End-to-end encryption is the system that guarantees privacy in most messaging applications. However, there are exceptions that violate user data, and iPhones and other Apple devices appear to be the most affected.
While applications like WhatsApp Telegram They also face the same dilemma, the extreme synchronization and backups that allow a user to read the same messages on all their Apple devices in real time ends up being a double-edged sword.
“The problem is backups in the cloud,” explains Zak Doffman in his article. “With WhatsApp, users can enable or disable a backup in the cloud to restore their chat histories if they lose or change their phones,” he slides to later explain the difference with Apple’s messaging.
“iMessage not only gives users the same view everywhere, it does so with the full protection of end-to-end encryption. Even if iCloud is being used, there is still full encryption of your messaging to protect your content. But there is a serious problem, “he warns.
“If you enable generic iCloud backup on your devices, Apple will store a copy of your iMessage end-to-end encryption key within your backup. It’s like locking your front door but leaving a key hanging. Visibly from a hook inside, only in emergencies. Useless, “he warns.
How to protect yourself?
The solution is to disable the generic iCloud backup. This way Apple will set up a new iMessage end-to-end encryption key and you won’t have a copy. “A new key is generated on your device to protect future messages and Apple does not store them,” the security specialist adds.
The only problem with disabling generic iCloud backup will be if you lose your phone, as you will lose the history of all your messages. Doffman believes that it is the price that must be paid to gain security.
