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 !!!

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.
