Description

This module identifies NTP servers which permit "reslist" queries and obtains the list of restrictions placed on various network interfaces, networks or hosts. The reslist feature allows remote attackers to cause a distributed, reflected denial of service (aka, "DRDoS" or traffic amplification) via spoofed requests. The more interfaces, networks or hosts with specific restrictions, the greater the amplification. requests.

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/scanner/ntp/ntp_reslist_dos
msf auxiliary(ntp_reslist_dos) > show actions
    ...actions...
msf auxiliary(ntp_reslist_dos) > set ACTION < action-name >
msf auxiliary(ntp_reslist_dos) > show options
    ...show and set options...
msf auxiliary(ntp_reslist_dos) > 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.
