At the Def Con conference, hacker and developer Michael Grover, aka MG, showed an O.MG Elite cable with a built-in web server, USB power, Wi-Fi access, and keylogger.

It allows you to hack into PCs and smartphones and then monitor their operation, simulate keystrokes or enter commands. Almost all current operating systems are supported.

This is already the second version of the cable, it is able to send and receive data wirelessly. The first version had a Wi-Fi access point, but its capabilities were limited.

O.MG Elite allows intercepting keystrokes, launching attacks or actions using the console, downloading malware or stealing saved passwords from a browser and transmitting them to an intruder via the Internet. There's also a keylogger that monitors keystrokes and can save up to 650 thousand records in the cable's own memory.
