What is Gedantar ransomware? And how does it carry out its attack?

Gedantar ransomware is a new ransomware Trojan and an updated version of the Unlock92 virus which was discovered way back in November 2016. This ransomware was discovered by Karsten Hahn, a security researcher. It most likely targets Russian-speaking users based on its ransom note written in Russian.

This file-encrypting threat aims at popular file types like documents, images, audio, video, archives, databases and other kinds of files. In its encryption process, Gedantar uses the RSA 2048 encryption algorithm and renames files using the pattern, “<filename>_<8-rand-chars>.<ext>”. After it encrypts files, Gedantar ransomware drops its ransom note which is contained in a file named “<20-rand-chars>.jpg” where crooks ask victims to send email to the address, unlckr@protonmail.com or reach out to them via the TOR network. Here’s the full context of the ransom note:

“Ваши файльi были зашифрованы с помощью алгоритма Г5А-2048 Если вы хотите их вернуть то отправьте один из зашифрованных файлов на е-mai1: unIckr@protonmail.com

Если вы не получили ответ в течение суток то скачайте с сайта л.огрго]ес.согл браузер ТОК и с его помощью зайдите на сайт http://n3r2kuzhw2h7x6j5.onion – там будет указан действующий и почтовый ящик.

Попытки самостоятельного восстановления файлов могут безвозвратно их испортить!”

Moreover, Gedantar ransomware also changes the desktop wallpaper where cybercrooks behind this threat display the same threatening message. Nonetheless, paying the ransom is not recommended as these crooks can’t be trusted.
