Your WhatsApp Private Chats Might Not Be Safe, Lawsuit Suggests

A new lawsuit is raising questions about the privacy of WhatsApp messages. The lawsuit claims that Meta, the company behind WhatsApp, can access users’ private chats despite the promise of end-to-end encryption. It is filed in the US District Court in San Francisco by a group of plaintiffs from Australia, Brazil, India, Mexico, and South Africa.

Lawsuit challenges WhatsApp’s end-to-end encryption

For the uninitiated, WhatsApp offers privacy for private chats through end-to-end encryption. This means only the sender and the recipient can read messages. The company says, “No one outside of the chat, not even WhatsApp, can read, listen to, or share them.” However, the plaintiffs allege that Meta’s privacy claims are false.

According to the lawsuit, WhatsApp and Meta “store, analyze, and can access virtually all of WhatsApp users’ purportedly ‘private’ communications.” The lawsuit mentions that courageous whistleblowers helped to bring this information to light. However, a Meta spokesperson called the claims “frivolous,” and said the company “will pursue sanctions against plaintiffs’ counsel.” They also said WhatsApp messages have been end-to-end encrypted using the Signal protocol for a decade.

As the whistleblowers noted, the process for Meta workers to obtain access to private WhatsApp chats is quite simple. They just need to send a request through the internal system to a Meta engineer with an explanation. The engineering team then grants access (often without any scrutiny). As such, the worker can pull up any WhatsApp user’s messages based on the user’s User ID. The messages appear in real-time, and the worker has unlimited access. Moreover, they can see messages from the time users first activated their accounts (including deleted chats).

The lawsuit gained a lot of public attention, including tech figures like Elon Musk. He said WhatsApp is not secure and suggested using X Chat instead. We should learn more about the case in the coming months as it moves through the courts.
