WhatsApp is easily the application I use the most on a daily basis on my smartphones. I use it for work, I use it to reconnect, and I use it to send silly memes to silly people all the time.
Odds are, WhatsApp’s probably super important to you too. But when something’s very important, there will be people who will want to exploit it for malicious purposes — especially considering the amount of information that gets shared via WhatsApp. And the bad news is that these bad people may have a way in if you’re not careful.
