Background Passive FTP with No GUI Control Survives Apple Store DFU

    It's pretty easy to go online and understand what the "FTPPassive" key is (and why it's enabled by default). The firewall settings thing is a UI bug, if that. Those other toggles don't take effect when blocking all incoming connections is active. As such, it doesn't matter what the value for the other toggles is, so it resets them to the default (true). Perhaps a sharp point if you toggle firewall often, but not an outright security issue. My laptop has that systemuiserver preference setting there as well.

    I think this person is a bit paranoid and reading a bit too much into things judging from their timeline.

      The firewall toggles flipping on and off immediately following a device firmware reset at the Apple Store shouldn’t happen.

        I'm not sure what you're saying here. I'm mainly pointing out that the UI toggles being counterintuitive doesn't change the semantics -- blocking all incoming connections blocks built-in and signed software from receiving connections too.
