Why NowSecure Workstation users should update iOS testing devices with caution because a jailbreak might not yet be available
Why users should keep devices running major iOS versions that are not yet Jailbroken on reserve in anticipation of NowSecure Workstation support for those versions.
To account for all possible scenarios, mobile apps should undergo security testing in a worst-case environment such as on a Jailbroken device. For this reason, NowSecure Workstation tests iOS apps on a Jailbroken version of the iOS operating system.
A jailbreak method for a new version of iOS is not immediately available upon Apple’s release of an iOS update. In addition, soon after a jailbreak is available, Apple will release a new version of iOS that patches the jailbreak method.
As soon as a jailbreak method for a newer version of iOS is available to us, our research and development team begins updating NowSecure Workstation and the agent to support testing of apps on that Jailbroken version of iOS. Until that NowSecure Workstation update is released, however, a device running a non-Jailbroken version of iOS will not function with NowSecure Workstation.
Therefore, we recommend that whenever Apple releases a new major version of iOS (e.g., iOS 8, 9, 10, etc.), NowSecure Workstation users do the following:
Update another device not currently used for testing to the new major iOS version
Keep that device on reserve
Refrain from performing any further updates on that device
Do not update your primary testing device as they are usable for Jailbroken testing in Workstation (this includes iOS 11.0 - 12.1.1 or even 10.x devices that you use regularly). We support up to iOS 12.1.1. Please only update spares or Jailed devices to iOS 12.1.1 in anticipation of the upcoming jailbreak.
This will ensure that as soon as NowSecure Workstation supports a new major version of iOS, you have a device on hand you can use to test apps on that Jailbroken version of iOS.
We expect to support iOS 12.1.1 jailbreak in the near future.
Put the device in DFU mode for device restore.
Restore the new iOS version onto the device.
