To enable a keylogger is exceptionally easy with native applications: Windows has SetWindowsHookEx(WH_KEYBOARD_LL... The problem is to follow the focus of the windows and parse out relevant information to send because logging all presses will be to obvious if you read memory or disk. Then you need to encrypt the data before you send it over the network, this is probably why all modern anti-viruses block all native HTTP traffic. The scary part is that the Windows API allows for a process to gather all keypresses even when the app window has lost focus?! To answer the question: open the exe in any text editor and search for SetWindowsHookEx... if it's there you know that exe can listen to everything.
