Wow it seems there is no security at all: > By providing any WhatsApp registered telephone number and the text for the status update, it is possible to change a user's status. This action does not require any prior authentication or authorization > (on registration) The vendor has implemented bruteforce protection by locking a number after 10 tries. This step makes a successful attack on a specific number unlikely but an attacker bruteforcing X00 numbers can still guess X number(s) on average. > As published in the past several times already the XMPP traffic from WhatsApp is not encrypted. And they are planning to charge money for it? edit: perhaps even worse is their response to the security vulnerability seen in the timeline - they knew about the bug since 09-14
