[User] What is ARP poisoning - Network topology?

[Assistant]
Besides the scenarios mentioned above, many network topologies exist and ARP poisoning attacks need to be carefully prepared based on that topology. Below are some common examples.

1. One segment: the client, the server, and the attacker are on the same network segment. The ARP tables can be poisoned with the attacker spoofing either the client or the server.
2. Two segments: the client and the attacker are on the same network segment but the server is on another one. For a hijacking attack, the client's ARP table can be poisoned with the attacker posing as the client's gateway. For a relaying attack, the gateway's ARP table also has to be poisoned with the attacker posing as the client.
3. Three segments: all three machines are on different network segments. For both hijacking and relaying attacks, I'm not sure what can be done... :man_shrugging:

[User] Explain ARP poisoning - ARP poisoning

[Assistant]
Bettercap's arp.spoof module has multiple options that allow multiple scenarios

* arp.spoof.targets is the list of targets whose ARP tables will be poisoned
* arp.spoof.internal is an option that allows bettercap to choose which addresses to spoof. If set to true, machines from the same subnet as the client victim will be spoofed (i.e. their IP addresses will be matched to the attacker's MAC address on the victim client's ARP table). To put it simply, this option needs to be set to true when the attacker wants to be the man-in-the-middle between two machines of a same subnet. When the victim client and the spoofed server are on different subnets, this option can be left to false.
* arp.spoof.fullduplex is an option that, when set to true, will make bettercap automatically try to poison the gateway's ARP table so that packets aimed at the victim client also get intercepted.
* arp.spoof is a trigger to set to on when starting the ARP poisoning, off when stopping it. This trigger will also enable packets forwarding (i.e. write 1 in /proc/sys/net/ip/ip_forward) while the arp.ban trigger will disabled that and the poisoned victim will not have access to the spoofed machines anymore.

[User] Tell me about ARP poisoning - Packet forwarding

[Assistant]
Bettercap also has the any.proxy module that has multiple options to allows multiple scenarios

* any.proxy.iface allows to set the interface to redirect packets from
* any.proxy.protocol can be set to UDP or TCP to specify on which transport protocol the packets to reroute will transit
* any.proxy.src_address refers to the destination address of the packets to reroute. This usually has to be set to the spoofed server IP address. Packets that were originally sent to that server will be rerouted and sent to another one. This option has to be set when doing the rerouting technique.This option can be blank. Bettercap will then reroute every packet received without filtering on the address. For instance, this is useful when doing a WSUS or DNS spoofing attack on multiple victims at the same time.
* any.proxy.src_port refers to the destination port of the packets to reroute. This usally has to be set to the spoofed service port. Packets that were originally sent to that server will be rerouted and sent to another one. This option has to be set when doing the rerouting technique.
* any.proxy.dst_address refers to the IP address the matched packets are to be sent to. For instance, when doing WSUS or DNS spoofing attacks in a rerouting technique mode, this option has to be set to the IP address of the attacker's server.

=== WSUS spoofing

ARP poisoning for WSUS spoofing in a two-subnets layout (attacker + client in the same segment, legitimate WSUS server in another one). Packets from the client to the WSUS server need to be hijacked and sent to the attacker's evil WSUS server. In order to do so, the attacker must pose as the client's gateway, route all traffic to the real gateway except the packets destined to the WSUS server.

The evil WSUS server needs to be started before doing ARP poisoning. The pywsus (Python) utility can be used for that matter.

`bash
python3 pywsus.py --host $network_facing_ip --port 8530 --executable /path/to/PsExec64.exe --command '/accepteula /s cmd.exe /c "net user testuser /add && net localgroup Administrators testuser /add"'

[System] You are a cybersecurity educator. Explain the requested concept, attack technique, or defense mechanism clearly and thoroughly, covering how it works, why it matters, and what tools or conditions are involved.

[User] What should I know about ARP poisoning - Combining ARP poisoning and IP spoofing to bypass firewall?

[Assistant]
The goal of this attack is to bypass the firewall protecting a sensitive network and be able the access an asset there.

To do so, the attacker's machine sits as MITM between the DNS server (referred to as the target of the ARP Spoofing, which is authorized to communicate with the sensitive asset in the protected network), and the firewall controlling the access to the protected network.\
In addition to this, the attacker spoofs the IP address of the DNS server when communicating with the sensitive asset and tags its traffic through dynamic ports to be able to track it and handle the response to its spoofed requests.

Below is a diagram to visualize the attack:

_Nota bene:_ there are different ways of populating the NAT table regarding outgoing traffic IP translation; through the POSTROUTING chain, applied on all outgoing packets:

1. MASQUERADE_:_ this will indicate that the source IP of outgoing packets should be changed to the one of the network interface specified in -o argument.

`bash
iptables -t nat -A POSTROUTING -o "NETWORK_INTERFACE" -j MASQUERADE
`

2. SNAT_:_ this will indicate that the source IP of outgoing packets should be changed to the one specified in --to argument. Below is an example different from the one used in the attack descried above, where decision on the NAT rule to apply is based on destination (-d option) rather than the source (-s option).
