OFFPORT_KILLER : Tool Aims At Automating The Identification Of Potential Service Running

OFFPORT_KILLER tool aims at automating the identification of potential service running behind ports identified manually or on services running locally only.

The tool is useful:

  • When nmap or any scanning tool is not available and in the situation during which you did a manual port scanning and then want to identify the services running behind the identified ports and
  • also if you have been able to identify services running locally via (netstat, running processes SNMP or else).

Several databases are used such as the one from NMAP, IANA and linux machines.

The tool can be used by pentesters, system admins, CTF players, students, System Auditors and trolls :).

Usage

  • Example

./OFFPORT_KILLER.sh -i inputfile.txt -r report.txt -e /tmp/

Arguments

  • -i : input file (format IP:PORT)
  • -r : report name (save the output)
  • -h : help

Steps

  • Step 1: Peform a manual port scanning (using nc, tcpdump or whatever) or identify services running locally
  • Step 2: Create a file with format IP:PORT (where IP is the target IP address and PORT is a port identified).
  • Step 3: Run the tool with the file created using the argument -i

Note: Create an entry for each port, several IP can be input in the file.
