Does this apply to iPhones? So someone could put this outside my house and listen to all my iPhone calls?

- dboreham 8y agoAny kind of phone.
- UncleEntity 8y agoThey can't listen to your calls without cracking the keys shared between the phone company and your phone...though I do remember reading a while back that "someone" managed to steal the list from sim card manufacturers on more than one occasion.

To avoid getting folks too worried about it being a widespread issue, this occurred for specifically targeted MENA-based cellular carriers, as I recall.
- dsl 8y agoThat is not true. Stingray's are cell towers and phones trust them. The device just downgrades to A5/2 (export grade) encryption, or broadcasts that it does not support encryption at all.
- kalleboo 8y agoSeems like a huge oversight to not let SIM cards disable certain types of encryption (that it knows the home network will never use). IIRC this is how downgrade attacks are prevented in EMV - the chip card will reject known-broken auth methods.
- supertrope 8y agoThe FCC takes a dim view on 911 call failures. All phones must support disabling GSM encryption as a fail safe. Never disabling encryption would be “fail secure” (like door locks that remain locked during a power outage).
- kalleboo 8y agoEmergency calls already have a bunch of exceptions that don't apply to regular traffic (e.g. you can use any network, heck you don't even need a SIM card) so allowing only those to be unencrypted shouldn't be too much of a stretch
