Brief Description 

    

Keyhook.A is a Hacking Tool. Though these programs are legitimate and useful tools when they are appropriately used, a hacker could take advantage of them in order to carry out malicious actions.

Keyhook.A is a DLL (Dynamic Link Library) that provides two functions:

  • SetKeyboardHook: it activates the keystroke logging.
  • ReleaseKeyboardHook: it deactivates the keystroke logging.

Keyhook.A can be used by keyboard drivers or keyloggers, such as Trj/Keyhook.A.

Keyhook.A is not a risk by itself, but it can be used with malicious intentions.
