They are the Alien Cables from Hacker Space.

Imagine a charging cable which looks exactly, and I mean exactly, like any stock charging cable. Oh, just one difference. This charging cable has built-in Wi-Fi and can run penetration programs on whatever it is plugged into.

Hacked charging cables exists, in four versions and two colors, white and black, and they sell for $119.99.

Ostensibly, they are “built for covert field-use by Red Teams.” However, anyone can buy one. We did. Determining if the following claims are true is important to protecting our clients.

  • “It looks like the real thing. It feels like the real thing, down to the millimeter.”
  • Has “features that enhance remote execution, stealth, and forensics evasion.”

Our tests revealed the hacked charging cable lived up to its claims.

Basically, this is a malicious wireless implant for computers. It’s a rigged USB cable that allows remote attackers to attack via Wi-Fi.

When plugged into a computer the operating system detects the cable as a Human Interface Device (HID), for example a keyboard.

The cable can broadcast its own Wi-Fi SSID acting as an access point, or it can be preconfigured to connect to a predetermined Wi-Fi network and act as a client, meaning it can use your network to hop on the internet.

Connecting to a predetermined network makes the cable even more difficult to detect. And, it may allow an attacker to open up a reverse shell to a remote computer where the attacker can issue commands. Simply speaking, the remote hacker has full access to your device.

Have your charging cables been switched? 
Have you thought to check? Probably not.

How to Identify a Hacked Charging Cable?

Our TSCM team worked on the problem…

The cable’s Wi-Fi signal is stealthy, but it can be detected. Wide areas of offices space can be scanned quickly if you know the revealing characteristics.

As in War of the World’s, the invader has an Achilles heel. Electronic circuits generate heat. This Martian is no different. When plugged in and operating the USB-A side of the cable measures between 115º and 125º Fahrenheit.

Although an infrared camera can identify these aliens you don’t need Men in Black capabilities like this. Just touch the plug. If it feels warm you’ve got big problems, and you need to call us.

Prevention Tips

  • Check Apple’s guide to fake cables.
  • Mark your cables with an indelible pen.
  • Use a USB wall charger instead of your computer.
  • Conduct TSCM inspections which include your Wi-Fi. In addition to finding killer cables, inspections find other rogue devices as well.

If you have any questions, or would like to schedule a TSCM information security audits for your office or home, just let me know.
