This post from Bruce Schneier quoting Dan Goodin at Arstechnica is pretty scary – known vulnerabilities in WhatsApp unfixed, 400,000 accounts being hacked every day at one stage. WhatsApp started as a great alternative to email and SMS – secure, fast, free, easy to use – but has gradually deteriorated since Facebook acquired it. If I could avoid it completely I would, but convincing other people to change their workflow is a big deal and isn’t going to happen quickly.
I recommend Signal instead. It’s very similar from a user perspective, except run by people who actually understand security and privacy. Unfortunately it seems hardly anyone has heard of it. Check it out!
