The O.MG cable is a $119 iPhone cable with a dirty secret: embedded inside it is a web server and keylogger that can literally steal the keystrokes right from your computer.
From the product page:
Every O.MG Cable is hand made and tailored to look and feel exactly like the cable your target already has in their possession. You won’t need a million dollar budget for this cable, but the power and capabilities are extensive.
It is packed with a web server, 802.11 radio, and way more memory and processing power than the type of cable you would want for just doing demos. But the flexibility makes demos easy.
Basically, someone puts this into their computer and their entire system can be comprimised. The USB port becomes an access point that allows a hacker to mess around with almost any machine, all from the comfort of a distant web browser. It also has an autodestruct feature that will shut down the cable in case of emergency.
A keylogger version for keyboards costs $159 and can grab 65,000 keystrokes before needing to be “emptied.”
How can you protect against the O.MG cable? These little dongles ensure that your devices – or this cable – don’t connect to your computer and can only charge via USB. That said, if someone is using this aganst you you’re probably sunk anyway.
