This is completely wrong, and in multiple ways.
For example:
> There are various methods used to obtain the IMEI. The most common methods are to hack into the cellular company, or to eavesdrop on the cellular network.
Or on Android, go in settings, about phone, and tap MEID. There should be an equivalent on iPhone. The MEID and IMEI are not secret at all. They just identify that particular phone.
The part that one would want to clone is the subscriber part anyway, not the equipment ID.
> A GSM SIM card is copied by removing the SIM card and placing a device between the handset and the SIM card and allowing it to operate for a few minutes and extracting the Ki, or secret code.[citation needed] This is normally done with handsets that have the option of an "extended battery" by placing the normal size battery in the handset and the Ki in the now vacant extra space. This is done by allowing the device to log the interaction between the mobile telephone switching office and the handset.
The Ki is just a cryptographic key (not a physical thing as the article would imply by it needing "vacant empty space"), and is not exposed on the wire protocol between the handset and the SIM card. The handset forwards cryptographic challenges from the mobile network to the SIM card, and the SIM card answers with the correct answer to the handset, which then replies to the network.
- tuyiown 7y agoYes, I took it like it mentioned ways to clone the phone without physical access to the device
- jfim 7y agoEven then, it doesn't make sense to do that. Three letter agencies can just go ask the phone company for a wiretap. Cloning the equipment ID is also useless on its own, you'd want to clone the subscriber identification, which is the part that says to the network that you're the device for this subscriber. It's how moving a SIM card to a new phone makes the new one ring and the old phone stay silent when calling the number associated with it.
- Lammy 7y agoEquipment ID and subscriber information used to be the same thing in the far past: http://web.textfiles.com/phreak/cell.txt http://web.textfiles.com/phreak/cell.txt People cloned phones to make free calls, not receive them — like a '90s/2000s version of blueboxing: https://www.pressherald.com/2010/04/19/woman-finds-cell-phone-bill-inf-lated-by-cloning-calls_2010-04-19/ https://www.pressherald.com/2010/04/19/woman-finds-cell-phon...
- zvr 7y agoThree letter agencies can just go ask the phone company for a wiretap in their country . They are also interested in performing similar tasks elsewhere in the world ;)
- ThePowerOfFuet 7y agoThe Ki can be derived by interacting directly (electrically, not remotely) with the SIM for a few hours, at which point it's possible to clone the SIM.
