CEH Practical Notes

Module 02: Enumeration

  • ping www.moviescope.com –f –l 1500 -> Frame size

  • tracert www.moviescope.com -> Determining hop count

Enumeration using Metasploit :

  • msfdb init

  • service postgresql start

  • msfconsole

  • msf > db_status

  • nmap -Pn -sS -A -oX Test 10.10.10.0/24

  • db_import Test

  • hosts -> To show all available hosts in the subnet

  • db_nmap -sS -A 10.10.10.16 -> To extract services of particular machine

  • services -> to get all available services in a subnet

SMB Version Enumeration using MSF

  • use scanner/smb/smb_version

  • set RHOSTS 10.10.10.8-16

  • set THREADS 100

  • run

  • hosts -> now exact os_flavor information has been updated

Module 03 : Scanning Networks

  1. Port Scanning using Hping3: hping3 --scan 1-3000 -S 10.10.10.10 --scan parameter defines the port range to scan and –S represents SYN flag.

  2. Pinging the target using HPing3: hping3 -c 3 10.10.10.10 -c 3 means that we only want to send three packets to the target machine.

  3. UDP Packet Crafting hping3 10.10.10.10 --udp --rand-source --data 500

  4. TCP SYN request hping3 -S 10.10.10.10 -p 80 -c 5

    -S will perform TCP SYN request on the target machine, -p will pass the traffic through which port is assigned, and -c is the count of the packets sent to the Target machine.

  5. HPing flood hping3 10.10.10.10 --flood

  • msfconsole

  • use auxiliary/scanner/snmp/snmp_login

  • set RHOSTS and exploit

  • use auxiliary/scanner/snmp/snmp_enum

  • set RHOSTS and exploit

NetBIOS Enumeration (139) :

  • net use

  • net use \10.10.10.16\e ““\user:””

  • net use \10.10.10.16\e ““/user:””

  • NetBIOS Enumerator

Enum4Linux Wins Enumeration :

  • enum4linux -u martin -p apple -U 10.10.10.12 -> Users Enumeration

  • enum4linux -u martin -p apple -P 10.10.10.12 -> Password Policy Information

  • enum4linux -u martin -p apple -G 10.10.10.12 -> Groups Information

  • enum4linux -u martin -p apple -S 10.10.10.12 -> Share Policy Information (SMB Shares Enumeration

Active Directory LDAP Enumeration : ADExplorer

Module 05 : Vulnerability Analysis

  • nikto -h http://www.goodshopping.com -Tuning 1

  • Nessus runs on https://localhost:8834

    • Username: admin

    • Password: password

  • Nessus -> Policies > Advanced scan

  • Discovery > Host Discovery > Turn off Ping the remote host

  • Port Scanning > check the Verify open TCP ports found by local port enumerators

  • Advanced

    • Max number of TCP sessions per host and = unlimited

    • Max number of TCP sessions per scan = unlimited

  • Credentials > Windows > Username & Password

  • Save policy > Create new scan > User Defined

  • Enter name & Target

  • Schedule tab > Turn of Enabled

  • Hit launch from drop-down of save.

Module 06: System Hacking

NTLM Hash crack :

  • responder -I eth0

  • usr\share\responder\logs --> Responder log location

  • john /usr/share/responder/logs/ntlm.txt

Rainbow table crack using Winrtgen :

  • Open winrtgen and add new table

  • Select ntlm from Hash dropdown list.

  • Set Min Len as 4, Max Len as 6 and Chain Count 4000000

  • Select loweralpha from Charset dropdown list (it depends upon Password).

  • rcrack_gui.exe to crack hash with rainbow table

Hash dump with Pwdump7 and crack with ophcrack :

  • wmic useraccount get name,sid --> Get user acc names and SID

  • PwDump7.exe > c:\hashes.txt

  • Replace boxes in hashes.txt with relevant usernames from step 1.

  • Ophcrack.exe -> load -> PWDUMP File

  • Tables -> Vista free -> select the table directory -> crack

Module 08: Sniffing

  • http.request.method == “POST” -> Wireshark filter for filtering HTTP POST request

  • Capture traffic from remote interface via wireshark

    • Capture > Options > Manage Interfaces

    • Remote Interface > Add > Host & Port (2002)

    • Username & password > Start

Module 13: Hacking Web Servers

  • FTP Bruteforce with Hydra
