Leave it at home and, if you need a phone, take a burner that doesn’t have your personal data and isn’t logged into any of your accounts.

[-] SnotFlickerman 48 points 1 year ago

You also have better found a way to pay for the burner in cash or with a pre-paid debit card. A lot of places in the US won't let you buy a "burner phone" without a credit/debit card that has your name attached to it.

[-] EdibleFriend@lemmy.world 11 points 1 year ago

Walmart lets you. At least as of October. The only rule was the amount of phones.

[-] delirious_owl@discuss.online 4 points 1 year ago

Wut? The US is like one of the easiest places to buy anonymous mobile phones and plans.

[-] Baku@aussie.zone 4 points 1 year ago

Seriously. In Australia, you have to "activate" your Sim card with your full name, email, bank details (depending on the carrier), and a copy of your driver's license. Hell, I bought my last phone directly from a carrier, completely outright, with cash, prepaid with no plan, and they took a photocopy of my drivers license. Buying phones elsewhere they've never done that to me, as long as it's prepaid and bought outright, but for some reason the major telcos do it for all purchases

Usually what you do in this situation is go to the tourist hot spot and find a mobile shop pretending to be a tourist without a drivers license. Usually within a few days you'll find someone who will use their info and sell you a Sim card.

[-] nossaquesapao@lemmy.eco.br 3 points 1 year ago

What about buying second hand?

[-] jjlinux@lemmy.ml 62 points 1 year ago

Leave it at home.

[-] electro1@infosec.pub 54 points 1 year ago

Just leave your phone at home, and bring a Digital camera, and few SD Cards ... Oh, wait.. < insert company name here > makes Cameras that spy on you... nevermind...

maybe we should hire a fast sketching artist to draw police brutality ... What.!... your pencil can track you now... come...ooooonnn

[-] delirious_owl@discuss.online 28 points 1 year ago

No, its better to have a smart device that syncs photos to your encrypted cloud in case you're attacked and your attacker breaks your SD card to destroy the evidence

[-] rar@discuss.online 11 points 1 year ago

Burner phone to anything that requires communication. Erase metadata of anything that will be shared and uploaded online.

[-] Pantherina@feddit.de 5 points 1 year ago

Burner phones are a strange concept. If you want to store sensitive data on it, you shouldnt use some cheap android phone or even a dumbphone without encryption support.

[-] SnotFlickerman 5 points 1 year ago

All Androids since 9 at least have been encrypted by default as long as you have a lock screen enabled. Doesn't matter if its cheap, it is there.

[-] Pantherina@feddit.de 5 points 1 year ago* (last edited 1 year ago)

All Android phones have Google malware installed by default, as system apps, which means those apps can do whatever they want.

So every piece of data you put on there is possibly tracked and collected.

Then there are 2 more problems

  • the software is proprietary and cannot be externally wiped clean
  • the software is outdated

This makes it vulnerable to Pegasus attacks and others. There are tons of secure practices to avoid getting it, like LTE-only, HTTPS only, encrypted and trustworthy DNS, sandboxed processes, blocked javascript execution from unknown websites...

But still if the phone is outdated there are unpatched and publicly known security issues. Just spamming them at all phones is likely to succeed as so many people run vulnerable versions, as vendors suck.

Then if you have pegasus, the only way for security is to reflash the A/B partitions, both. Factory reset is not secure as it will keep what is already in the system partitions.

The firmware is protected and signed by the vendors, so it is likely clean.

But Pegasus installs itself to the phone storage.

If you A cant obtain factory images or B cant flash the phone at all, you cannot wipe it clean.

So a good activism phone needs

  • trustworthy and minimal system apps / stock software
  • modern software updates
  • possible to reflash whole device externally
  • nice to have: ability to verify checksum of system partition, like GrapheneOS Attestation

This makes them poorly pretty expensive. I think a slightly outdated GrapheneOS phone is okay though.

[-] Lemongrab@lemmy.one 9 points 1 year ago

Then get a burner pixel 3a and install grapheneOS or DivestOS

[-] Pantherina@feddit.de 4 points 1 year ago

I think 3a is already too old. I think 4a is a better minimum, but this is still insecure of course.

