Interesting... Nice that IOS gives you a warning. I wonder if Android does the same?

- tmosleyIII 12y agoThat doesn't actually happen
- chmars 12y agoIt's called 'Ciphering Indication Feature' – and can be suppressed on the network side … so you can assume that an IMSI catcher ('Stingray') will not let your mobile know that it is using no or weak encryption.
- BuildTheRobots 12y agoIt's actually a bit set on the SIM card, nothing to do with the network. Check out GSM 11.11, 10.3.18
- chmars 12y agoThanks, you are of course right. I should have written network operator. The operator can turn on/off OFM on the SIM.
- BuildTheRobots 12y agoTechnically yes, but if you're talking about a stingray then I don't think they're going to have the ability to alter your sim card without authenticating with it; which is a lot harder than just using a null cipher over the air.
