WhatsApp introduces usernames to replace phone numbers, enhancing privacy after a 2024 data scrape exposed 3.5 billion numbers.
WhatsApp is rolling out usernames to replace phone numbers as a user identifier, addressing a security flaw exposed by Austrian researchers who harvested 3.5 billion phone numbers via WhatsApp’s browser interface.
The vulnerability, enabled by weak rate limiting, allowed automated scraping of numbers, profile photos, and text for millions of users.
Though Meta patched the issue with rate limits by October 2024, experts warn the data may already be exploited.
The move to usernames aims to reduce exposure risks and improve privacy, reflecting broader concerns over digital data security.
