How to remove Qual ransomware

Qual ransomware is file-encrypting malware from the Djvu/STOP ransomware family. The .qual extension added to encrypted file names can identify the ransomware. Unfortunately, the ransomware will encrypt all personal files and request a payment to recover them. At the moment, only users who have backups can recover files for free.

 

 

Qual ransomware belongs to the Djvu malware family. The malicious actors operating these infections release new versions regularly, with hundreds of versions already released. The versions are seemingly identical but can be identified by the extensions they add to encrypted files. This particular malware adds .qual. For example, an encrypted 1.txt file would become 1.txt.qual.

The ransomware will encrypt all personal files, including photos, pictures, videos, documents, etc. You will not be able to open any of the files that have this extension unless you first use a decryptor. However, acquiring the decryptor is not easy.

When the ransomware is done encrypting files it will drop a _readme.txt ransom note in all folders that have encrypted files. The note is the same one dropped by all other Djvu/STOP versions. It contains instructions on how to acquire a decryptor, and it involves paying $999 in ransom. The note mentions a 50% discount for users who make contact within the first 72 hours but whether that is valid is uncertain. The malware operators also offer to decrypt one file for free as long as it does not contain important information.

Here is the full _readme.txt ransom note:

If you have no backup, paying the ransom may seem like a good option but we must caution you to not engage with the cybercriminals. Even if you pay, there are no guarantees that a decryptor will be sent to you. You are dealing with cyber criminals, and there is nothing to force them to send you the decryptor. Unfortunately, many victims have not received decryptors in the past. Furthermore, ransomware will continue to thrive as long as victims pay the ransom. The money victims pay also goes towards future criminal activities.

If you have a backup, you can start recovering your files as soon as you remove Qual ransomware from your computer. We strongly recommend using an anti-malware program to delete Qual ransomware because it’s a complex infection. Once the anti-malware program no longer detects Qual ransomware, you can safely connect to your backup.

If a backup is not available, your only option is to wait for a free Qual ransomware decryptor to be released. It’s not guaranteed that it will be released but it’s still a good idea to back up encrypted files and occasionally check for a free Qual ransomware decryptor. NoMoreRansom is a good source for decryptors. If you cannot find it on NoMoreRansom, it’s unlikely to be available anywhere else.

How is ransomware distributed?

Malware is often distributed through emails. Malicious actors try to make their malicious emails resemble ones sent by legitimate companies to their customers. For example, malicious emails may be made to look like parcel delivery notifications or order confirmations. Senders claim that the file attachments are important documents that need to be reviewed urgently, which can alarm users enough to open them. Once the malicious files are opened, the malware can begin its malicious activities. However, in most cases, generic malicious emails are not difficult to recognize. The most noticeable signs are grammar and spelling mistakes in emails that are supposed to be sent by legitimate senders. For whatever reason, malicious emails are often full of such obvious mistakes.

You should also always take note of how an email addresses you. If you are addressed as User, Member, Customer, etc., instead of your name by a sender whose services you use, that should be suspicious. Companies generally use customers’ names when contacting them to make the emails seem more personal. Malicious actors target many users with the same email so they use generic words to address users.

It should also be mentioned that when users are targeted in individual attacks, the methods will be much more sophisticated. Malicious emails would be mistake-free, contain information that would give the email credibility, and just generally seem more legitimate. This is why users always need to be cautious with emails that have attachments. It’s recommended to scan all unsolicited email attachments with anti-virus software or VirusTotal before opening them.

Malicious infections are also prevalent on torrent websites because those sites are poorly moderated. It’s especially common to find malware in torrents for entertainment content, such as movies, TV series, video games, etc. If you use torrents to download copyrighted content, you’re not only stealing content but also putting your computer/data in danger.
