Troj/Gina-K is a Trojan for the Windows platform.
When run, the Trojan copies itself to the Windows system folder as kxrnxl32.dll and sets the following registry entries:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows
AppInit_DLLs
"<Windows system folder>\kxrnxl32.dll"
The Trojan steals Windows login credentials and may run processes as other users.
