Remember that episode of Leverage (season 5, episode 3),where Alec uses Marvin to wirelessly change all the street lights green so they can catch up to an SUV? And you scoffed and said “that’s so not real!”… well actually they got it right. A new study out of the University of Michigan (PDF warning), shows just how easy it is to make your morning commute green lights all the way.
The study points out that a large portion of traffic lights in the United States communicate with each other wirelessly over the 900Mhz and 5.8Ghz ISM band with absolutely no encryption. In order to connect to the 5.8Ghz traffic signals, you simply need the SSID (which is set to broadcast) and the proper protocol. In the study the researchers used a wireless card that is not available to the public, but they do point out that with a bit of social engineering you could probably get one. Another route is the HackRF SDR, which could be used to both sniff and transmit the required protocol. Once connected to the network you will need the default username and password, which can be found on the traffic light manufacturer’s website. To gain access to the 900Mhz networks you need all of the above and a 16-bit slave ID. This can be brute forced, and as the study shows, no ID was greater than 100. Now you have full access, not to just one traffic signal, but EVERY signal connected to the network.
Thirteen years after the 9/11, 28 pages of the House-Senate report on the tragedy remain sealed under lock and key. Former Sen. Bob Graham, who was chairman of the Intelligence Committee, says the material was classified to “cover up Saudi activity in 9/11.”
Recently Ron Paul spoke with his friend Congressman Walter Jones who has read the report. Although prohibited by law from revealing what he has read, Jones says there is nothing in the report that compromises national security. Now Jones is battling to have the material declassified.
On The Weekly Podcast Charles and Ron talk about unsealing the secret 9/11 records.
"It’s politically very risky to talk about, because the left and the government defenders are really, really quick to discredit anybody who raises any question whatsoever. They paint you, and they say ‘oh you question this, that means you’re a truther.’ I was always amazed, if you question and you want the truth, how they took a word like ‘truther’ and turned it into a terrible, terrible word."
– and why is the US government keeping the evidence a secret?
Some thirteen years after the event, the shadow of the 9/11 terrorist attacks on the World Trade Center in Manhattan and the Pentagon still darkens our world. The legacy of that terrible day has impacted not only our foreign policy, bequeathing to a new generation an apparently endless “war on terrorism,” it also has led directly to what is arguably the most massive assault on our civil liberties since the Alien and Sedition Acts. Getting all the information about what happened that day – and why it happened – is key to understanding the course we have taken since.
If you actually take the time to read the report, all goes along swimmingly (except for occasional redactions) until you get to p. 369, whereupon the text is blacked out for the next twenty-eight pages.
He makes the point (quoting slide 16) that the Free Software community is winning a war that is becoming increasingly pointless: yes, users have 100% Free Software thin client at their fingertips [or are really a few steps from there]. But all their relevant computations happen elsewhere, on remote systems they do not control, in the Cloud.
That give-up on control of computing is a huge and important problem, and probably the largest challenge for everybody caring about freedom, free speech, or privacy today. Stefano rightfully points out that we must do something about it. The big question is: how can we, as a community, address it?
