What is '.dian File Extension' Ransomware?
If you have found your files marked with .dian and could no longer open any of them, there is no doubt that '.dian File Extension' Ransomware, a nasty malicious application, has entered your computer and made modifications on it so that it could obtain money from you. This infection encrypts all popular formats of pictures, documents, and other files users usually consider the most valuable, so you will soon find out about the successful entrance of this ransomware infection if it ever shows up on your computer. Are you reading this article because you have already detected it on your system? If the answer to this question is “yes”, you should not worry about those encrypted files now because the first thing you must do is to delete the ransomware infection from your system as soon as possible. You cannot keep its components on your system because you might accidentally launch this infection again and get even more files encrypted. Theoretically, it might be possible to unlock those files with the special decryption tool cyber criminals claim to have, but, of course, this tool will not be given to you for free. Actually, you might not get it even if you transfer the required money to cyber criminals, which explains why we do not recommend sending money to malicious software developers. We cannot promise that you could unlock your files, but we are sure that it might be possible to restore them without the decryptor – we will tell you more about that in the paragraphs that follow.
What does '.dian File Extension' Ransomware do?
'.dian File Extension' Ransomware acts as an ordinary ransomware infection. After slithering onto users’ computers successfully, it finds the location of pictures, documents, and other important files and then encrypts them all mercilessly. The file is encrypted if it contains the new extension .dian next to the original filename extension (e.g. .jpg). You should also be able to discover a new file ReadMeNOW.txt on your Desktop if the reason you cannot open your files is the entrance of '.dian File Extension' Ransomware because this infection drops this file into folders containing encrypted files. First of all, this text file makes it clear why files can no longer be accessed: “Your files have been crypted with AES-256 method.” Then, users are instructed to send an email to lnq@protonmail.com if they want to get their files back. Although the ransom note tells nothing about money, we are sure you will be told that you could unlock your files only with expensive decryption software. Do not purchase it from cyber criminals because you might not get it even if you send money to them. Most probably, not all the users could get their files back, but there is a way to restore the encrypted data for free – restore all those locked files from a backup. You must have this backup located somewhere outside your system, e.g., on a USB flash drive because a backup stored on the compromised machine has, most probably, been encrypted by '.dian File Extension' Ransomware too.
Where does '.dian File Extension' Ransomware come from?
Although there is not much information about the distribution of '.dian File Extension' Ransomware available, specialists at anti-spyware-101.com believe that this threat should not differ from similar infections classified as ransomware. To put it differently, it should be spread inside spam emails masqueraded as an important attachment in most cases. According to them, cyber criminals might use other methods to spread this infection too. For example, it might be uploaded on a P2P website. As a consequence, you should not only stay away from spam emails you receive, but also do not download applications from dubious websites. It is not a piece of cake to prevent the ransomware infection from entering the system in all the cases, we have to admit, so we suggest that you leave this job for a trustworthy antimalware tool.
