A researcher, who claims to have found the event, calls it a privateness concern and says that it leaks almost three lakh telephone numbers of WhatsApp customers in plaintext. However, the problem is not as critical as it’s being portrayed within the media because it solely makes the telephone numbers of these customers searchable on Google who’ve chosen to make them public by producing their hyperlinks. Also, no names or different non-public particulars are popping in Google Search.

This omits the necessity of including a telephone quantity to your contact record to talk and offers a strategy to join with people on the messaging app instantly through the use of a hyperlink that features the telephone variety of the WhatsApp contact.

Having mentioned that, it is very important observe that other than telephone numbers, Google does not have a document of some other private information of customers who’ve used the Click to Chat characteristic of WhatsApp. Jayaram in some circumstances discovered that he was in a position to discover profile photos and profile statuses of the customers whose numbers are seen on search outcomes. However, these particulars are solely accessible if the customers have set their visibility for everybody and one has to open every contact contained in the WhatsApp to see their profile image, an arduous process.
