If you don't trigger the sensors, you might end up waiting forever. It's the same as if you were in a car! Motorcycles just don't weigh enough and you have to sit at intersections until another car comes behind you, because it doesn't know you are there. This is not a hack of any kind it just alerts the electrionics at the intersection that there is a vehicle there. That happened to my stepfather; he once sat at one of those on a motor-cycle.
He was there 11 min. Michaelmayo, that the longest bunch of crap i have ever heard, you wasted more time coming up with that then you ever will at a light.
Each loop is one wire wound up and then back to the control cabinet. They are only a couple inches in the roadway unless its be repaved. Flashing an infra-red will not set off the sensors for emergency vehicles and those sensors are only at key intersections. And they will not "auto overload". Wow could throw out some more lingo to try and convince everyone. And there are nooo loops for pedestrians.
Oh and the controllers in the traffic signal cabinets are no bluetooth ready idiot there is no usp port and you cant just walk up and flip them open, what a bunch of crap.
Ivrk is right michealmayo is an even bigger tard then xoebear! Nice solution. How about next time show an example with someone wearing proper gear? You know, helmet, gloves, boots, eye protection, pants, jacket. I once thought it would be cool to create a device that would delay changing the lights the opposite direction if there was a car in the intersection.
Turns out those jerks that give you tickets automatically when you run a light own the patent on that. So they rather give tickets then save lives, since most accidents occur when people run lights. Actually some of them are pressure sensitive. I made a test in france on bike and if i braked hard with front brake will add more weight on the front and press the force down on the front wheel and only waited 10 to 15 seconds instead of the times where i just came rolling at 20kmh and stopped slowly.
And theres also some of them with light sensors maybe for night recognition if lights are moving. Cerrudo started its analysis evaluating the architectures of traffic light systems and discovered that in 40 US cities, including San Francisco, Los Angeles, New York City, Washington DC and also in other nine countries were installed vulnerable controllers Sensys Networks wireless vehicle detection systems.
Figure 3 — Sensyn Architecture Slide. The company installed its systems in 40 states and its network counts more than 50, sensors operating in 10 countries, including the United Kingdom, China, Canada, Australia, and France. Vehicle detection systems are composed of magnetic sensors hidden in the roadways that collect information about the traffic flow and wirelessly transmit it, through the proprietary protocol Sensys NanoPower Protocol, to nearby access points and repeaters, which then sent the data to traffic signal controllers.
Figure 4 — Sensys sensor. Theoretically, an attacker could sniff the traffic, reverse engineer the protocol and replace information with fake data. Sensor identification information sensorid , commands, etc.
Because of this, wireless communications to and from devices can be monitored and initiated by attackers, allowing them to send arbitrary commands, data and manipulating the devices. Anyway, sensors are just a component of the overall architecture, it it necessary to submit the information in the correct way to trick control traffic light systems into thinking that the actual traffic flow is different from the real one. Another security issue noticed by the researcher Cesar Cerrudo is related to the possibility to alter the firmware running on the sensors.
The code is not not digitally signed and is not protected by any security mechanism, this circumstance led the experts to think that a threat actor could access the firmware and modify it to alter the configuration and the behavior of the devices. An attacker for example, could hack the sensor in order to provide fake data or just to transmit data on a different radio channel. In both cases, as highlighted by Cerrudo, it would be very hard to detect a potential attack and identify the compromised sensor.
The attacks explained by Cesar Cerrudo could cause serious problems to the tragic flaw, an attacker could manipulate the transition times of traffic lights creating traffic jams and other problems, and such attacks are quite impossible to discover in a short time. The Researcher Cesar Cerrudo explained that is not necessary an expensive instrumentation to hack control traffic light systems, he explained that an attacker could use a small specialized equipment to do it. The access point acquired by the researcher is compatible with all the sensors used by the Sensys to monitor the streets worldwide.
The access point intercepts data sent by sensors, for this reason he placed it in a backpack or on his car dashboard during the experiments conducted in the streets of different cities, including Seattle, New York, and Washington, DC. Figure 5 — Sensyn Access Point. Anyway, an attacker could intercept data anyway without the Sensys access point, he could simply intercept exchanged data using a wireless transceiver, but this process is more complex without the knowledge of the proprietary protocol used.
A threat actor having the knowledge of the protocol could capture the data sent by the sensors to the access points, which includes configuration information about the devices such as the unique ID of the sensors. As explained by the researcher, a sensible improvement of the overall security of networks of traffic light systems could be obtained by encrypting the communications between sensors and the access points.
As described in the study, an attacker could also intentionally modify the firmware of the sensors or their configuration data, for this reason another suggestion provided by Cerrudo is to prevent unauthorized users from accessing the firmware.
With Levitate, you can reach the ledge at the top pictured above and clamber into the pipes. Run to the end and you'll be in the room with the Rubber Duck, but it will teleport away as you approach. It'll keep teleporting down the corridor as you approach until it reaches the other end, before turning back around. Just run after it until it lets you get close enough to cleanse it, then return to Langston in the Panopticon once more.

In a paper published this month , the researchers describe how they very simply and very quickly seized control of an entire system of almost intersections in an unnamed Michigan city from a single ingress point.
The exercise was conducted on actual stoplights deployed at live intersections, "with cooperation from a road agency located in Michigan. The network is IP-based, with all the nodes intersections and management computers on a single subnet. The systems in question use a combination of 5. The paper notes that researchers could have reverse-engineered the protocol to connect but instead chose to simply use the same type of custom radio for the project as the intersections use.
We chose to circumvent this issue and use the same model radio that was deployed in the studied network for our attack. While these radios are not usually sold to the public, previous work has shown social engineering to be effective in obtaining radio hardware [ 38 ] Once the network is accessed at a single point, the attacker can send commands to any intersection on the network.
