Is every buffer overflow important enough to need detailed discussion and commentary?
- 0x0 9y agoI think these latest sets of wifi flaws are interesting if it turns out they are exploitable by merely being in radio range of an attacker even without joining a malicious network or requiring user interaction. That could quickly become a fast and wormable attack. You could probably flood across an entire city jumping from chip to chip in no time. Especially now that iOS 11's wifi-off button in the control center no longer actually disables the radio, but merely disassociates from the current access point.
- ronnier 9y ago> Especially now that iOS 11's wifi-off button in the control center no longer actually disables the radio I still can’t belive this decision. I keep my Bluetooth and Wi-Fi off as much as possible and it’s now difficult to to as a result of this change is ios11. Really bothers me.
- sigjuice 9y agoApple's explanation of why they did this. https://support.apple.com/en-us/HT208086 https://support.apple.com/en-us/HT208086
- macintux 9y agoThanks, their description is interesting. It’s not quite as bad as I thought.
- Razengan 9y agoJust go into Settings and disable it as usual.
- MBCook 9y agoI really don’t understand why people keep those two off. If you’re not using them they use very little battery at this point; it’s not like it was 10 years ago. Since Apple keeps detailed usage statistics (from the people who opt in) my guess is they know how common such a behavior is and it’s obviously low enough they don’t think this change is a problem. I agree with some of the other comments I’ve seen that this probably accomplishes what the user is trying to do (ignoring a Wi-Fi network that’s temporarily behaving poorly) and possibly protecting them (forgetting to turn it back on it running up a huge cell bill). I know I’ve heard complaints from people who accidentally did that a number of times.
- nickhalfasleep 9y agoFaraday cage cases are going to be popular next season.
- kevinchen 9y agoThis is a bad take. If your threat model has you concerned about people who follow you around and exploit your Wi-Fi firmware, you probably shouldn't ever have Wi-Fi on -- or maybe you shouldn't be using a smartphone. For everyone else, the new behavior allows users to disconnect from bad Wi-Fi in Control Center while improving their battery life in case they forget to turn Wi-Fi back on.
- lathiat 9y agoI can.. it makes those buttons much more useful for the common case. e.g. this wifi network isn't working, disconnect.. and not forget to reconnect later. I did that often. And also being hassled about location services not working, etc. You can still actually disable both through the settings up, just not with the quick access.
- dpkonofa 9y agoIs it really that difficult to use? C'mon... Just force touch it instead of regular touching and you get the same control as before.
- 0x0 9y agoLots of devices don't support force touch, for example all iPads, and iPhone 5s, 6 and 6plus.
- eklavya 9y agoAm I missing something? Force touch doesn't do anything except show a bigger control with all the radio settings. There is no option to disable wifi, you still have to go to the settings.
- flukus 9y agoDoes not having to join a network make a big difference for a worm considering the amount of wifi networks we share with large numbers of other people?
- bmon 9y agoI'd say so. Imagine a worm which could spread itself to any phone within WiFi signal range. I'd guess at a worm like that covering a whole city at a really rapid pace. If you're stuck with infecting networks then the main transmission vectors would be offices, homes and cafes/restaurants etc. I think it would be much slower and much less far reaching.
