Traffic Light System Can Be Hacked

Traffic Light System Can Be Hacked

The vulnerability found conducted by a team led by J. Alex Halderman, computer scientist at the University of Michigan

According to a paper researchers presented at the Usenix security conference in San Diego, in some cases, the controllers are part of an interconnected system and may communicate via radio frequency.

Halderman and his team found that the controllers could be set up remotely, via an FTP connection to a configuration database.

The actions supported by the controller include not just changing the lights based on an “if-then-else” logic, but also freezing them.

Attackers can control the lights as they wish, changing colors according to their needs
