One of the most recent Djvu/STOP ransomware versions is the Eiur ransomware. The malicious actors operating ransomware release new versions regularly, with Eiur, Llqq, Jhgn, Llee, and Lltt being among the more recent ones. This version can be identified by the .eiur extension added to encrypted files. It will encrypt all your personal files, essentially taking them hostage. You will not be able to open these encrypted files unless you first use a specific decryptor to decrypt them. Unfortunately, acquiring the decryptor will be challenging because only the malware operators have it. They will, however, try to sell it to you for $980. And paying is not recommended because it does not guarantee a decryptor.
As soon as you open an infected file, the ransomware will start encrypting your files. Your photos, videos, documents, and other files will all be targeted. Essentially, because they are the most valuable, all of your personal files will be encrypted. The extension that has been added to the files will allow you to tell which ones have been encrypted. This specific ransomware adds .eiur. So, a text.txt file that had been encrypted would become text.txt.eiur. All files with this extension will be unopenable. A _readme.txt ransom note will also be dropped by the ransomware. How victims can get a decryptor is explained in the note, and unfortunately, the malware operators want $980 for it. Although it’s doubtful whether it’s actually true, the ransom note also mentions a 50% discount for victims who contact the cyber criminals within the first 72 hours. It is not recommended to pay the ransom and/or communicate with the cybercriminals because there’s nothing to guarantee that you will get the decryptor even after paying. Keep in mind that you are dealing with cybercriminals, and nothing will stop them from simply stealing your money and not sending you a decryptor.
Use anti-malware software to remove Eiur ransomware from your computer. It’s a rather complicated infection that needs to be eliminated with professional software. As soon as the ransomware has been eliminated from your computer, you can connect to your backup and start recovering your files.
Users who did not make a backup of their files before the ransomware attack will find that file recovery is far more difficult, if not impossible. There is the option to wait for a free Eiur ransomware decryptor to be released, albeit it is unknown when or even if this will happen. Ransomware infections from the Djvu/STOP family use online keys to encrypt files, and this means the keys are unique to each victim. And those keys are necessary for a decryptor. So unless the keys are released by the cybercriminals themselves, a free Eiur ransomware decryptor is not very likely at the moment. Nonetheless, you should back up your encrypted files and occasionally check NoMoreRansom for a free Eiur ransomware decryptor.
Ransomware distribution methods
The developers of ransomware, and malware in general, use a variety of methods to spread the infections. Users that partake in risky behavior, such as opening unsolicited email attachments, clicking on advertisements while browsing high-risk websites, and torrenting pirated content, are more likely to infect their computers with malware.
If your email address has been leaked by some service, you will get emails with malicious attachments from time to time. As soon as you open the attachment, malware will initiate. This is why it’s so important that you always double-check all unsolicited email attachments before opening them. You can do that using anti-virus software or VirusTotal. But most of the time, malicious emails are pretty obvious in any way. One of the most obvious indications is grammar and spelling mistakes in what’s supposed to be a professional email written by a company whose services you use. Another indication is an email addressing you as User, Member, Customer, etc. when your name should be used. Legitimate emails with attachments you’d need to open will always address you by your name.
Lastly, because torrent sites are notoriously badly unregulated, they are perfect for spreading malware. Using torrents to pirate copyrighted content is very dangerous because many torrents for movies, TV shows, and video games often contain malware. And keep in mind that torrenting copyrighted content is effectively theft.
How to delete Eiur ransomware
Given that ransomware is a very sophisticated malware infection, attempting to manually remove Eiur ransomware is not recommended. If you’re not careful, you can unintentionally damage your computer even more, or you might not completely remove all ransomware components. The ransomware may be able to recover if you still leave some components. And if you attempted to access your backup while the ransomware was active on your machine, your backup files would also become encrypted. We strongly advise using anti-malware software to delete Eiur ransomware. You can safely connect to your backup to begin restoring files once the ransomware has been removed.
