BackBox Linux

What is BackBox

BackBox is an open source Ubuntu based Linux distribution. Its main purpose is to provide a desktop environment for network and systems analysis, penetration and security assessment. It is a community project and full of some of the most commonly used security and analysis tools. It runs a desktop environment based on the XFCE window manager, which makes it very easy to use.

Installing and Tuning

System requirements for the latest version (4.7):

32-bit or 64-bit processor
1024 MB of system memory (RAM)
10 GB of disk space for installation
Graphics card capable of 800×600 resolution
DVD-ROM drive or USB port (3 GB)

Since this is a free and open sourced project, BackBox Linux .iso file can be downloaded from the projects homepage. The installation and tweaking of the system follows up the usual Ubuntu/Debian guide lines. To access the security applications, use the 'Auditing' option.

After the installation, the user can start configuring and using the services available in this operating system. This can be achieved by simply left-clicking on the blue 'B' button on the upper-left corner.

To manage applications, Synaptic Package Manager or Ubuntu Software Center can be used.

Securing BackBox itself

Anyone wanting to use this OS for security purposes should start off by securing BackBox itself first. As it is an Ubuntu based Linux OS, the foundation for basic OS security should be:

- Strong passwords

- Immediate and frequent security updates

- Usage of official repositories, as much as possible

- Enable firewall (UFW is integrated but disabled by default in BB)

- Disk encryption and backups

- Common sense

One good eye should always be on user privileges as well, although BackBox does make extra sure to warn the user every time a security issue might arise with this (like warning users about consequences of using certain programs with root, or making sure the programs can only be used by users in certain groups).

There is no need for antivirus software in BlackBox, unless file sharing with other operating systems, like Windows, is active.

When using a web-browser like Mozilla, add-ons like Adguard, No-Script, BetterPrivacy should be installed.

Java and Flash should be disabled.

There is also an alternative to UFW - FirewallD, which has to be downloaded manually. It is more complex and has extra features, like Network Zone Management.

This OS also has AppArmor, an application-level firewall. It confines programs to a limited set of resources.

Information Gathering

Gathering information should be the first step in any security project. Without it, it would be hard to evaluate any system.

Some of the tools used in BackBox for information gathering are:

Arping

This utility sends ARP requests to the hosts on a specific subnet.

Example command:

sudo arping -I eth0 -c 3 192.168.1.1

This finds out the reachability of an IP on the local Ethernet. The '-I' identifies the intended interface, the '-c' is the count of the ARP requests taken.

Arp-scan

This is a simple but very powerful command-line tool that can be used for system discovery and fingerprinting. It assembles and sends ARP requests to specified IP addresses, displaying any responses that are received.

Example use is finding all local IP's and MAC addresses with this command:

sudo arp-scan -l

Knock

This is a Python script, written by Gianni 'guelfoweb' Amato, designed to enumerate sub-domains on a target domain through a word-list.

Example command would be this:

knockpy domain.com

This would start looking for the aforementioned site's subdomains. This is helpful if you are looking for subdomain takeover vulnerabilities.

Nbtscan

This is an application to scan and get information about IP networks for NetBIOS name information.

theHarvest

This is an information collector used to harvest e-mails, subdomains, hosts and personal information about individuals.

Example command:

theharvester -d domain.com -b google

This would print all the email addresses in the site 'domain.com' that can be found by the google search engine.

Zenmap

Zenmap is a multi-platform graphical Nmap frontend and results viewer. This GUI is designed to make Nmap - Network Mapper, an open source tool for network exploration and security auditing - easy for beginners while also giving experienced Nmap users advanced features.

Zenmak can be started by searching for it from the services menu or typing it in the command line:

sudo zenmap

In the opened window, type the ip address of the host that you want to scan in the Target field and select the desired profile from the Profile drop-down box:

To find the scanned host’s list of open ports, port states, the services corresponding to the ports and it’s version details etc., click on the Ports/Hosts tab.

Also it will get you the host details as well. Click on the Host Details tab in the Zenmap main interface.

To scan your entire network, just enter the ip address series (ex. 192.168.1.0/24) of your network in the Target field of the Zenmap window. Click on Scan to start scanning your whole network.

