Researchers at Redact have uncovered hidden instructions in the source code of WhatsApp help pages that directed the company's AI-powered support chatbot to avoid recommending users contact data protection regulators or reference key privacy laws.
The instructions appeared in the publicly accessible code of the help section. While ordinary users saw only standard support text, the chatbot received additional internal guidance specifying topics it should not discuss. Redact examined 545 help pages and found 102 concealed blocks on 80 of them.
One directive instructed the bot not to advise users who had lost access to their phone number and could not delete their account to contact supervisory authorities. This guidance contradicted WhatsApp's own European privacy policy, which explicitly allows users to file complaints with regulators.
Additional instructions prohibited the chatbot from discussing GDPR, LGPD, or CCPA once a user mentioned legal action or an attorney, even if the user directly asked about these regulations.
WhatsApp, owned by Meta, confirmed to WIRED that the instructions were meant exclusively for its internal support chatbot. The company attributed the exposure of the blocks to a technical error and stated that the restrictions were intended to prevent the bot from providing legal advice. All hidden blocks were removed from the public code by 18 October.
