masterbuster-ransomware-note-image-bss

The MasterBuster ransomware is new variant of the open-source ransomware project Hiddentear. The first malware samples were discovered this month (October 2016) being delivered with a Bengali ransom note which means that the operators of the code are probably from Asia.

Upon infection the virus encrypts target user data with a strong cipher and appends the HCKED extension. The interesting thing in this iteration of HiddenTear is that the hackers request the users to fill out a form in Google Sheets as part of the ransom sum payment process. The request sum is 3500 ruppees, if the user delays payment for more than 10 days then it is increased to 5000 to 10000 rupees.

The ransomware operators also allow payment via various options – Bkash, Dutch-Bangla Mobile Dank and others.
