Qlln ransomware comes from the notorious Djvu/STOP malware family and is a type of malware that encrypts files. Once files have been encrypted, you will not be able to open them unless you first use a decryptor on them. Encrypted files can be identified by the .qlln extension, all personal files will have it. Unfortunately, the only people who have a decryptor are the cybercriminals operating this ransomware. They will try to sell it to you for $980. But considering that cybercriminals are notoriously unreliable, paying is very risky because it does not guarantee that a decryptor will actually be sent.
As soon as you open the malicious file and initiate the ransomware, Qlln ransomware will begin encrypting your personal files. Your photos, documents, videos, and other data will be targeted because they’re most valuable. You can quickly identify which files have been encrypted by the.qlln extension. For instance, text.txt would be changed to text.txt.qlln when encrypted. These files require a particular decryptor in order to be opened. A way to get the decryptor is described in the _readme.txt ransom note. Unfortunately, a $980 ransom is demanded from you. Although it’s questionable whether it’s actually true, the note mentions a 50% discount for users who contact the cyber criminals within the first 72 hours. But since there are no guarantees that the cybercriminals will actually send you the decryptor, paying the ransom is not recommended. You might end up with not only encrypted files but also lost money. Furthermore, your money would go towards future criminal activities if you paid.
We strongly recommend using anti-malware software to remove Qlln ransomware from your computer. Considering that it’s a very serious infection, you should not try to get rid of it manually because you might cause additional damage to your computer. Once the ransomware is gone, you can start file recovery from backup.
If you did not back up your encrypted files prior to infection, you may not be able to recover them. Your only option is to back up the encrypted files and wait for a free Qlln ransomware decryptor to be released. It’s not certain whether one will actually be released because this ransomware uses online keys to encrypt files, but it’s not impossible. The problem is that online keys mean that the keys are unique to each victim. Unless those keys are released by the cybercriminals themselves (or by law enforcement if they were to catch the cybercriminals), a free Qlln ransomware decryptor is not very likely. Nonetheless, if you’re out of options, back up encrypted files and occasionally check NoMoreRansom for a decryptor.
Ways ransomware is distributed
Malicious actors frequently use email attachments to distribute malware. You will, from time to time, receive malicious emails if your email address has been leaked in the past. You can check on haveibeenpwned if it’s been leaked. If your email address has been part of a data breach, you need to be extra careful with emails that have attachments. Avoid opening any unsolicited email attachments without double-checking them first. You can scan them with anti-virus software or VirusTotal before opening them. You can also often recognize malicious emails. Senders often pretend to be from legitimate companies, supposedly emailing their customers. But these emails look very unprofessional, which immediately gives them away. The emails are full of grammar/spelling mistakes and address users with generic words like User, Member, Customer, etc. Grammar/spelling mistakes are incredibly unprofessional in official correspondence. And legitimate emails will also address users by their name, not generic words.
Many torrent websites are very poorly regulated, allowing malicious actors to upload torrents with malware in them. It’s especially common to find malware in torrents for entertainment content. In particular, popular movie, TV series, and video game torrents are often full of malware. If you use torrents to download copyrighted content for free, you’re risking picking up a malware infection that can cause quite a lot of damage. And as you already know, pirating is essentially stealing content.
Qlln ransomware removal
Due to ransomware’s complexity, it is not recommended to remove Qlln ransomware manually. If you’re not careful, you could end up causing even more damage to your computer. Additionally, you might miss some ransomware components, which might allow it to subsequently recover. If you access your backup while ransomware is still running on your computer, your backed-up files would become encrypted as well. Instead, you should use professional anti-malware software to delete Qlln ransomware from your computer. As soon as Qlln ransomware has been completely removed from your computer, you can connect to your backup to start recovering your files.
