of the Dikkat cryptovirus has written a big threat message, but doesn’t reveal much. You are demanded to pay 500 in the Turkish Lira currency which equals 135 US dollars. If you get your computer infected with the malware, you should NOT under any circumstances pay the cybercriminal who is behind it. Nobody could guarantee that you will get your files restored.
Dikkat Ransomware – Encryption Process
The Dikkat ransomware is a variant of HiddenTear, associated with the HiddenTear/EDA2 open source project. Chances are that is uses AES for its encryption algorithm and has a high probability to seek and encrypt files, which have the same extensions encrypted by previous HiddenTear variants. These extensions are:
→.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp
The Dikkat cryptovirus could be set to delete the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
If that command is executed, the encryption process will become more efficient as it eliminates one of the viable ways to restore your files. Read on to check out what ways you could try to recover your data.

- Step 5
Step 1: Scan for Dikkat with SpyHunter Anti-Malware Tool
Ransomware Automatic Removal - Video Guide
Step 2: Uninstall Dikkat and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Dikkat on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Dikkat there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Dikkat
Step 5: Try to Restore Files Encrypted by Dikkat.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and Dikkat aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
