One of the most recent Djvu/STOP ransomware variants is the Uyro ransomware. The version can be identified by the .uyro extension added to encrypted files. All of your personal files will be encrypted by this ransomware, with the malware effectively taking your files hostage. You would first need to have a specific decryptor in order to be able to open the encrypted files. However, obtaining a decryptor will be difficult because only malware operators currently have it. It will be offered to you for $980. But paying the ransom is quite risky and comes with its own issues.


Uyro ransomware note



The Uyro ransomware primarily targets personal files, such as photos, videos, and documents. Knowing which files have been encrypted will not be difficult because of the .uyro extension that is added. As an example, text.txt would be converted to text.txt.uyro if encrypted. Without using a decryptor on them first, files with this extension will be unopenable. Each folder containing encrypted files will have a _readme.txt ransom note dropped by the ransomware and it explains how to get the decryptor.

Uyro ransomware files

The decryptor for the Uyro ransomware costs $980, according to the ransom note. The ransom note goes on to say that victims are allegedly entitled to a 50% discount if they get in touch with cyber criminals within the first 72 hours. However, that’s not necessarily true. The note further states that if a file does not contain any sensitive information, victims can decrypt one file for free.

Unfortunately, since you are dealing with cyber criminals, there is no guarantee that even if you pay the ransom, you will get a discount or a decryptor. Malware operators are unlikely to feel compelled to send the decryptor to victims even if they pay. In addition, the money collected from victims would be used to fund other criminal activities.

Uyro ransomware victims without backups won’t be able to restore their files without paying the ransom because there is currently no free Uyro ransomware decryptor. Malware versions from the Djvu/STOP family use online keys for file encryption. This means that every victim has a unique key. A decryptor wouldn’t be able to decrypt your data without your unique key. Therefore, a free Uyro ransomware decryptor might not be released unless those keys are first made public. We should note, however, that it’s not impossible for this to happen. If a free Uyro ransomware decryptor is ever released, NoMoreRansom will have it.

You must be extremely cautious while looking for a free Uyro ransomware decryptor because there are numerous fake or even malicious decryptors available. Another malware infection could happen if you download the wrong one. There probably isn’t a free decryptor available if you can’t find it on NoMoreRansom or another reliable site. It most surely won’t be available on any of the dubious forums that you will come across while searching.

If you have a backup of your data, you can start restoring files as soon as you remove Uyro ransomware. We do not recommend attempting to manually remove Uyro ransomware unless you are completely confident in your ability to do so. The process can be extremely complicated, and a mistake could lead to additional issues. Anti-virus software is considerably simpler and safer to use.

How does ransomware enter computers?

If you have bad browsing habits, a malware infection is much more likely, particularly if you use torrents to illegally download copyrighted entertainment content, open unsolicited email attachments, click on random links, etc. If you wish to prevent malware infections in the future, it is well worth your time and effort to develop better browsing habits.

Email attachments are a common method used by cybercriminals to deliver malware. They purchase hundreds of leaked email addresses from hacker websites and forums to use in their malicious email campaigns. Emails with malicious attachments would be sent to users whose email addresses were acquired from these forums. Malware is initiated and given the authorization to carry out its malicious actions when users open the malicious files.

Since malicious emails are typically quite generic, if you know what to look for, you should be able to identify them rather quickly. The most obvious indicators of a malicious email are grammar and spelling mistakes. Malicious senders frequently pose as representatives of legitimate companies whose services users use, but grammar/spelling mistakes immediately reveal the email for what it is. Legitimate businesses try to avoid spelling and grammar mistakes when communicating with customers because they come across as very unprofessional.

Another warning sign is when you receive emails that refer to you as “User”, “Member”, or “Customer” when your name should be used. In order to make emails feel more personal, companies automatically insert their customers’ names into emails. But since malicious actors usually can’t access sensitive information, they use generic language.

It’s important to keep in mind that some malicious email campaigns can be considerably more sophisticated. When they have access to someone’s personal information and are specifically targeting them, the email could look very convincing. A sophisticated malicious email wouldn’t have any grammar or spelling mistakes, would use the recipient’s name, and would even include some specific information that would give the email more credibility. It is strongly recommended to scan all unsolicited email attachments with anti-virus software or VirusTotal before opening them because a sophisticated malware email would be difficult to detect.

And finally, torrents are commonly used to spread malware. Because torrent websites frequently lack enough moderation, it is simple for malicious actors to submit torrents that have malware in them. Using torrents to download copyrighted content dramatically raises your chances of coming across malware infections. Malware is frequently found in entertainment-related torrents, especially those for video games, TV shows, and movies.
