The right to assemble and protest is enshrined in American law, but it can still be dangerous to hit the streets to make your voice heard. Your devices are a treasure trove of information about you, and you may not always know who's collecting that data. Take a few minutes before you go to assess your digital and physical safety. Even if you have nothing to hide, you don't want to accidentally give law enforcement officials any information you didn't intend to share. Follow these tips to lock down your phone before a protest or other peaceful assembly.

    Pretty easy to take video on an old phone without a SIM, or with a cheapo burner sim.

    Are there "burner sims" you can get nowadays that don't require online activation (i.e. they can easily trace the sim back to you)?

    This might be relevant for following ICE around or direct action, but at this point there's almost zero personal risk from attending something like a rally or a march.

    My relatives and even friends my age are afraid to go to protests. They read stuff like this, and it acts as demobilization messaging. In my experience, once you get them to go once they're no longer afraid to engage, but there's an initial fear and anticipatory obedience that has to be overcome.

    inb4 protests do nothing: getting people to stick their toe in the water helps build commitment that will one day be necessary to gain critical mass for more organized disobedience.

    I go to protests without my phone, and I'm afraid every time.

    I get that nothing is likely to happen to me, but it could. I get that this is am irrational fear. But idk strategically what to do.

    No. If the data exists at any point, then a future threat will be able to exploit it, so full on nazi style fascism might not be here yet, but when it is, you'll be in danger. Data can sleep forever before it becomes a threat.

    IMO just having your personal device on you in the presence of a protest puts you in danger. They have ample tools to track cellular devices that basically cannot be guarded against without disabling the function altogether, such as with a Faraday bag. They will catch and log that you were at a protest, and use that against you later.

    Don't bring your phone period. Any and all devices can be broken into by law enforcement. Buy a burner with cash if you need some kind of communication.

    Its not the device cracking that's the problem; its the "your device was identified at the protest we have labeled a riot and has been tracked to your home, which we will now raid in the middle of the night".

    TL:DR, if you're at a protest and your signal drops to 2G, your device is being monitored and tracked. Whether or not anyone acts on that data is a whole other thing.

    Yep, ding ding ding, buy a burner phone, with cash, from a store that doesn't have many or very good cameras.

    Bringing your real main phone is you thinking you know more about cybersecurity and surveillance than Palantir, than all the cybersec and intel firms the US Mil and Police departments have been partnering with with over a decade now.

    Just don't bring it. Bring a digital pocket camera instead to document stuff.

    Nowadays, you can't use a mobile phone without signing in to some Google service or Apple. It's mandatory. Giving them access to every data you own.

    That and cell towers….

    But a cheap burner. Don’t activate it. Keep it in a faraday pouch. In an emergency remove from faraday pouch and call 911. You can do that on phones you don’t activate.

    But everything else, like you said, document with a digital camera.

    Yup. It’s a bit of a question of how paranoid are you/you feel you need to be but it may be worth keeping in mind that the baseband modem of any phone is proprietary and runs its own unaudited software the end user has no control over or insight into.

    1. Get a cheap mobile specifically for protests, especially using it for pictures and video.
    2. Set it up to livestream everything, so that any video evidence gained can't be taken away.
    3. Get a faraday bag for when you need to put that mobile away and not be tracked.

    Maybe I'm missing something though?

    I got a body cam for about $50 amazon dot com/dp/B0BHZ4PRRG, currently unavailable. Makes a great dashcam too. When the usb charging cable is plugged in it turns on when you start your car and turns off when you turn off your car.

    The only thing you're missing is to put a piece of white tape on the sole of your shoe. When you are lying on the ground It's a cop signal that you are an undercover agent.

    Going to a protest? Don’t bring your phone without doing this first

    I’m skeptical of bringing your phone at all, either in airplane mode or off, because modern phones still broadcast location when it’s ‘dead’ in order for you to find it. But I don’t know enough about that to say for sure

  • source
  • hideshow 1 child comment
  • [–] 10 points 10 months ago

    Off should be off. Airplane mode often leaves WiFi and Bluetooth on because airplanes allow them. And GPS doesn't transmit anything, but if it's enabled it's still recording your location.

