Defense contractor Leonardo is promoting a new technology called SignalTrace that will package plate cameras with sensors that can scrape unique identifiers tied to your smart devices and make that data available to law enforcement.

Police, border security, and other government agencies already comprise Leonardo’s customer base, and with this technology, those clients seek to correlate footage from these cameras to phones, tablets, wearables, AirTags, and, naturally, the electronics inside cars themselves.

If SignalTrace can pick up your Bluetooth headphones, you can be sure it’ll also be looking out for your vehicle’s 5G hotspot, infotainment system, and even its tire pressure monitoring sensors. The company includes pet microchips as a potential entry point to tracking.

    How many criminals are taking along their microchipped pets to and from their crimes?

    Rhetorical question I know. They simply do not want to allow dissidents and undesirables the freedom of movement.

    Also, if you contribute to a project like this, you are a traitor and should be treated as such.

      How are they going to read pet microchips? They’re not broadcasting a signal constantly.

        They’re not. Pet RFID chips are low frequency and have a read range of a few inches at most. By the time you pump enough energy in to get a signal a foot away, you’ve probably microwaved the pet and blown out the chip antenna.

        I think they bounce rf waves off of them. Same as with money, larger bills have a magnetic strip, they can bounce rf waves off of them and see how much cash is out there if not shielded.

        I, like most people, didn’t read the article. However, a lot of people use tracking tags on their pets collar so they can actually be tracked if they get out. I’m guessing that is what these cameras will be picking up.

      Ya know, thats a good idea. I would make the time frame shorter depending on what the range of the transmitter is. If you switch while in range of the camera would it pick you up as two vehicles?

      There was some politician talking about how Section 702 is expiring on Pod Save America and he goes on explaining why it’s so great and needed and then one of his selling points is that there is a carve out for politicians and I couldn’t be more enraged when I heard that. Like I get the point he is making, but if politicians are above the law why would they care about the laws they are writing?

      Or motivate them to tactically acquire new hardware.

          How powerful do we need to get for that. It’d be a clean way to work on the issue. You’ll need to be in line of sight though i imagine.

            We got into this in detail on other social media. Some camera types are more susceptible, but the more powerful lasers are dangerous as shit , that could take out any camera. You need eye protection, and welding goggles might not do it because it’s different wavelengths. I’m not a technical guy so I can’t say precisely.

            But the regular laser pointers can take out some cameras.

    … pet microchips are passive LF RFID tags, they have a readable range of maybe 15cm? Unless they’ve figured out some way to power them at distance (or they’re sticking UHF tags in your dogs, which they arent) without frying the camera and giving everyone cancer, they’re inert. What weird marketing hype.

        For unimplanted tags of unspecified size sure it’s technically possible to do, but I’ll let the article summarize why this is blatant marketing hype:

        The ideal lab setup often fails miserably once you mount the reader near a gate or machine frame.

        It’s worth saying: 1 meter is an ambitious goal for 125kHz. LF systems are intentionally short-range to prevent cross-talk. If you truly need 1-meter coverage, sometimes the real solution isn’t to push more current — it’s to rethink geometry, use multi-coil zones, or explore hybrid systems (LF for identity, HF/UHF for distance).

        and then mention that the interference from the dermis vastly reduces the useful range of the tags, and that the article doesn’t actually specify what type of tag they’re designing for (or if it’s using a set orientation…).

      Nah, too easy to filter. Make them clone MACs they’ve seen, and simulate trips around the city.

          Small single board computer with a solar battery could spam fake bluetooth MACs all day and night. You would need additional hardware to fake the 4G signals (and this would be illegal) or things in the unlicensed bands like tire pressure monitor sensors.

          Your setup would cost about as much as theirs and they have infinity money, so absent some rich sponsor you’d be limited to screwing with a few nodes. A more effective use of battery power would be an angle grinder (this would also be illegal).

      Ramp the signal up and down, add some doppler shift so it makes it think the signal is in motion. They would need multiple antennas to filter that out

      Despite doing an awful lot with ESP32s, Home assistant, and a bunch of LoRa stuff, I know very little about BLE. Would it be possible for folks to voluntarily add their MAC to a data base on gitlab, and have a ESP32 program that:

      1. Spammed out whatever the max reasonable number of random entries from that database is
      2. Updated it every-time it was on a specified WiFi So that every time I drove by one of these, not only do I look like a spacehulk of TPS, headphones, cars and cellphones, but I’m specifically helping someone appear somewhere not their location as well?

      Thinking in terms of database management systems I would think these systems collect enough unique info that they probably can use ‘composite-keys’ to sort through collected content. If thats the case then they can probably filter out all of those fake MAC addresses with relative ease, but I like where your head is at.

    a couple years go by and they don’t know how to track people regularly anymore.

    so if we bypass these sensors and algorithms, we become invisible in plain sight

    Could one build a device that could overload these with fake data?

    Or should we just use cordless angle grinders?
