Lots in the news about cracking iPhones. Here’s some net net advice
- Let us all hope that iOS 10 not only signs updates with their key but also encrypts with the user passcode.
-
For the current iPhone the easy thing to do is to use TouchID and then bump up the passcode from 4 digits to custom alphanumeric. Go to the same length as your computer codes. Hopefully 12 char actors random or 7 random words.
-
Disable iCloud backup. That isn’t secure. Most of the time you don’t need that anyway. If u do want to backup revert to iTunes backup and use another strong key. I don’t know why people need backup anymore. I suppose for you iMessages?
Then normal security thoughts
-
1password continues as recommended password manager. Use a strong key and write it down. Because they cat recover it. Also if u don’t use windows or Linus sharing then u can use opvault file format and not the less secure agile format. I’m probably going to move my vaults into iCloud as a result and leave the shared ones on Dropbox.
-
Get a vpn. Private internet access has been working well across windows, iOS, Mac and Linux. It is nice to have end to end vpn.
-
For sensitive stuff us tor on windows and Mac. U can’t use for iOS but they do have a proxy into tor.
-
Use signal or wickr for really sensitive communications. iMessage isn’t too bad in a pinch although apple has those keys.
