      First thing first, we are talking about this app "Bolo Messenger - Secure Chat, Voice & Video Calls" which is the new version of the #Kimbho app https://play.google.com/store/apps/details?id=com.bolo.chat …

      When you send a message with the #Bolo app, it is checking if your contact is online with this request. The endpoint is taking the "contact userId" (the 1st black rectangle in the picture)pic.twitter.com/lEqch4vpFa

      If the request is successful, you will receive this response with 2 info: - If the user is online - Last active time Let's try to have the status of someone which is not my contact!pic.twitter.com/Zlz6JjwYDS

      In this other request, the app is putting your phone number in the "contacts" parameter. If the request is successful you will receive a response with your userId.pic.twitter.com/euB3xCcXjM

      Magic time: 1) In the previous request, replace the "contacts" parameter by the phone number of someone which has a Bolo account 2) In the response, you will receive his userId 3) Use this userId in the 1st request I mentioned in the thread

      Even if you don't have it on your contact list you will receive his online status and last active time. Not good for a so called "secure" chat app, nah? What do you think @KamalAditi?

      That’s a shocker. You can do better than that. Wondering why whatsApp has the same security flaw, checkout this screenshot from whatsApp. This is an unknown number and I can see his status, omgpic.twitter.com/0pMt0VN9JA

      You have some issue to take a screenshot on your iPhone lol... For info, you can see his status because your “test” phone is in your contact...

          I don’t need to be a PROGRAMMER to see whatsapp status. Why would I write a hacking script for something I can do in simple 2 steps. Looking for something interesting.

          The issue is if you can do programmatically, you can extract large list of data continuously anf monitor list of unknown ph number. With whatsapp you have to add each number and check manually. Are you saying both are at same risk level?

          Elliot one can even the status of unknown number on WhatsApp, provided that unknown has not changed the privacy settings for 'last seen'.
