Update WhatsApp immediately or get hacked, Says WhatsApp.
If you are using WhatsApp, then we recommend you to immediately update your WhatsApp version (both iOS and Android) to the latest version, this is because a vulnerability (a bug) has been found by Israeli security firm NSO. This bug which when used will cause your device to be hacked, with just a call on your WhatsApp. The interesting part of it is, whether you attend the phone call from that unknown number or not, a hacker can install spyware (a program that can be used to spy people) apps remotely, without your permission and can read your messages, emails, location, almost everything that you had given WhatsApp to access.
