Inside every modern smartphone there is a secret second computer — the baseband processor (cellular modem) — that runs its own independent operating system, has its own RAM and storage, and never fully turns off. It keeps registering with cell towers, accepts silent carrier updates, and can be exploited without the main OS ever knowing.
In this video we expose: • How your phone actually contains two completely separate computers • Why the modem stays awake for E911 emergency calls (and what else it does in the background) • How attackers can hijack your location, calls, and texts by exploiting only the radio chip • Who really controls the modem (Qualcomm, MediaTek, Samsung + your carrier) • Why Airplane Mode, removing the SIM, and even powering down don’t fully protect you From journalists in hostile regions to everyday privacy-conscious users — this hidden computer affects everyone.
Why no mention of Apple? This is second year of making their own modem on one of the most popular phones.
Should be covered for complete picture. But this doesn’t protect you as a consumer. Apple still has to let carriers execute code on phones. From perspective of attacker, targeting apple hw is best investment of time and effort, biggest market per exploit found.
The movies were right! We should all smash our phones! Who’s with me? On 3, 2,
The real reason they did away with removable batteries.
The sneaky fuckers.
Always keep an empty chip bag with you.
like food chips?
They can act like a cheap faraday bag in a pinch
THANK YOU!
Older Faiphone models let you remove the battery in seconds, for newer ones you need a screwdriver.
Up until the FP5. The FP6 needs a torx screwdriver to remove the battery (which is still better that 99% of smartphones which are simply glued).
Why is the fairphone moving that way? We have torx, it’s not a blocker for us, but the rarer your screws’ bitting is, the harder time people will have interacting with the hardware they bought…
A good faraday bag works as well as taking the battery out used to.
But, of course, that only works until you take it out of the bag. But, taking the battery out only works till you put the battery back in.
The only way to stop corporations from doing evil is to regulate them, and then enforce the regulation. Which is why they all lobby against regulation and bribe politicians, and judges.
They’ve also spent billions over the years fooling poors into believing that deregulation was good for them, when all it does is tighten the grip of the filthy rich.
A “good” faraday bag is hard to find, it takes more than some aluminized mylar to stop a cell signal.
There is a small typo (a dropped dot st the end of a sentence) that significantly changes the last paragraph:
• Why Airplane Mode, removing the SIM, and even powering down don’t fully protect you From journalists in hostile regions to everyday privacy-conscious users — this hidden computer affects everyone.
So it reads to me like airplane mode doesn’t fully protect me from journalists in hostile regions :)
It does, for Graphene OS.
Sames as PC/ Laptop Intel Management Engine, runs its own microcode on the chip. Can access keyboard logging, network, and other aspects. There was a 2017 exploit where attackers could login with a null password and compromise your PC.
I thought this was known. It’s one reason your phone battery dies when turned off. Because that chip never actually turns off.
