metasploitHelper and nmap2nessus released at Blackhat Asia Arsenal 2015

March 30, 2015 Leave a comment

@mgianarakis and me (@keith55) presented two new tools (metasploitHelper and nmap2nessus) at Blackhat Asia Arsenal in Singapore on 26th and 27th of March, 2015.

The tools were developed to help guys like us during vulnerability assessments and penetration tests.

Blog posts about the tools will be coming soon. Meanwhile, the information on the Github pages should be sufficient to get you started.
The tools are open source.  Feel free to contribute to the projects. Thank you



Pentesting Firebird Databases

January 9, 2015 Leave a comment

There seems to be limited information on pentesting Firebird databases on the Internet.
Firebird database server listens on TCP port 3050.

One good resource I found is

It seems like most people do not change the default SYSDBA credentials for their Firebird database. Below are the default credentials. 
Password: masterkey

I have encountered before that the access card database system was using Firebird database for its backend.
This python script requires pyfirebirdsql library from

Firebird requires you to supply the database name on the server you are trying to.
One way to get around it is to check for active connections on the Firebird database server.

What this tools does is to
1. Connect to the Firebird database server using the default credentials
2. List the connected databases
3. Dump the records from the Firebird database server

You can also use the -wordlist argument to supply it a wordlist of database names so that it can attempt to brute-force. That is useful if there aren’t any active connections (or databases not mounted) on the Firebird database that you are trying to access.

Below is a screenshot of the tool in action.

The common-tables.txt file from sqlmap is useful if you need a wordlist.

The tool can be downloaded from the below Github repo.

Test AS/400 for default credentials

December 7, 2014 Leave a comment

I wrote a simple script to test default credentials in AS/400. I made use of the library and sample code from  It currently only works with IBM AS/400 telnet servers for now.

You can pull the code from
You will have to supply the ip and port of the AS400 server in the command line

Corelabs Impacket Scripts (Modded)

September 9, 2014 Leave a comment

I made some changes to script due to some anonyances I encountered during peneration tests.

The use case scenario for these modded scripts is that if the password contains special characters like @ or : and you can’t use it with the default scripts (maybe its just me who can’t figure out how to know how to use them :P)

These 3 scripts ( are the common tools that you can use if you want to get the remote host to execute a meterpreter exe file generated via Veil-Evasion.

Using the modded scripts, you can get a list of hosts to run a single command (eg ipconfig) using one line of command.

The source code for the modded scriptscan be found here

Special thanks for Corelabs for making these scripts. Impacket scripts can be found here

Examples of how you can use the modded
python -d testdomain -u user -p pass -ip -command ipconfig
python -d testdomain -u user -p pass -ip -f ips.txt -command ipconfig

– Python2.7
– Impacket (svn checkout impacket-read-only)
– Ruby
– Veil Evasion (git clone


If you are working on a penetration test remotely, its sometimes hard to determine when the users start work or connect their laptops to the network.

winboxHunter is useful if you have managed to capture and cracked a bunch of NTLM credentails and want to run Metasploit against these windows boxes as and when they are connected to the network.

winboxHunter listens for NBNS broadcast packets so that when a new winBox is connected to the network, it will use the Impacket scripts ( and to push an executable onto the winBox and runs it.

In the background, winboxHunter runs Metasploit with payload handler (multi/handler) and listens for incoming connections from the winboxes.

You might want to modify autorunCmd.rc to specify the Metasploit commands you want to run on the pwned winbox upon connecting back to Metasploit.

See meterpreter.rc and autorunCmd.rc for more details.

If a host changes its IP address due to DHCP lease expiration, it will not attempt to exploit the winbox twice.

Format of password.txt

domain/username password


Meterpreter executable

You only need to use one of the below 2 options

– You can either use your own meterpreter payload executable using the -e or –exe argument (payload=windows/meterpreter/reverse_https, rport=8443) or

– You can use the -n or –enableVeil argument to generate a meterpreter payload executable using Veil Evasion
You can run winboxHunter using the below sample command

ruby winboxHunter.rb -n -f password.txt -v

When you run winboxHunter, a linux screen with the name “msfscreen” will be created and msfconsole will be executed. You can connect to the screen via the below command

screen -dr msfscreen

Medusa ‘combo’ word lists (default usernames and passwords) for SSH and Telnet services

August 16, 2014 Leave a comment is a useful resource that contains the default credentials for various devices.

I wrote a script that crawls, parses and extracts the credentials from and outputs them into the “combo” format as required by medusa. Medusa is a brute force tool for numerous services like MySQL, SMB, SSH, Telnet and etc.

Currently, only ssh and telnet related credentials are extracted from

You can download the “combo” word lists for ssh and telnet via the direct links below.

SSH combo list for Medusa

Telnet combo list for Medusa

Combined users.txt and passwords.txt that you can use with Patator ( which is another awesome brute force tool.

Sample command for medusa “combo” SSH attack.
medusa -M ssh -C wordList_ssh.txt -H port22.txt

If you would like to play around with the python script, you can download the file at the below location.


Patator is another awesome tool that you can use for brute forcing SSH logins

Sample command for patator SSH attack ssh_login host= user=FILE0 password=FILE1 0=users.txt 1=passwords.txt -x ignore:mesg=’Authentication failed.’


Special shoutout to for maintaining and providing the extensive database of default credentials at

Extended functionality for Burp Plugin – Carbonator

August 4, 2014 10 comments

I wrote a script to extend the functions of Burp plugin – Carbonator.

Carbonator is an awesome script by Integris Security. Carbonator uses Jython which is easy for me to understand.

Its similar to Sodapop by Redspin. However, the Sodapop script seems broken now.

Below is a link to Sodapop by Redspin

Below is a description for Carbonator from their website.
Carbonator’s purpose is to enable the ability to automate the vulnerability scanning of a large number of web applications.
A single command from a command line can now produce volumes of vulnerability information.

Carbonator can be found here

Burp Carbonator Extension Mod

I made some additional tweaks to the original script as well as created my own run script.

The additional functionalities that I have included are
1. Allow you to run Burp/Carbonator against a file containing a list of domain names/IPS/urls. Below is a screenshot of the file format.

Carbonator file input containing domain names/urls/ip

2. Run Bing lookup against the IP address of the domain name and find other websites that are hosted on the same IP address (using the IP:x.x.x.x keyword in Bing) and run Burp/Carbonator against these additional websites. These seems to be some false positives in Bing search engine. The script checks to make sure that the domain name resolves to the same IP address.

3. Search Google for links belonging to the domain name (using the keyword) in Google and run Burp/Carbonator against these links. You might find additional website content/links as compared to crawling

My Github repo for the code is at https// Please feel free to send me your feedback/comments. Thank you for reading.
