If hackers can read messages before or after they’re sent, it doesn’t matter if they were encrypted in between. Spyware works around encryption instead of trying to break it. Since this spied on users’ screens instead of intercepting data, it let hackers view messages before they were encrypted or after they were unencrypted. Hackers infiltrated WhatsApp in 2019 and installed spyware on users’ devices. That doesn’t mean encrypted messages are hack-proof. If a hacker or other third party intercepted a message, they couldn’t read it without the encryption key. Since the recipient is the only one with that key, they’re the only one who can read the data. That’s a lot of personal information going to other services for an app built on the guise of privacy.Įnd-to-end encryption works by scrambling a sender’s data and giving the key to unscramble it to the recipient. That could include information about users’ online behavior, location, purchases, and some identifiers like phone numbers. WhatsApp isn’t sharing messages with the rest of the Facebook network, but it can share user data. For example, the WhatsApp controversy is about data sharing and monetization, not encryption. Encryption isn’t the only security concern with an app like this, either.

Users have to opt for it intentionally, and they may not realize this. In many apps, end-to-end encryption is an optional feature.

Just because a service offers encryption doesn’t necessarily mean it’s secure, though. Unlike many messenger services and social media platforms, these apps encrypt users’ messages, so any data intercepted by third parties is unreadable. The safety appeal of encrypted messaging apps is in the name. Why May Encrypted Messenger Apps Be Unsecure?
