Tesla Motors Inc (NASDAQ:TSLA)’s Model S sedan is a technological marvel. However, all the technology is hidden from the owners who enjoy the wonderful driving experience. But some Tesla Model S owners have revealed that the small 4-pin connector on the left side of the dashboard is a stealth Ethernet port. Those who know hacking can get all the car’s secrets. A Tesla enthusiast said in a thread on Tesla Motors Club that the in-car network traffic can be seen through the Ethernet port.

Tesla Model S runs on a modified version of Ubuntu

According to Geek, the port is an HSD 4 pole M12, which has pins compatible with a standard Ethernet cable. Some Tesla Motors Inc (NASDAQ:TSLA) Model S owners used it to see various traffic types exchanged in Tesla’s systems. The Model S internal network has three devices: center console (, the navigation screen ( and a mysterious gateway device that nobody has pinned down yet (

There are many open ports that carry out various functions. For example, there is port 6000 for X11 services and port 80 for downloading navigation/media data. Users were able to run Firefox on the center console using X11 application forwarding. According to The Register, Model S runs on a highly modified version of Ubuntu and an old version of the mini-httpd Web server.

Tesla may bring third-party apps on the car

This kind of access may lead to jailbreaking the car. Hackers can modify the system and load it with third-party apps.
