I work at a company that I strongly suspect had a very serious security breach because of Whatsapp.

During the outage, we were back to SMS and direct phone calling only. After the system was restored, back to how everything was before, caution be damned, lessons not learned.

It’s not bad enough to have that invasive application as the default means of passing information around (messages, photos, video and even audio, of all things!) on work phones, office personel has it paired to their computers, where highly sensitive programs and data is stored.
