Qnty ransomware is another crypto-virus that was designed to specifically lock the majority of computer files and deny user’s access to it. This virus will apply a complex algorithm technique to ensure that files remain unusable and convince computer users to obtain the decryption software in order to restore the entire .qnty files back to their original format. Due to the applied advanced technique of encryption, it would be impossible to recover the files without the proper decryption tool. This is why attackers are taking advantage of this situation to extort money from their victims.
How Qnty virus infects the computer?
There are many ways for malware authors to introduce Qnty ransomware and because of the global connection via the internet, they can easily accomplish this task. Web injectors, malicious file installers, social engineering attacks, spam email campaign, Trojan Downloader, and exploiting the RDP (remote desktop protocols) are just some of the ways and means for widespread of Qnty ransomware.
With the mentioned channels of deployment, it was observed that the majority of ransomware victims have obtained the virus via phishing email campaign. Qnty ransomware is normally embedded as an attachment to legitimate email and purporting as a valid document file. Once opened or viewed, Qnty ransomware starts the first phase of its attack. Malicious software installer comes as second widely used method to deploy Qnty ransomware. This executable file instantly launches the infection during the setup procedure and computer users will never experience any signs of the infiltration.
Attackers have two ways to deliver the goods. It is either directly load Qnty ransomware or inject a Trojan dropper on the computer that will later leverage to a ransomware infection. The latter found to be a better option because this petty virus can conceal itself better once inside the computer. Therefore, it can perform various malicious actions without being detected by security applications.
Qnty ransomware file encryption
Upon the successful penetration of the virus, it makes a connection to remote command-and-control server to fetch addition malware. The server was made also to deliver the public key to the infected computer and once obtained, Qnty ransomware will start the encryption process. The virus applies the key during the complex encryption method. In addition, all encrypted data will get appended with .qnty file extension.
Like in the mainstream of ransomware attack as Iips, Ccps, Cuag, and many more, Qnty ransomware is going to inform computer users through a generated ransom note. It contains brief description as well as method to recover the encrypted files. As usual, the victims have to pay the ransom demand before they can acquire the decryption software.
| Threat Name | Qnty Ransomware, STOP/DJVU |
|---|---|
| Threat Type | Crypto-virus, File Locker, Encryption Virus |
| File Extension | .qnty |
| Ransomware Note File | _readme.txt |
| Attacker’s email | support@sysmail.ch helprestoremanager@airmail.cc |
Backup your files
One important step before proceeding with the procedures below is to backup your files. Ransomware are not the same. Each has its unique sets of payloads aside from encrypting the files with complex method. Others tend to delete the infected files after certain period, while others keep them concealed on hidden places. In addition, ransomware decryption tools are not guaranteed to be perfect, there are instances that files suffer from damages during the decryption process.
So, create a backup copy of your entire Qnty encrypted files right now.
