WhatsApp has taken an unusual approach to PR in the last 24 hours, and announcements of a security issue have been widely distributed in News apps and websites, such as the BBC or Mashable. But no mention on WhatsApp’s own website, Facebook, Twitter or Instagram as far as we can currently see.
Their website says here, under the title of Security by Default, WhatsApp's end-to-end encryption is available when you and the people you message use our app. Many messaging apps only encrypt messages between you and them, but WhatsApp's end-to-end encryption ensures only you and the person you're communicating with can read what is sent, and nobody in between, not even WhatsApp. This is because your messages are secured with a lock, and only the recipient and you have the special key needed to unlock and read them. For added protection, every message you send has its own unique lock and key. All of this happens automatically: no need to turn on settings or set up special secret chats to secure your messages.
They have issued a new version of the app, and given it has 1.5 BILLION users, the best advice is to update your app ASAP. Here’s how.
Just do it. No, that’s Nike. Never mind, still just do it.
