Hey Folks, today in this tutorial we are going to talk about a web application penetration testing tool called “broken-link-checker”. The code of this tool is written in Node JS language which comes with the below mentioned features.
Features
- Support for many HTML elements and attributes; not only and Support for relative URLs with .
- WHATWG specifications-compliant HTML and URL parsing.
- Honor robot exclusions (robots.txt, headers and rel), optionally.
- Detailed information for reporting and maintenance.
- URL keyword filtering with simple wildcards.
- Pause/Resume at any time.
Let’s test it 
!!
Required Dependencies
So first we have to install “npm” dependency which is usually not pre-installed in any operating system. npm is the package manager for Node. js and the JavaScript coding language.
1 | apt install npm |
Good 
!! Now we can easily install and configure any node js project using this utility like below.
1 | npm install broken-link-checker -g |
Done !! We think users will become experts by installing different tools with us. Well the tool has been installed and you can now operate it by just dropping its name on the terminal.
1 | blc --help |
Recursive and Ordered
Basically we just have to name the website we want to hunt down and add filters to get the results in recursively. Sometimes the external links of the website get expired and the owner of the website does not look at them even once and the reason for this carelessness can reward the hackers.

Exclude Internal Links
We think that searching internal links is not useful. Suppose even if we get it, we will exclude internal link search process which will reduce the search time and will give us quick and accurate results.
1 | blc https://secnhack.in -i |
Finally !! We have tested the rest of the features of this tool but they don’t seem useful so we gave up but you can try once yourself.
