Join Malcolm Shore for an in-depth discussion in this video Using callbacks to capture keystrokes, part of Cybersecurity Foundations.
- I'll now look at how we build a program…which uses a more sophisticated means of hiding,…by looking at a simple malware function,…written as a Windows process,…to intercept all key strokes.…In Microsoft Windows,…when a key on the keyboard is pressed,…an event is signalled to the operating system.…Windows uses its keyboard driver to read the character…that's been pressed,…and send it as a message to the application…that's waiting for it.…However, Windows also allows other processes…to look at the message as it passes through the system.…
That's how hotkeys work.…Windows does this by using something known…as a Keyboard Callback Routine.…It hook the key that's been pressed,…and then calls back after processing…to pass it on to its original destination.…This technique can be used to write…what's known as a simple keystroke logger.…This only takes a few lines of code,…but it's quite powerful.…The first thing I need to do…is write a program which includes a keyboard hook…callback routine…to take a copy of the keyboard input…
By the end of this course, you'll have a greater understanding of the threats that affect private, corporate, and government networks, and the knowledge to prevent attacks and defeat them.
