What is happening was while using Facebook on the mobile, you get this pop-up message suddenly, and bringing you into a new page.
Let's be detective
Look closely to the address bar again. We always check the Domain name. Domain name for this page is "dovelane.com", rather than the proper one "whatsapp.com". What is dovelane? If you do not know the source, do not anyhow click on the request they sent to you.
So, this is what happen when you click on something from an unknown source to you.
Thanks for Facebook friend Leslie Chin, for sharing his personal story.
The following is the real and true official Whatsapp page that you should look into. "www.whatsapp.com".
Additional notes
You may be curious to know, if it is not from the real Whatsapp, why is there "whatsapp.dovelane.com" in the address bar?
That is what we called as sub-domain, apart from domain name itself. When we create a website, we need to register a domain name which is handled by ICANN, Registration of domain name has certain cost and charges.
However, subdomain is free. Once we have a domain name, we can have many different subdomain. For example like what you should have seen before, m.facebook.com, touch.facebook.com, and any name you can think of!
That's why, do not trust any website which its domain name is unknown!
Yup, that's simple as that:
- Always check the domain name.
- Never believe of what you see as the sub-domain. It can be any name.
