One can also see other details like name, address. ...

We will see osint way to gather online info about the target. In this post I will use various open source tools and technique for passive information gathering. Lets assume our target is shaquib izhar. All we have is this name and we need to find as much information about him as possible. We will start with simple Google Dorking. My first query will be “shaquib izhar” this will give all websites, URL where this specific name is available. Let’s see what result we get from this search. We got his twitter profile, quora and other social media accounts registered with this name. There’s also a link of about.me profile on Google search associated with this name. Let's go to that link and see if we can gather some another information. Below we can see there’s a connect with me LinkedIn link of his profile N ow, because I am using a VPN, whenever I follow that LinkedIn profile link, it is asking me to login to view that profile. And we can’t login because it can notify the user tha...
