Keyloggers are great, but wouldn’t it be better if you could transmit your victims’ keystrokes wirelessly? Using a PIC controller, and your computer’s PS2 keyboard port, you can stream keystrokes using an inexpensive radio frequency transmitter and receiver. This is definately a great addition to our how to be a covert spy tutorial.
How it works:
The receiver receives the signals, and farts out a datastream. This is in the form of 0 to 5v pulses, which your PC’s serial port can’t understand. The max233 converts the 0 to 5v signal into a +/-10v signal so the serial port is happy. These go to pin 2 on the connector, which is the receive data pin for the serial port. Read more.
