Hackers Can Mess With Traffic Lights to Jam Roads and Reroute Cars

I remember back in pre-internet days when BBS file directories were filed with ways to hack stop lights via pulses from a strobe light. Supposedly if you had the right pulse (and the cojones to have a pulsing strobe light on the front of your car) you could mimic the pulse in a siren and get reds to start a process immediately to switch to greens. Different locations had different pulse timings and people would find local ones and upload and aggregate them on some local phreaking BBS&#x27;.<p>Never tried this myself.

&gt; “it was found that all communication is performed in clear text without any encryption nor security mechanism. Sensor identification information (sensorid), commands, etc. could be observed being transmitted in clear text.”<p>&gt; Because the sensors’ firmware is also not digitally signed and access to them is not restricted to authorized parties, an attacker can alter the firmware or modify the configuration of the sensors.<p>Who deploys systems out into the wild these days without even giving a moment of consideration to security? This seems like &quot;amateur hour&quot; systems design. Did not a single engineer step up and say &quot;Hey, uh, guys, do we want to at least take basic steps to obfuscate this stuff?&quot;<p>Sounds like negligence. Not surprising their vice president of engineering has &quot;nothing more to add to the matter.&quot;

That&#x27;s certainly a step up from the olden days, when hackers could turn your computer into a bomb and blow your family to smithereens.

Hmm maybe Live Free or Die Hard wasn&#x27;t all that far fetched.

With all the facial recognition software, I wonder why they just don&#x27;t put a camera on top of the light, recognize traffic coming, and optimize to maximize flow.

It&#x27;s even worse, hackers can mess with anything connected directly or indirectly to the internet.

This has civic benefits with traffic, safety, order. What&#x27;s not to like?

Immediately reminds me of Hackers 90&#x27;s movie and hackers establishing &quot;turf&quot; over public resources.
