> Turning off the phone isn't a solution though. Since most phones no longer have power-off, a faraday bag is needed to block all RF (cellular, wifi, bluetooth) radios on the phone from communicating with nearby radios. > The concern with the attack is that someone is snooping on my connection while I use it. If I can't use my phone confidently knowing no one is watching, then my only other option would be not to trust the phone at all. This is sadly the case today. It will only change with greater participation of civil society in technology standard-setting, open-source "cyber" defense and security research. In addition to reducing usage of untrustworthy phones and radio bands, reduce funding of untrustworthy telcos by subscribing via lower-cost prepaid MVNOs.
