iOS Keychain Dumper
Since the Keychain stores sensitive information, attackers are naturally interested in accessing its contents. We can use the iOS Keychain Dumper tool, to dump the contents of the iOS Keychain on jailbroken devices.
To use the Dumper tool, simply download the keychain_dumper executable and copy it on a jailbroken iOS device. Running it without any options will only dump “Generic” and “Internet” password items. The option “-a” will dump all Keychain items.
