Btnw ransomware is a file-encrypting malware, one of the most recent Djvu/STOP ransomware versions. The cybercriminals operating this ransomware regularly release these updated versions, with Btnw ransomware being among the most recent ones. This malware is very dangerous despite being fairly generic. It will encrypt your personal files once it enters your computer, effectively holding them hostage. You will be asked to pay a ransom by the ransomware operators, but you should be skeptical because paying does not ensure that your files will be decrypted.


Btnw ransomware note


Although the majority of ransomware variants from the Djvu/STOP malware family are quite similar, you can tell which variant you are dealing with quite easily because they add different file extensions to encrypted files. This ransomware adds the .btnw extension, hence why it’s dubbed Btnw ransomware. This extension will be added to all encrypted personal files, including photos, videos, and documents. Without first using a decryptor on them, you won’t be able to open any of these encrypted files. The only people who have the decryptor are the hackers operating this ransomware, therefore obtaining it won’t be simple. They won’t just hand it over to you; instead, they’ll demand a ransom payment. The _readme.txt ransom letter that is dropped in folders containing encrypted files has instructions on how to obtain the decryptor.

The ransom note, _readme.txt, is nearly identical to those left by other versions of this ransomware family. The contact email addresses are the only things that change. The ransom note explains that you must pay a ransom to obtain the decryptor. The email does say that there is a 50% discount for victims who make contact during the first 72 hours but the regular decryptor price is $980. The discount part is questionable, as is the whole paying the ransom process. Because there is nothing to force cybercriminals to uphold their half of the bargain, it is not a good idea to put your trust in them. If you pay the ransom, the cybercriminals can just take your money and not send you anything in return. Unfortunately, many users have experienced this in the past, and it will probably continue to happen frequently. Whether to pay or not is your choice to make but you do need to take into account all the risks involved.

Your files are easily recoverable if you have a backup. However, you first need to fully delete Btnw ransomware from your computer before you can safely access your backup. It’s highly recommended to use anti-virus software to remove Btnw ransomware because otherwise, you could end up causing even more damage to your computer. You should only attempt manual removal if you are fully confident in your abilities. You can start restoring files from your backup once the ransomware has been removed from your computer.

Users without backups have no choice but to wait for a free Btnw ransomware decryptor. But it’s uncertain whether one will be made available. Btnw ransomware and other Djvu/STOP family ransomware versions encrypt files using online keys, which means they are specific to each victim. A free Btnw ransomware decryptor is not very likely until those keys are released by the crooks themselves (which is not impossible) or if they are ever captured by law authorities. A free Djvu/STOP decryptor made by Emsisoft is available, but it likely will not work on Btnw ransomware and other more recent Djvu versions. But it’s worth a shot.

Ransomware distribution methods

Users that engage in dangerous activities while browsing are far more likely to become infected with malware. This includes downloading copyrighted content via torrents, clicking on advertisements when visiting risky websites, and opening unsolicited email attachments without checking them first. Developing better browsing habits now will help you avoid infections in the future.

Email attachments are one of the simplest ways for cybercriminals to spread ransomware. From numerous hacker forums, malicious actors purchase email addresses, attach a malicious file to an email, and send it. As long as the files are not opened, the emails are not particularly dangerous. But opening the infected file would initiate the ransomware on your computer. However, most of these emails are quite poorly written, making it very simple to identify them for what they are. When senders pose as representatives of legitimate companies yet their emails are full of spelling and grammar errors, it is extremely obvious that the email is not what it first appears.

You can get a sense of whether an email is malicious or not by looking at how the sender addresses you. It’s likely a malicious or at least a spam email if the sender claims that you use their services yet uses terms like “User”, “Member”, “Customer”, etc. to address you. Customers are typically addressed by their names in emails, so you should be extremely suspicious if an email asks you to open an attachment without using your name. Also worth noting is that some malicious emails may be more sophisticated in some cases. Therefore, it is advised to always check any unsolicited email attachments with VirusTotal or anti-virus software before opening them.

Another effective method for malware infection is through torrents. As you are probably already aware, torrent sites frequently lack enough regulation, making it simple for malicious actors to post torrents with malware in them. Torrents for well-known movies, TV shows, video games, software, etc. frequently contain malware. The likelihood that its torrent contains malware increases the more popular the content is. Pirating copyrighted content is essentially stealing, and it can be harmful to your computer and data so keep that in mind.
