WhatsApp security issue that allows steal your numbers and messages

It has found a major flaw in an application that we all use: WhatsApp, the most popular messaging application. Hopefully resolve it soon, an important application and uses so many mA should be serious about security. The problem is:

"... It is the lack of encryption in the information. The gap is evident when using public WiFi networks (like an airport, for example). Apparently, although the web site boasts of using HTTPS, in reality the data are unprotected by any security protocol. The problem is that although the information comes out of the 443-designated port for encrypted traffic-servers WhatsApp receive it as plain text.

If you use software like Wireshark, it is easy to hang from the wireless network, and thus, access the directory of phone numbers, and even remove the messages exchanged. This is a very important decision, because practically all the information is likely to be removed for lack of protection. "
