DevNightmare Ransomware is a malicious program that is actually true to its name as it can truly become a nightmare for you if it manages to slither onto your computer. Strangely enough, we have dual feelings about this infection. On the one hand, it seems like it was authored by an amateur judging by the quality of the ransom note. On the other hand, we have found that this ransomware is built on the infamous open-source Hidden Tear Ransomware. In any case, this ransomware can definitely leave its mark on your computer with the encryption of your files since there is no file recovery tool available on the Internet yet to help you decode your files. There are two possibilities for you. One, you pay the demanded ransom amount to the author of this attack, who could be acting alone this time. Two, you transfer your backed up files that you store on a removable drive back to your hard drive. Of course, there is no guarantee that you will get anything for your money. So it is up to you whether you want to still risk paying or not. Nevertheless, we believe that it is best if you remove DevNightmare Ransomware from your system because this is the only way for you to secure your computer.

Ransomware attacks usually target gullible computer users who can be tricked into opening spam e-mails. Contrary to the spamming campaigns of the past, though, nowadays criminals are much more sophisticated and are usually at least one step ahead of spam filters. This is why it is quite easy to be fooled. DevNightmare Ransomware is spreading as a malicious attached file in spam e-mails. This file always pretends to be something else than it really is. For example, you may think by the look that the attached file is an image of an urgent invoice, or a document claiming to be a wrongly placed order or a booking of some kind. The subject of the mail also manages to make you believe that you are actually dealing with an important-to-see message as well as attachment. Since this spam ends up in your inbox, you would normally not doubt its authenticity and reliability; well, maybe not until now. As you can see, you need to be much more cautious when you browse through your inbox. If you see any questionable mail that just does not sound related to you, it would be wise to double-check the sender and if the attachment was really meant for you. This way you could decrease the possibility of getting infected with such a serious threat. Because one thing is sure: if you delete DevNightmare Ransomware after it has finished its vicious job, there may be no way for you to recover your precious files. Therefore, prevention is of utmost importance when it comes to ransomware programs. In fact, the best way for you to protect your computer from similar dangerous threats is to install a proper anti-malware application.

After you launch this threat by running the downloaded file, it targets your personal files, such as your pictures, videos, music files, databases, and so on, and encrypts them with the AES-256 built-in Windows algorithm. Your files will get a new extension, ".2xx9," changing the file names to something like "mypicture.jpg.2xx9." If you find out that your files have this extension, you can be sure that you have been hit by this severe infection. As a matter of fact, there is no other way of telling that your files have been taken hostage, apart from the fact that you cannot open any of the encrypted files anymore. This ransomware does not pop-up a scary ransom note image on top of all your active windows and neither does it lock your screen in any other way.

DevNightmare Ransomware simply creates a text file, "READ_ME.TXT," on your desktop, which you have to open yourself if you want to understand what has caused the current situation. As we have already mentioned, this note seems to be rather amateur. It is written with broken English and also sounds quite vague about the ransom fee. The author simply states "Send me some money or bitcoins," which you cannot really call specific or even a serious demand. It sounds more like someone wanting to make some easy money for the first time this way; but definitely not the master piece of a proper cyber crook. According to the instructions, you are to send an e-mail to if you want to get your files back. It is possible that you will get more detailed information about the ransom fee transfer in the reply message because otherwise it could be a bit tricky to comply with the demands. But before you rush to transfer the money, which could be anything between 60 to 600 US dollars worth of Bitcoins, you should consider a few things, but mainly that you are dealing with a criminal who may not keep his promise. Sending any money would simply support such a crook or crooks to commit more online crimes. We suggest that you remove DevNightmare Ransomware the moment you realize what has happened.

Finally, let us help you with the solution. First, we must mention the importance of regularly making backup copies of all your important files so that you could use them in similar situations without the nightmare of losing them for good. Second, if you want to defend your machine against all kinds of malware threats, perhaps it is time for you to invest into a decent malware removal tool, such as SpyHunter.
