Wait until your learn what a country or local government/police can do remotely to the baseband firmware of your phone with a court order... 10-20 years ago the FBI was regularly remotely programming firmware to listen in and record cell phone microphones to capture conversations of suspects. IIRC a mafia case hinged on data gathered in this way so it is not some abstract theoretical or crackpot theory ( https://www.…

I rotate burner SIM's. I never make calls with the SIM. Instead I use jmp.chat if I need to use OTA calls or SMS. I am in airplane mode 99% of the time and use WIFI instead of cellular. I never activate cellular near my home. I am always connected to VPN so that the traffic cannot be analyzed. My phone is anonymous without any identifiers. I think all this mitigates the baseband attacks, but tell me if I am missing s…

Wrap your phone in aluminum foil when you're not using it.

I was talking to someone who was charged with a fairly minor crime, and they said the first advice their very expensive/experienced lawyer gave them is to no longer trust their phone is not recording them, as the local police (australian) use this ability quite freely.

What are the odds of seven chained VPNs all being compromised?

Doesn't matter. As long as one is compromised, you're screwed. VPNs cannot break TLS, (unless you're dealing with the intelligence apparatus of a major power, which probably can break TLS) so they cannot introspect most of the content you send and receive anyways. What they can do, however, is see the domain name of the HTTP requests you send when setting up TLS. Chaining VPNs doesn't add security by any metric.

They don't have to break TLS. They just use an exploit to get access to one of the unencrypted sides of the link.

From my experience, people who do take this type of an exaggerated approach often end up exposing themselves more in ways that they don't even realize...

How do you pay for jmp.chat? Do you trust their code to be bug-free and without possible exploits? Do they do regular security audits and code reviews? Do they have enough users and maintainers to be able to quickly detect and address security issues? Are you sure Airplane Mode turns off the baseband and cuts off all cellular communication? It doesn't, you can still emergency receive alerts in Airplane Mode. Your phone can tell exactly where you are by comparing your wifi search results + RSSIs to known public databases without even having to use GPS. How much do you trust your VPN provider to keep no logs? How do you pay for VPN?

Your location data. Tower associations can still happen with data "off", since there's plenty of "listen" components. All your home wifi connections are well Geo-located, thanks to other Android users picking up the ESSID as they walk / ride / drive past your house. Your shopping / outings? Forget it, fully known. VPNs hide the content of connections, at least from MITM / eavesdroppers, but server-side data scrapes a…

From https://grapheneos.org/faq : "Connecting to your carrier's network inherently depends on you identifying yourself to it and anyone able to obtain administrative access. Activating airplane mode will fully disable the cellular radio transmit and receive capabilities, which will prevent your phone from being reached from the cellular network and stop your carrier (and anyone impersonating them to you) from trackin…

I would never trust that. It is how thing are supposed to work, not the way they necessarily will. Just buy a phone with physical disconnect switches if it is important enough for you.

> If they were, they wouldn't have been criminals in the first place. What does intelligence have to do with whether someone is a criminal? There are dumb criminals and smart criminals; I'm not sure what the correlation here is.

I think most criminals are dumb. Quick google search shows average IQ of a criminal is 85.

Probably not directly related, but mainly due to fewer opportunities. This is one of the reasons I strongly agree with universal basic income. The capitalistic game is harder than many people are capable of playing. They shouldn't have to suffer enormously because of that, and neither should society. Otherwise, should we assert that ethics are inherently easier for some people, yet penalize all people the same regardless of their capacities?

I break into Tiffany's at midnight. Do I go for the vault? No, I go for the chandelier. It's priceless. As I'm taking it down, a woman catches me. She tells me to stop. It's her father's business. She's Tiffany. I say no. We make love all night. In the morning, the cops come and I escape in one of their uniforms. I tell her to meet me in Mexico, but I go to Canada. I don't trust her. Besides, I like the cold. Thirty…

These are emergency broadcast alerts. Different countries have different laws on these - and in some countries you might not even be able to disable them. Just because its listed under "Apps & notifications"/"Wireless emergency alerts", it doesn't mean they are "user settings". Its not necessarily the local "carrier" that turned the settings on, its more that connecting to a cell tower in a particular jurisdiction ca…

If it's not a user setting, then it shouldn't be listed with all the other user settings, and labeled as something the user has control over. At the very least, any setting that can be overridden by the carrier should have a note or warning next to it, stating that. The fact that it's so unclear leads me to wonder what other settings -- perhaps some related to my security or privacy -- the carrier can modify without…

Hide number setting is something telcos can change remotely, at least its common.

Are you saying that a phone manufactured in 2022 can have its firmware remotely changed to record microphones? Specifically can your whatsapp/signal audio calls be recorded by FBI remotely in this manner?

> Are you saying that a phone manufactured in 2022 can have its firmware remotely changed to record microphones? Yes, court records show the FBI has and continues to explicitly do this. Leaks from folks like Snowden show the NSA/CIA have done this too. > Specifically can your whatsapp/signal audio calls be recorded by FBI remotely in this manner? The baseband firmware is at a level 'below' the operating system of the…

I am not at all familiar with the hardware design of phones, so I want to be very clear in my understanding.

Are you saying that the electrical signals from the microphone and to the speakers pass through the baseband chip before/after going to the main chip on the phone? Or that the baseband chip has separate access to the microphone and speakers?
