Native DNS Spoofer (Example)

Created

Description

This module provides a Rex based DNS service to resolve queries intercepted via the capture mixin. Configure STATIC_ENTRIES to contain host-name mappings desired for spoofing using a hostsfile or space/semicolon separated entries. In default configuration, the service operates as a normal native DNS server with the exception of consuming from and writing to the wire as opposed to a listening socket. Best when compromising routers or spoofing L2 in order to prevent return of the real reply which causes a race condition. The method by which replies are filtered is up to the user (though iptables works fine).

Development

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/spoof/dns/native_spoofer
msf auxiliary(native_spoofer) > show actions
    ...actions...
msf auxiliary(native_spoofer) > set ACTION < action-name >
msf auxiliary(native_spoofer) > show options
    ...show and set options...
msf auxiliary(native_spoofer) > 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.
