  • Detection of key logging software
    Patent number: 7823201
    Abstract: Installing a detection hook function aids in the detection of keylogger software on a computer. A request to install a hook procedure via the system service function is intercepted by the detection hook function. The detection hook function determines whether the request indicates that the hook procedure is keylogger software. If so, an action is taken such as denying the request or alerting the user. A detection hook function also intercepts a request to remove a hook procedure. A dynamic detection function intercepts a call to a hook chain function attempting to pass an event to a hook procedure.
