Some people came across some warning messages when opening LoafWallet on jailbroken iOS devices. At some point, it refers to tweak makers having the ability to access and steal the Litecoins from LoafWallet.
In a recent update, the warning is said to have come from the entitlement/signature verification, which has been disabled on jailbroken devices. This happens because iOS has a keychain that can store secret content. At the same time, it has access control and encryption. Accordingly, access control relies on entitlements, the pieces of info embedded into the code signature of the app.
The information that your iOS device has could be accessed by someone who was given the same entitlement to a particular keychain group that you have. This can occur if a malicious developer would sign an app to the keychain group that your device was signed into. This could happen to jailbroken devices, which can actually provide information about your device and its content.
In a normal iOS device, this fault wouldn’t happen because entitlements have never been patched out. Likewise, when there are malicious activities, these would be rightfully detected. Be it sideloaded from the Cydia app or otherwise, any tweak on the entitlement wouldn’t be accepted. Thereby, the entitlement would be killed upon any attempt to launch.
Such warnings would exist because jailbroken devices are prone to vulnerabilities. Therefore, you should be careful the next time you want to install apps on your jailbroken iOS handheld devices. If you haven’t experienced it yet, then you might haven’t been exposed to such vulnerabilities yet. However, it is not a guarantee that your system has not been compromised.
Thus, jailbreaking your iOS device might give you tons of features not found in normal devices. Nevertheless, you should be cautious enough not to harm your device by installing apps with malicious intent.
