  • Open Terminal on your Mac.
  • Type the following command to disable the Trust This Computer prompt:sudo killall -STOP -c usbd

    There Are Lots Of Companies Abusing Certificates

    Facebook isn’t the only culprit abusing certificate licenses. For another big name example, Google was doing the exact same thing as Facebook, using a root CA certificate to grab any data going to and from the device for deep packet inspection. And while “trusted” root certificates are the biggest things to worry about, there are regular certificates as well as configuration profiles with or without them.

    Anonymous program participants were using the Developer Enterprise Program to distribute porn and gambling apps, and shady developers took advantage to hand out cheating-based versions of popular apps such as Pokémon Go and Angry Birds, as well as pirated versions of paid apps like Spotify and Minecraft.

    Unapproved app stores such as TutuApp, Panda Helper, AppValley, and TweakBox, as well as beta-testing platforms BetaBound, uTest, and Applause , all require a profile installation, usually with a certificate . The same goes for the apps they distribute, as well as solo apps found online. These profiles are easily installed just by tapping on a link in Safari.

    The Security Risk Of Profiles


    Profiles are configuration files which make it easy to deploy custom settings to an iPhone or iPad. These profiles can contain information needed to access a network or configure email accounts.

    Corporations and universities use profiles to easily deploy the settings needed to get a new device onto their network. Consumer-facing services like Xfinity Wifi and Manhattans LinkNYC use profiles to allow users to get on their public wifi.

    But many users may not realize how powerful profiles can be. Many profiles, such as this one used by Comcasts Xfinity Wifi, contain root certificates which can be used to establish secure connections.

    Trusting a malicious root is one of those nuclear-level game over scenarios. In fact, Chromium acknowledges that if an attacker can install a root onto your device, there is nothing the browser can do to protect you.

    On Windows and OSX, that is a reasonable. Trusting a root on Windows, for instance, takes quite a few steps including downloading the root, opening the file on your computer, and then going through an import wizard.

    On iOS, it is a different story. In Safari, just clicking a button on a webpage can prompt a system dialog to install a custom profile which can include root certificates for your device to trust. While this still requires explicit user action, the simplicity of iOS makes it much easier for a user to naively follow this process thinking its the normal or proper thing to do.

    Five Tips For Using Self Signed Ssl Certificates With Ios

    December 12, 2013 inHttpWatch , iOS , SSL

    SSL certificates are relatively cheap to purchase, but sometimes it would be easier if you could create your own. You might need to setup SSL on development and test servers that have different host names or on systems that will only ever be accessed on your local network.

    Self-signed SSL certificates allow you to quickly create certificates for free, without having to pay a Certificate Authority or comply with any auditing requirements.

    The downside of using self-signed certificates is that browsers will not automatically trust sites that use them. In Mobile Safari you would see an error like this:
