Computer Scientists Hack Michigan Traffic Lights To Show Security Flaws
With permission from a local road agency, researchers in Michigan hacked into nearly 100 wirelessly networked traffic lights, highlighting security issues that they say are likely to pervade networked traffic infrastructure around the country.
The team, led by University of Michigan computer scientist J Alex Halderman, found three major weaknesses in the traffic light system: unencrypted wireless connections, the use of default usernames and passwords that could be found online, and a debugging port that is easy to attack, reports MIT Technology News.
