Bttu ransomware is a generic ransomware infection, a variant of the Djvu/STOP ransomware. New variants of this ransomware family are released regularly by the cybercriminals who operate it, usually at least one or two new versions every week. There are currently hundreds of these ransomware versions, though they are very similar to one another. You can tell which one you are dealing with by the extension added to encrypted files. Your files will have .bttu added to them if your computer is infected with Bttu ransomware. Unfortunately, you might not be able to fully recover the files if you don’t have a backup. The malware operators will offer to sell you a decryptor for $980. However, paying is not advised because it does not ensure that a decryptor will be sent.
Bttu ransomware is the most recent Djvu/STOP ransomware version to be released by cyber criminals. This malware will begin encrypting your files as soon as you initiate it. It mainly focuses on personal files, such as photos, images, videos, documents, and so forth. The extension that gets added to encrypted files will let you know which files have been encrypted. It adds .bttu to be specific. An image.jpg file, for example, would become image.jpg.bttu. Unfortunately, unless you run a decryptor on them beforehand, you won’t be able to open any of these files. The _readme.txt ransom note provides instructions on how to obtain the decryptor.
The _readme.txt ransom note can be found in every folder that contains encrypted files. The note states that victims can buy a decryptor for $980. But supposedly, if users get in touch with the cybercriminals within the first 72 hours, they can get a 50% discount. Whether the discount part is true is not certain. But generally speaking, we do not recommend buying a decryptor from online criminals because there are no guarantees that you will get it. Keep in mind that you are dealing with cyber criminals, and nothing can stop them from simply taking your money without sending anything in return. Numerous victims have paid the ransom in the past but never received their decryptors. You decide whether to pay or not, but you should be aware of all the risks that come with it.
Users without backups will have a very difficult time recovering their files. Waiting for a free Bttu ransomware decryptor to become available is their only choice. However, because this ransomware uses online keys to encrypt files, developing one for malware researchers will be difficult. Online keys mean that each victim has a different key. For a decryptor to work on your files, your specific key is necessary. A free decryptor is not very likely until those keys are released by the malware authors. It’s possible that the keys may be released in the future, as has happened in the past. A free Djvu/STOP decryptor was also created by Emsisoft; although it’s unlikely to work in your case, it’s still worth a try. There are numerous fake and even malicious decryptors, so you should exercise caution when searching for them.
As soon as you remove Bttu ransomware from your computer, if you have a backup, you can open it to begin restoring your files. We strongly recommend using good anti-virus software. Avoid trying to do it manually because you can unintentionally do more harm.
How you can avoid a ransomware infection
Torrents, malicious emails with attachments, risky websites, etc. are common distribution methods for malware infections that target random users. Bad internet habits increase your chances of becoming infected with malware since you engage in risky activities more often. You may significantly lower your risk of getting malware by taking the time to develop better browsing habits and becoming aware of malware distribution methods.
It’s no secret that torrent sites frequently lack moderation, which results in torrents with malware in them being posted. All kinds of torrents often have malware in them, though it’s usually torrents for copyrighted content. The more popular something is, the more likely its torrent will contain malware. Malware is most often present in torrents for movies, TV shows, video games, software, etc. So it’s possible that this ransomware infected your computer when you used torrents to pirate copyrighted content.
You could have also opened a malicious email attachment, which would have allowed the ransomware to infect your machine. Ransomware is frequently downloaded by users through email attachments. The emails are typically easy to identify. The biggest giveaways are grammar and spelling mistakes. It’s rather clear that something is wrong when senders claim to be from legitimate companies but the emails are full of spelling and grammar mistakes.
Unsolicited emails containing attachments should always be examined carefully. Additionally, pay attention to how the sender addresses you. If you receive an email from someone who should know your name but they use generic words (e.g. User, Member, Customer) to address you, it’s likely that the email is malicious, or at least spam.
It’s worth mentioning that it’s a good idea to always scan email attachments with anti-virus software or VirusTotal before opening them because certain malicious emails might be more sophisticated.
How to remove Bttu ransomware
Trying to manually delete Bttu ransomware is not a good idea because you risk damaging your computer even more. Ransomware is a very sophisticated infection that should be left to a professional program. If you attempt to manually delete it, you might not be able to do it completely, which could allow the ransomware to recover. Your backed-up files would become encrypted if that happened while you were connected to your backup. Delete Bttu ransomware with anti-malware software to prevent causing additional damage to your computer. You can safely access your backup once the ransomware has been completely removed from your computer.
Your only choice may be to wait for a free decryptor to be released if you do not have backup copies of your files. Make a backup of your encrypted files and occasionally check NoMoreRansom for a free Bttu ransomware decryptor.
