Hello guys,
today I want to show you, how you are able to stalk unknow telephone numbers. WhatsApp is sending the API data to the whole world.
With the script, you can see the telephone number, profile picture and the status. This is possible, because a lot of people are not changing their privacy settings. The script just simply access the data from an open API.
This is how it works:
1.Login to WhatsApp- Web and load the script in the developer console (F12):
2.Enter a phone Number
3.Know you can see all Numbers that are in your searched Area. People which are online, are at the top
When you don’t want that this happens with your data, change your security-settings to "only friends" or "nobody".
Most people have this option on default.
