The DJVU ransomware is making its presence felt since December 2018. Encrypting files from thousands of Windows OS, the DJVU family is back with this new strain – Davda Ransomware.
Once, this ransomware attack the system, it immediately looks for the targeted files. The files which are targeted are commonly found on most Computers these days. It includes audio – video files, images, document files and what not!
Hence, following are a few extensions, which are targeted by Davda Ransomware virus: .docx, .pdf, .html, .txt, .jpeg, .png, .gif, .mp3, .mpeg, .mpg.
After corrupting the targeted files, a ransom demanding message is generated in ‘readme.txt’ file.
As a result, the victim is forced to pay the money, in order to restore the files.

After successful infiltration, Davda ransomware scans every inch of your system to find the targeted files. This ransomware encrypts the files and appends a unique extension to them. Davda extension is attached to the encrypted files, which makes them unusable. The ransomwares of DJVU family delivers the same ransom note after the file encryption and Davda is no exception.
At the same time, an additional file, named “readme.txt” is generated in every folder containing the encrypted file. This text file contains the ransom demanding message.
Unfortunately, a unique decryption key is generated while encrypting the files. This key is created on the hacker’s server and large amount of ransom is demanded in its exchange. Once the files are corrupted, restoring them manually is next to impossible task. Hence, the victim is bound to pay the asked ransom.
Hackers are smart now-a-days and know how to fiddle with the minds of their victims. As Bait, they allow users to send one encrypted file to them! To gain the trust, Hackers decrypt this sample encrypted file and send it back to the user! The moment user falls for the bait and makes the payment, he / she is often left ignored by these hackers!
As a smart user, you should avoid falling in such luring claims and instead search for a full-proof Davda ransomware removal method from your system.
