WhatsApp help pages exposed hidden instructions for Meta's AI support chatbot, including 'WHAT NOT TO SAY' rules

Around 80 WhatsApp help and FAQ pages contained about 100 blocks of hidden instructions for Meta's AI support chatbot in their underlying code, according to an analysis by privacy company Redact. The instructions told the chatbot not to recommend contacting data protection authorities or regulators, and not to reference legal documents or privacy laws such as GDPR, LGPD and CCPA. Meta said a bug caused the exposure. It removed the text after an inquiry from WIRED and said the instructions were meant for the chatbot, not users.
