Uyari Ransomware – Distribution Method

Uyari ransomware might be using targeted attacks to infect users, mainly who speak Turkish, but other distribution methods are not an exclusion. It might also be distributed with various methods – it all depends what the cybercriminals decided to use as an entry point. Spam mail delivering letters with malicious attachments, exploit kits released for a software which still has a vulnerability or is not updated, social media and file-share networks – the possibilities are huge. Be very careful with what you do online and avoid suspicious emails, links, websites and the like. Do not give privileges to programs with an unknown origin.

Uyari Ransomware – A Closer Look

Uyari is the name of a ransomware, based on HiddenTear. It is named after the first word in the ransom note, which in English translates as “WARNING”. Believed to target Turkish users, because its ransom note is written in the Turkish language. This does not in any way exclude the possibility of other people to be targeted and infected by this crypto-virus. The ransom note also claims that the virus is CryptoLocker, much like the first CryptoWall ransomware did. The AVG malware researcher, Jakub Kroustek, has identified a sample as being part of HiddenTear after all.

Uyari ransomware creates the following files:



and the following registry entry, afterward:


That tactic allows it to remain persistent and start with each boot of the Windows Operating System.

Next, the Uyari ransomware places the .locked file extension on encrypted files. After that operation is done, the file DOSYALARINIZA ULAŞMAK İÇİN AÇINIZ.html is loaded and it contains the ransom message, written in Turkish. You can see a picture of it here:


The text from the ransom note reads:
