The malicious emails that deliver the .qwerty ransomware payload might activate emotional triggers making you more prone to download a critical attached file or visit a web page. Both ways grant the threat access to your PC. Furthermore, hackers may spoof the email sender and the email address posing as representatives of well-known companies, home or business services, websites, etc.

The conducted analyses of .qwerty file virus’ samples reveal that a single executable file named Instalador.exe is capable of triggering the attack. This file may be embedded in a document, PDF, text or another file that can be then distributed via email attachments, instant messaging services, torrent websites, and social media.

SInfection Flow of .srpx File Virus a.k.a Serpent Ransomware

The .qwerty file virus is a specific kind of malware aims to encrypt files bearers of valuable information stored on the compromised host. After encryption, the access to all encrypted files is wholly restricted and they are marked with the .qwerty file extension.

  • %Temp%
  • %Roaming%
  • %UserProfile%

The .qwerty file virus is a sophisticated threat and as a such, it can compromise various system settings like those of the Registry Editor.

Probably you already suspect what .qwerty virus achieve by modifying these two keys.

By establishing its malicious payload Infecdor.exe as to start by default on each system load the ransomware grants its persistent presence on the system. The functionalities of same subkeys can also be used in the final stage of the attack when the virus needs to display its ransom message on the PC screen.

The ransom note file contains message written in Portuguese that reads the following:

→.tx, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .odt, .png, .csv, .sql, .mdb, .php
