Target Version & Username

  • After Downloading the file, I extrected the strings in a txt file $ strings pcap2.pcapng > out.txt
  • In a normal view, It was a WP site.
  • Than i directly search for Version using GREP $ grep -n version out.txt , and got the Wordpress Version version="****"
  • After that i searched for common keywords using the same command $ grep -n keyword out.txt and in a keyword log i found the username and password log=username&pwd=password .
