'.dian File Extension' Ransomware is a highly malicious computer infection that can encrypt many of the files on your PC and offer you to buy a decryption tool to decrypt your files. Its creators want to extort money from you and you should not allow that to happen. Therefore, we recommend that you remove it from your PC as soon as you can. In this short description, we will discuss how this ransomware works, how it is distributed, and how you can get rid of it. To our knowledge, there is no free decryption tool available for this ransomware yet. So your options are to either pay the ransom and risk losing money or delete it.

This ransomware claims to use the Advanced Encryption Standard (AES) to encrypt your files. It uses a 256-bit length key which ensures a strong encryption. This ransomware is set to encrypt your most valuable files such as your documents, pictures, videos, and audio files. It appends the encrypted files with a “.dian” file extension. This extension acts as a file marker. We believe that this ransomware creates a public encryption and private decryption keys and the decryption key is sent to a remote server. Thus, you cannot obtain it without paying the ransom. Still, paying it is a risk because its creators might not send you the promised decryption.
Once the encryption is complete, this ransomware is set to drop a ransom note into each folder where files were encrypted. The note is called ReadMeNOW.txt and it is a simple text file that says that your files have been encrypted with AES-256. The note says that you need to contact the cyber criminals by sending a message to firstname.lastname@example.org. Then, you will receive further instructions on how to pay the ransom. The criminal offer you proof that they can decrypt your files by offering you to send one file that is no more than 2Mb of size, and they promise to send you the file back decrypted. Still, there is no reason trust the cyber criminals even if they send you a decrypted file.
Truth be told, '.dian File Extension' Ransomware can be distributed using many methods. We believe that the most likely case is that it is sent in malicious emails that have it attached as a PDF document. The email can claim that it is a tax return form or some sort of receipt from a well known company, but that is a lie. If you open the attached file, then this ransomware can infect your PC. Furthermore, it is also possible that this ransomware is bundled with pirated software and distributed via torrent sites and sites dedicated to distributing pirated content. Also, the developers can use exploit kits featured on infected websites that can infect your PC when you interact with Java or Flash content.
