Usage Examples

Scans for and, if found, attempts to cat /etc/passwd

Scans all hosts listed in the file ./hostlist with the default options

Python 2.7+


  • Identify and respond correctly to HTTP/200 response – false positives – Low priority/hassle
  • Implement curses for *nix systems – For the whole application or only psuedo terminal? – Low priority/prettiness.
  • Thread the initial host check now that multiple targets are supported (and could be make this bit time consuming)
  • Change verbose to integer value – quiet, normal, verbose, debug?
  • Add option to skip initial host checks for the sake of speed?
  • Add a summary of results before exiting
  • Save results to a file? Format?
  • Eventually the idea is to include multiple possible vectors but currently only one is checked.
  • Add Windows and *nix colour support – Low priority/prettiness
  • Add a timeout in interactive mode for commands which don’t return, e.g. /bin/cat /dev/zero
  • Prettify – Low priority/pretinness (obviously)
  • Add support for scanning and explointing SSH and SMTP
  • Add SOCKS proxy support, potentially using from Rober Picard
  • Other stuff. Probably.