    Shitty article. Doesnt even contain the words SIM card or IMEI so it has no business advising people on whats safe to bring to a protest. There is no such thing as cop-proofing a mobile phone unless all wireless modules have been removed. The cops can and do track peoples cell tower signal derived locations and they can log active Wifi/Bluetooth MAC addresses in their vicinity.

    As others have said, just dont bring it if you are scared. Consider just using a bodycam or gopro style camera.

    Modern phones rotate random MAC addresses. For WiFi, capturing SSID probes can be enough to track somebody though (some phones also have some mitigation for that too, like not probing for an SSID after it hasn't been seen for some amount of time). Even when turned off, many phones, including iPhones, turn into BLE beacons similar to AirTags, which can be used to track you.

    almost worthless. I just learned that the android 13 xiaomi phone of a family member broadcasts some of the wifi AP names it knows when scanning for available networks! constantly! why the fuck it does I don't know because neither are hidden networks that would need this, and there's no setting for it

    Are those networks marked as hidden SSID networks? Hidden networks require the client STA to broadcast them to find them.

    they aren't. one of them is an AP from another phone, so I believe that one couldn't even be configured as hidden by accident, because the phone does not offer it. another is one I sometimes use, and it's not hidden either.

    This is slightly false in an alarmist fashion. At least in the US, the police are not actively tracking anything without a subpoena to the cellular provider of the phone in question. They can look at the location data after the fact, using a court ordered subpoena. They can also use live location data in an emergency situation,also using a court ordered subpoena.

    Cellular data from cell towers on cell networks are private property of the cellular provider companies. That's not to say you are private while on them. Just that the police are not actively tracking your location through them without great effort for each individual they wish to track.

    Commercial location data, in this case acquired from hundreds of millions of phones via a company called Penlink, can be queried without a warrant, according to an internal ICE legal analysis shared with 404 Media.

    I thought this was using SDKs embedded in apps and advertising platforms. This is a different threat model. You need to block ads and prefer using websites instead of apps which have more access to device info like the advertising ID.

    If you've got an Android, go to Settings, search for ads, and find the advertising ID and delete the ID. It's a stable identifier that can be used to identify your phone.

    Switch to more private browsers like Firefox for Mobile and install uBlock Origin.

    EDIT: I'm not saying this will protect you against IMSI catchers or tower based drag nets. In addition to not bringing your phone, when you do go home you need an entirely different set of tools to protect yourself.

    Cripes all of that and not even, "Buy a burner SIM card", "Use a VPN at all time if you have to use data", "For the love of god don't use biometrics as authorization, use a alphanumeric password to unlock", "Use the damn encryption solution provided by your phone's OS".

    A VPN does not stop location data for your physical device when looking at cellular data from the carrier. Your location can and is always triangulated using cell towers. VPNs only ever protect your IP address from being geolocated and encrypting the data downloaded and uploaded while connected. Bit streams are still sent and received from a physical place in the world before the VPN hides your traffic and that is recorded by the cell provider.

    Shut off and leave your phone at home, buy a pay-as-you-go to bring with you for emergency contact /coordination

    Leave the pay-as-you-go phone powered off too, and only power it up if you actually have to use it. If you have to use it once, you need to get a replacement for a future event.

    I'm thinking perhaps something like Meshtastic transmitters and receivers should be used for coordination instead.

    I believe there are Bluetooth network protocols that mesh that would work for messaging and not require cell service. It would be smart to organize using something like that and just use any cell phone without cell service turned on. That still gives you the ability to call 911 in case of emergencies as well.

    Does that matter? If it's a device that you bought used just for this? There is no name attached to that device at that point. Buy it used on Craigslist, use it for the event, throw it away. It can be any cheap, crappy phone.

    Cell service is always turned on on a phone, even with no SIM card and the phone in airplane mode, and for most phones, even when the phone is “off”. They still ping the local towers semi regularly; they just don’t ramp up transmission power ir try to establish a full connection.
