Original source:  
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.  
Family: PlatinumGroup  
Type: PE32  
MD5: 71a76adeadc7b51218d265771fc2b0d1  
Vuln ID: MVID-2022-0657  
Dropped files: Adobe_Update_Sync.exe  
Disclosure: 11/18/2022   
1) Compile the following C code as "WTSAPI32.dll"  
2) Place the DLL in same directory as the malware  
3) Optional - Hide it: attrib +s +h "WTSAPI32.dll"  
4) Run the malware  
#include "windows.h"
