A lot of talk went down yesterday about a new way to exploit WhatsApp and bypass the end-to-end encryption the company likes to mention that it has whenever it can. I've seen tweets and comments that run the gamut from "it's FUD" to talking about some backdoor that Facebook had installed.
The good news is that it's neither. In fact, it's not really one of those things you need to be concerned about and instead is one of those things that make you wonder how it ever happened in the first place because it's pretty sloppy. But don't worry — it will be fixed long before anything happens.
