WhatsApp allows users to send instant messages, images, and videos to friends. Users can also call, video chat, and post stories that last for 24 hours.
Why is it a risk?
Although Whatsapp primarily allows users to contact people that they already have contact details for (for instance, a stored number in their Contacts list, or an online friend) it is possible for users to be contacted by stangers who get hold of their number. These strangers will also be able to see the user's profile picture. Whatsapp does however provide good guidance for children and parents in relation to modifying privacy and location settings in order to allow protect the account holder. Further, users can block unwanted contact from nuisance numbers.
