Block any number sending you this kind of message.
Hacking WhatsApp is not a easy deal.
Keep calm and use your own Internet/wifi
Don’t use public WiFi, that’s the only way someone can break into your system.
Keep your phone nearby, so that people can’t access OTP sent to you for verification.
Momo challenge is a hoax created by some criminals,
Don’t follow what they says, maximum things they can do to you is they will send a violent image to your number.

They (Momo) can’t do anything with your information.
Don’t fall in the trap.
