Meta is facing a lawsuit in the United States over claims that WhatsApp misled users about the scope of its end to end encryption.
A lawsuit filed in the US District Court in San Francisco accuses Meta of misleading users about WhatsApp’s privacy and encryption features. The plaintiffs allege that public assurances, including in app messages stating that only chat participants can read messages, do not accurately reflect how user data is handled.
According to Bloomberg, the case includes plaintiffs from Australia, Brazil, India, Mexico and South Africa. The complaint claims that Meta and WhatsApp store and analyse the substance of communications and that company employees can access them. It also refers to unnamed whistleblowers, though no individuals are publicly identified.
Meta has rejected the allegations and described the lawsuit as “frivolous.” A company spokesperson said WhatsApp has used end to end encryption based on the Signal protocol for the past decade and added that Meta plans to seek sanctions against the plaintiffs’ legal team.
The lawsuit has reignited debate around the limits of encryption claims made by messaging platforms. While end to end encryption is designed to prevent platforms from reading message contents, concerns remain around backups, account takeovers and spyware, issues that have been raised by researchers and regulators in past examinations of messaging services.
