Research & Analysis of Flocker Ransomware
Flocker Ransomware is so nasty that it hides its code within raw data files in the “assets” folder having “form.html” as file name. Thus it appears to be quite normal file and it easily escapes detection when static code analysis is performed. However, as soon as the ransomware executes its malicious codes by decrypting “form.html” the files get locked. The first thing which Flocker Ransomware does, it detects the location of the device if it is executed for the first time. So this malware is region specific and does not infect devices of Eastern European Countries and areas around the vicinity. This makes it quite unique in its action. If it detects the device is located in the Countries like Georgia, Ukraine, Bulgaria, Azerbaijan, Kazakhstan, Russia etc, it does not infect the devices and deactivates its codes. However, if the targeted device does not belong to these locations and is preferably of different location then it is most vulnerable for Flocker Ransomware attack. It waits until 30 minutes to fully activate itself by running and executing its Routine. Thereafter, it seeks admin privileges of the device by initiating the background services. This is nothing but the trick to trap users and make them victim for paying ransom. As soon as the request is denied by the user, the device freezes requiring for update.
