Fetch all urls using waybackurl , here I we will go through if we need to lookup some particular parameter we will utilize tool:

  • echo “” | waybackurls |tee output.txt | grep -iE  “url=”

As above command we use echo to deploy our target waybackurls our tool, tee refer as output we want o save  grep we use for regex that we need particular endpoint parameter it will filter  “url=”.

Now run waybackurls without regex :
  • echo “” | waybackurls | tee output.txt
  • cat output.txt

As above we used Cat command to read output file :

Now, Utilize dalfox to find out XSS here we need to install dalfox
  • go get -u
