Qapo ransomware is malware that encrypts files. It comes from the notorious Djvu/STOP ransomware family and is one of the newest versions. This version can be differentiated by the .qapo extension added to encrypted files. This ransomware will target all personal files, and once they’re encrypted, it will demand payment for a decryptor to decrypt them. File recovery shouldn’t be a problem for those who have backups. Those without backups, however, are unlikely to recover their files. Although paying the ransom is an option, it is not recommended because of the numerous risks involved, which will be discussed more in this article.


Qapo ransomware note


Most Djvu/STOP versions, including Qapo ransomware, are more or less identical to one another. However, they can be identified by the extensions they add to encrypted files. For example, this one adds .qapo. An encrypted text.txt file would become text.txt.qapo. Unfortunately, you will not be able to open any files that have the .qapo extension, unless you have a specific decryptor that only the malware operators currently have. And most of your personal files (e.g. photos, videos, documents, etc.) will have this extension because they are the main ransomware target.

The ransomware will leave a _readme.txt ransom note in each folder that has encrypted data. How victims can obtain the decryptor is explained in the note. According to the note, a ransom must be paid in order to get a decryptor. The decryptor is being sold for $980. However, victims who get in touch with cyber criminals within the first 72 hours are eligible for a 50% discount. Whether the discount part is true or not is debatable but it is not recommended to pay the ransom because it’s very risky.

You should keep in mind that you are dealing with cyber criminals, and even if you pay them, there is no reason why those who initially encrypted your files would feel any sort of obligation to help you. The ransomware creators frequently just steal the victims’ money without providing them with the decryptors. That has happened many times in the past. You are free to decide whether to pay the ransom, but we feel it is important to inform you about the risks that come with it. It’s also important to note that victims’ continued payment of the ransom is one of the factors contributing to ransomware’s increased prevalence nowadays. Ransomware would not be as widespread if all users regularly backed up their data because there would be no reason to pay the ransom.

As soon as you remove Qapo ransomware from your computer, you can begin file recovery if you have copies of your files in a backup. It’s important to use anti-malware software to delete Qapo ransomware because if you try to do it manually, you risk causing further damage to your computer. If you try to do it manually, you might not be successful in completely removing it, which could allow it to recover later on. Your backup files would become encrypted if you tried to access the backup while the ransomware was still active on your computer. For this reason, use a trustworthy anti-malware program to prevent causing more harm.

Unfortunately, your options are extremely limited if you don’t have a backup. The only choice is to hold out until a free decryptor is made available. Because this ransomware encrypts files using online keys, it is uncertain if a decryptor will be made available. It is challenging for malware developers to create a decryptor because the keys are unique to each victim. A free Qapo ransomware decryptor is unlikely to be developed unless those keys are released. Because it has happened before, it is somewhat possible that the cybercriminals themselves will eventually release the keys. Therefore, we advise you to make a backup of your encrypted files and check NoMoreRansom for a free decryptor occasionally.

Ransomware distribution methods

Email attachments are one of the most popular ways that cybercriminals spread ransomware. Thousands of email addresses are purchased by malicious actors from various hacker forums. After being exposed by services or as a result of a data breach, those email addresses end up on those forums. Malware-carrying emails typically contain attachments that if opened, would initiate the malware. Fortunately for users, these emails are typically extremely obvious because they’re full of spelling and grammar mistakes and just seem weird overall. Senders frequently claim to represent legitimate businesses whose services users use. Yet, the emails have obvious mistakes that you would not normally see in legitimate emails from legitimate companies.

Another indication that an email may be harmful is when a sender who should know your name uses generic words like User, Member, Customer, etc. Legitimate emails from companies whose services users use will always use users’ names to address them because it gives the emails a more personal feel.

It’s worth mentioning that there are considerably more sophisticated malicious email campaigns. Thus, a service like VirusTotal or anti-malware software should be used to scan all unsolicited email attachments before opening them.

Torrents are another method for distributing ransomware. Since torrent websites are notoriously poorly regulated, as you are probably already aware, malicious actors can easily upload malware disguised as torrents for popular content like movies, TV series, video games, software, etc. We strongly advise against downloading pirated content, especially using torrents, because doing so is risky for your computer and your data. It’s also essentially content theft.

How to remove Qapo ransomware

We advise against attempting to manually remove Qapo ransomware because you risk causing more harm. Using a good anti-virus program is a much better option because ransomware is a sophisticated malware infection that requires a professional program to remove. You can start file recovery after you fully delete Qapo ransomware from your computer by connecting to your backup.
