The former top security executive at WhatsApp filed Monday a US federal lawsuit alleging that parent company Meta systematically violated cybersecurity regulations and retaliated against him for reporting the failures.
Attaullah Baig, who served as head of security for WhatsApp from 2021 to 2025, claims that approximately 1,500 engineers had unrestricted access to user data without proper oversight, potentially violating a US government order that imposed a $5 billion penalty on the company in 2020.
