Reports recently showed, a new bug has been discovered in WhatsApp that makes your phone number discoverable on Google search. The research found that the feature called ‘Click to Chat’ puts mobile numbers at risk.
Meanwhile WhatsApp, in an emailed statement to BGR said, “Our Click to Chat feature, which lets users create a URL with their phone number so that anyone can easily message them, is used widely by small and microbusinesses around the world to connect with their customers. While we appreciate this researcher’s report and value the time that he took to share it with us, it did not qualify for a bounty since it merely contained a search engine index of URLs that WhatsApp users chose to make public. All WhatsApp users, including businesses, can block unwanted messages with the tap of a button.”
