By plugging tens of billions of phone numbers into WhatsApp’s contact discovery tool, researchers found “the most extensive exposure of phone numbers” ever—along with profile photos and more. https://t.co/fHhmwl1mDs

🚨 MASSIVE: Researchers scraped 3.5 BILLION WhatsApp phone numbers using the app's contact discovery feature, along with profile photos and bios for millions of people. This would be "the largest data leak in history" if it hadn't been done by researchers 🧵

Grateful to be a part of this team that worked on this research. Thanks to @a_greenberg for covering our story.

Researchers tried plugging every possible phone number into WhatsApp's web app. They found they could collect 3.5 billion users' phone numbers, photos for half and profile text for almost a third, the biggest personal data exposure ever by some measures. https://t.co/ilOfmG9haa

@crypt0x_0 Integrating it directly in the app is nasty.

@BrongoCS Still crazy that Valves main goal here was to circumvent anti gambling laws in certain regions. as confirmed by their patchnotes a few hours ago.

@parzerp Makes sense. Its a new way of thinking. Like DB engineering or functional languages. But its just gonna make you a better engineer.

Proud to be part of the team that worked on this discovery 👀
