Threat: Trojan.Win32.Platinum.gen
Vulnerability: Arbitrary Code Execution
Description: The malware looks for and executes DLLs in its current directory. Therefore, we can potentially hijack a vuln DLL execute our own code, control and terminate the malware. 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.