While leaving it behind is best for privacy, the article touches on some reasons people bring them anyway

Leaving your phone behind means the data it holds and transmits will be the safest it will ever be, but it also means giving up access to important resources. It becomes much more difficult to coordinate with others, or get updates from social media. For many, phone cameras are also the only way they can document what’s happening.

If you have access to a separate phone, whether it’s a “burner” phone, an old smartphone that you can reset, or an old-fashioned camera, you could choose to bring these devices instead of your regularly-used phone. However, not everyone has access to these devices, or can afford to purchase a separate phone just for protesting.

[-] henfredemars@infosec.pub 43 points 1 year ago

Phones are tracking devices. Do not bring your phone, not even turned off because many phones emit Bluetooth beacons and other data that can be recorded and traced.

If you bring a phone, make sure that phone has no idea who you are.

[-] floofloof@lemmy.ca 24 points 1 year ago* (last edited 1 year ago)

Even if the phone doesn't know who you are, the shop that sold you the phone or the SIM, or the credit card company you paid with, can know who you are. So you'd have to use cash. Even without these, your movements can be tracked through a burner phone and informed guesses made about who you are (e.g. if the phone has been at your home or with your friends).

Turning off your phone doesn't necessarily protect you from tracking either:

https://www.androidauthority.com/android-15-powered-off-api-pixel-9-track-switched-off-3425472/

Easiest, as others say, just not to carry a phone.

[-] TheOSINTguy@sh.itjust.works 8 points 1 year ago* (last edited 1 year ago)

In some places, you cant buy a burner with cash, but you could with a gift card that was registered with cash or a prepaid debit.

I would also recommend buying a faraday bag to keep it isolated.

Edit: keep that in the faraday bag untill you need it.

[-] delirious_owl@discuss.online 16 points 1 year ago

If everyone followed this advice, we wouldn't have footage of abuse at protests..

[-] henfredemars@infosec.pub 4 points 1 year ago

Mostly true. I will not deny there are benefits to bringing your phone. They are also substantial risks. Protesting can be risky business.

[-] cm0002@lemmy.world 6 points 1 year ago

not even turned off because many phones emit Bluetooth beacons and other data that can be recorded and traced

That's a bunch of bull, off is still off unless you have a reputable link/source that says otherwise.

No need to spread misinformation or conspiracy theories.

[-] henfredemars@infosec.pub 32 points 1 year ago* (last edited 1 year ago)
[-] cm0002@lemmy.world 5 points 1 year ago

Ok I stand partially corrected, it's something that's coming but is not rolled out yet and looks like it'll need the latest phones so everything slightly older is still fine

[-] henfredemars@infosec.pub 12 points 1 year ago* (last edited 1 year ago)

It is actively rolled out right now all the way back to iPhone 11 (2019) while the device is powered off. Version 16 is current, and the power "off" tracking was backported to older devices.

Android support is spottier. We've had powered off features one OnePlus for some time, such as the ability to trigger alarms while turned off, but more advanced features like location tracking are much more recent to Android because it usually requires specific hardware support to operate while using almost no battery. Apple has the privilege of vertical integration, so they were able to update older firmware.

I think this trend is very concerning, because with no user-servicable battery, we're essentially forced into having our phones on to some degree at all times.

Never underestimate how far they will go to track your movements, habits, etc. It's not even about "the gubment spyin' on me". It's about how valuable that data is to corporate assholes who like to target you with customized advertising, and resell your data, etc. (And yes, as a side-effect, the police can also sometimes take advantage of this ubiquitous data capture).

We live in a time when even our stupid cars spy on us:

https://www.nytimes.com/2024/03/18/podcasts/the-daily/car-gm-insurance-spying.html

It's why they push the internet of shit so hard. Nobody needs a "smart fridge" but by god, they really want us all to have one.

[-] delirious_owl@discuss.online 3 points 1 year ago* (last edited 1 year ago)

Well, its about both.

The drones with IMSI catchers flying over BLM protests are not for corporate gain.

[-] NoLifeGaming@lemmy.world 26 points 1 year ago

Don't take it with you, or have a faraday bag and only take it put when you're done

[-] menas@lemmy.wtf 24 points 1 year ago

Pretty good stuff.

