Sherlock OSINT Project – Username Investigation

Sherlock OSINT Project – Username Footprinting Using Kali Linux

In this project, I explored how to use Sherlock, a powerful OSINT tool, to search for usernames across hundreds of online services. Sherlock helps identify where a particular username may exist on the internet, providing valuable insight for digital investigations and security research.

Below are the exact steps I followed to install and run Sherlock on Kali Linux.

Steps I Followed

Update Your APT Sources:
First, I made sure my APT sources were correctly configured by opening the sources list file:
```
sudo nano /etc/apt/sources.list
```
Inside the file, I confirmed it contained the following line for Kali Rolling:
```
deb http://http.kali.org/kali kali-rolling main non-free contrib
```
Update Your Package List:
Next, I refreshed my package lists to ensure I had the latest information about available packages:
```
sudo apt update
```
Install Sherlock from APT:
I installed Sherlock using the following command:
```
sudo apt install sherlock
```
Run Sherlock:
Once installed, I ran Sherlock to search for a username across multiple platforms. To display results directly in the terminal, I used:
```
sherlock [username] --print-found
```
