Mool ransomware is a part of DJVU/STOP malware that infects Windows computers and locate important files or documents of target victims. Mool encrypts the data using their strong algorithm and locks it in order to be inaccessible. As a ransomware, Mool demands a ransom fee in exchange for decryption tool and necessary private key.
Mool file infection
The ransomware uses complex algorithm to encrypt target files. Then, it adds the .mool file extension to every infected data. For example, the file draw.jpg will transform to draw.jpg.mool once encrypted. After that, victims will receive a ransom note from Mool in a text file named “_readme.txt”. It contains message of Mool authors stating instructions or procedures on how to recover the encrypted data.
Usually, Mool ransom fee would cost up to $980. However, hackers are offering a 50% discount with the condition of contacting them within 72 hours. Mool will instruct their victims to send an email to provided contact address attaching a copy of personal identification and one infected file to decrypt by them free of charge.
Believing that paying the ransom fee could recover the files; victims ought to settle the amount. Just like old variants as Rooe, Bboo, and Repp, Mool handlers usually preferred crypto-currency in their transactions, so the payment should be in Bitcoin.

Mool developers attach interesting files to caught attention of victims and open it. Not knowing that it is just a technique in order to inject the ransomware to system and start tracking important data.