However I read many reactions : "don't take your phone with you" This is a common issue in a lot of activist place to don't ask ourselves why people are acting like this ? before telling them to stop. They may have good reasons, and in a case of protests, there is.

  • Filming the cops : I don't know in the US, but in a lot of countries, cops are less violent when they know someone is filming them. This may help people harmed by the police, in giving them evidence, or helping mobilization in the futur. After mass arrestation, it could be hard to know how as been arrested or not; some legal support hotline ask this kind of evidence for this reasons. Of course this some sensitive material, and need to be secured too. For example, the cops may target you if you are filming them.

  • Calling the legal support hotline : Some of them ask to be called just after arrestation or cops actions, to make a precise report. You could call them when someone you know have been attacked or kidnapped by the police.

  • Call medial support : I don't know how the emergency number is linked with the repressive force in the US, but in a lot of country, it's not. Even if it's rare, it could be a vital issue.

All this actions are important and individuals should compare the risks they take in taking them and what we lost in not acting like that. Of course this risks have to be documented; with flyers at the start of a protests for example.

I would recommend to mutualise actions to decentralize risks. Make a team with one or two people with burned phone and dedicated camera (paid by everyone); let your other phones at home. Stay (at least) by pair, and keep in eye someone with a phone.

They may be better plan of actions, but we couldn't just let down cop watch ant street medic just for the illusion of individual safety. Such thing simply do not exist

I'm waiting for the first mass protest that utilizes Lora communications

Come on noobs, get with the times!

Signal & WhatsApp are not secure enough. Meta/Facebook regularly give data & metatadata to the cops & Signal is centralized & not self-hosted by your crew so while messages are encrypted, the metadata still isn’t. If you must use Signal, I would pick Molly as an Android client since you can a) encrypt the messages under a separate password for storage on seizure & b) you can use the UnifiedPush version to make sure your notification metadata isn’t going thru Google’s Firebase servers. Protests are the ideal place for Briar as it is works via mesh net so internet & SIM cards are not required (but years ago wden I tried it, the app was a major battery drainer).

[-] toastal@lemmy.ml 13 points 1 year ago

Also worth noting that OpenStreetMaps works offline too.

[-] cyrus@sopuli.xyz 9 points 1 year ago

the metadata still isn’t.

That doesn't quite work in the case of Signal

The only data that they have, based on transparency reports and dissections of their source code, is the time you created your account and last connected to the servers.

Messages themselves are essentially only relayed, with sealed sender, and anything that would be actually useful to identify who was at a protest and who wasn't encrypted.

Things like, e.g when messages arrive at the server would have to be monitored live on compromised servers, which reasonably unless you assume* it is wiretapped already prior to a protest, isn't realistic.

*: of course, I am saying this because making an assumption and portraying it as truth (e.g assuming something is already wiretapped based on no evidence at all) is not the smartest of moves when it comes to threat modeling...especially if you wanna stay sane whilst having a threat model

You are absolutely right about metadata, but as far as protests, just having encryption is enough to prevent anyone from accessing the data. Extracting metadata from 3rd party companies or extracting a phone requires a lot more resources than cops can spare.

If your problem with signal is that it isn’t self-hosted, just self-host it? It’s all open source.

[-] toastal@lemmy.ml 5 points 1 year ago

Those components are not really meant for self-hosting, its open to be looked at. You would need to patch out the SIM requirement, point the hardcoded server/clients elsewhere, find some way to sideload modified clients to those using iOS lol, & it’s not federated so you would need a separate app for just this task. At this rate you are 100% better off using a choosing systems where server & clients are actually built with this in mind… Signal’s chat features are not novel

Anything with Bluetooth is a ID vector.

And since Apple AirTag tech is a thing there are other ID capabilities.

Maybe a Faraday bag to cut all radio.

[-] Trent@lemmy.ml 10 points 1 year ago

I wouldn't even bring my phone, or if I absolutely needed something like that, I'd buy a cheapass pre-paid burner. And keep it off until you actually need it.

[-] possiblylinux127@lemmy.zip 8 points 1 year ago
[-] amongstthetrees@lemmy.ml 6 points 1 year ago

On a secondhand or wiped burner Pixel too. The Crowbar CVE can’t be patched by an OS.
