Reading Time: 3 Minutes PretenderYour MitM sidekick for relaying attacks featuring DHCPv6 DNS takeover as well as mDNS, LLMNR and NetBIOS-NS spoofing.

Pretender is a tool developed by Red Team Pentesting to obtain machine-in-the-middle positions via spoofed local name resolution and DHCPv6 DNS takeover attacks. It primarily targets Windows hosts, as it is intended to be used for relaying attacks but can be deployed on Linux, Windows, and all other platforms Go supports. Name resolution queries can be answered with arbitrary IPs for situations where the relaying tool runs on a different host than pretender. It is designed to work with tools such as Impacket’s ntlmrelayx.py and krbrelayx that handle the incoming connections for relaying attacks or hash dumping.

To perform local name resolution spoofing via mDNS, LLMNR and NetBIOS-NS as well as a DHCPv6 DNS takeover with router advertisements, simply run pretender like this:

https://www.blackhatethicalhacking.com/wp-content/uploads/2022/07/SS1-2.png
You can disable certain attacks with –no-dhcp-dns (disabled DHCPv6, DNS and router advertisements), –no-lnr (disabled mDNS, LLMNR and NetBIOS-NS), –no-mdns, –no-llmnr, –no-netbios and –no-ra.

If ntlmrelayx.py runs on a different host (say 10.0.0.10/fe80::5), run pretender like this:

https://www.blackhatethicalhacking.com/wp-content/uploads/2022/07/SS2-2.png

Pretender can be setup to only respond to queries for certain domains (or all but certain domains) and it can perform the spoofing attacks only for certain hosts (or all but certain hosts). Referencing hosts by hostname relies on the name resolution of the host that runs pretender. See the following example:

For more information, run pretender –help

* Pretender can be configured to stop after a certain time period for situations where it cannot be aborted manually (–stop-after and main.vendorStopAfter)
* Host info lookup (which relies on the ARP table, IP neighbours and reverse lookups) can be disabled with –no-host-info or main.vendorNoHostInfo
* If you are not sure which interface to choose (especially on Windows), list all interfaces with names and addresses using –interfaces
* If you want to exclude hosts from local name resolution spoofing, make sure to also exclude their IPv6 addresses or use –no-ipv6-lnr/main.vendorNoIPv6LNR
* DHCPv6 messages usually contain a FQDN option (which can also sometimes contain a hostname which is not a FQDN). This option is used to filter out messages by hostname (–spoof-for/–dont-spoof-for). You can decide what to do with DHCPv6 messages without FQDN option by setting or omitting –ignore-nofqdn
* Depending on the build configuration, either the operating system resolver (CGO_ENABLED=1) or a Go implementation (CGO_ENABLED=0) is used. This can be important for host info collection because the OS resolver may support local name resolution and the Go implementation does not, unless a stub resolver is used.
* The host info functionality is currently only available for Windows and Linux.
* A custom M[...]

AC address vendor list can be compiled into the binary by replacing the default list hostinfo/mac-vendors.txt. Only lines with MAC prefixes in the following format are recognized: FF:FF:FF<tabVendorID<tabVendor (the MAC prefix length can be arbitrary).
* If you only want to perform Kerberos relaying you can specify –no-lnr and –spoof-types SOA to ignore any queries that are unrelated to the attack.
* When conducting a Kerberos relay attack where krbrelayx.py runs on a different host than pretender (relay IPv4 address points to different host that runs krbrelayx.py), the host running krbrelayx.py will also need to run pretender in order to receive and deny the Dynamic Update query sent to the relay IPv4 address. Building and VendoringPretender can be build as follows: go buildPretender can also be compiled with pre-configured settings. For this, the ldflags have to be modified like this: -ldflags '-X main.vendorInterface=eth1'For example, Pretender can be built for Windows with a specific default interface, without colored output and with a relay IPv4 address configured:

GOOS=windows go build -trimpath -ldflags '-X "main.vendorInterface=Ethernet 2" -X main.vendorNoColor=true -X main.vendorRelayIPv4=10.0.0.10'