The types of scans are:

- Intense scan

Quickly scans the most common TCP ports. Will also try to determine the type of OS and services running.

- Intense scan plus UDP

Same as the regular Intense scan, just that we will also scan UDP ports.

- Intense scan, all TCP ports

Normally Nmap scans a list of 1000 most common protocols, but this will leave no TCP ports (from 1 to 65535) unchecked.

- Intense scan, no ping

This scan will not ping the host and assumes it is up. Will be useful if the target has blocked ping requests.

- Ping scan

Pings the target, no port scanning.

- Quick scan

Scans only the 100 most common TCP ports.

- Quick scan plus

Quick scan with OS and version detection.

- Quick traceroute

Scan that can be used if it is nescessary to determine hosts and routers in a network scan. It does so by tracerouting and pinging all hosts defined in the target.

- Regular scan

A scan that will issue a TCP SYN scan for the most common 1000 TCP ports, using ICMP Echo request (ping) for host detection.

- Slow comprehensive scan

Command: nmap -sS -sU -T4 -A -v -PE -PP -PS80,443 -PA3389 -PU40125 -PY -g 53 –script “default or (discovery and safe)” <target>

Works similarly to 'Intense scan plus UDP' only with some extra features.

A lot of focus will be put into host detection, continuing even if the initial ping request fails. Three different protocols will be used to detect the hosts - TCP, UDP and SCTP. If host detection has succeeded, it will do its best to determine what OS, services and versions the host are running based on the most common TCP and UDP services. Also the scan camouflages itself as source port 53 (DNS).

Other

Other Information gathering tools in BackBox are:

- Recon-ng: This is a full-featured Web Reconnaissance framework.

- WhatWeb: This is an application that recognizes web technologies including content management systems (CMS), blogging platforms, statistic/analytics packages, JavaScript libraries, web servers, and embedded devices.

- Creepy: This is a web application security assessment report generator.

Vulnerability Assessment

After the information is gathered, the next step should be to analyze it. That's where vulnerability Assessment tools come into play. With them, you can identify the vulnerabilities present in systems and prioritize them.

OpenVAS

This is a framework composed of several services and tools to deliver a comprehensive, powerful vulnerability scanning management solution.

To start off, a new admin account user should be created:

openvasmd --user=admin --new-password=new_password

To run OpenVAS, simply choose 'OpenVAS GSA' on the menu list or go to your localhost with the port given to OpenVAS (default is 9392).

You will be promted with a login screen (Accept the self-signed SSL certificate). From there, enter the details of the user you created above and the OpenVAS web interface will open:

In the opened window, create a new task and fill in the information required - type in either the name or the IP of the domain you want to target for the scan. Then click start. Once it has finished, a report will be created. You can better analyze it by exporting it to different main popular file formats such as .pdf, .txt or .html.

OpenVAS will have grouped the possible vulnerabilities into high-, medium-, low- and log-level (information). These reports are not false proof but they help with simplifying the security assessment.

Nikto

This is an open-sourced web server scanner. It performs comprehensive tests against web servers for multiple items, including over 6700 potentially dangerous files/programs, checks for outdated versions of over 1250 servers, and version specific problems on over 270 servers. It also checks for server configuration items such as the presence of multiple index files, HTTP server options, and will attempt to identify installed web servers and software.

Example commands:

nikto -h 10.0.2.15

This scans the target host with the ip '10.0.2.15'.

nikto -T x 6 -h http://site.com

This performs only a specific type of check against the target. In this case, a denial-of-service check. The types (and more) are written in the man file of nikto.

nikto -Display V -o results.txt -Format txt -Tuning 4 -h 10.0.2.15

This performs an injection test and saves the result as a plain text file while also displaying a Verbose output in the terminal.

Skipfsh

This is an active web application security reconnaissance tool. It prepares an interactive sitemap for a targeted site by undertaking a recursive crawl and dictionary-based probes.

Example command:

Skipfish –o /user/desktop http://targetwebsite.com

This scans the target website and creates an output file on the location specified by '-o'.

To get a list of which tests Skipfish does, visit the Google Code Archive Wiki.

ZAP

OWASP Zed Attack Proxy tool is one of the most popular web application vulnerability finders. The main features of this tool are:

- Proxy intercepting - Configuring your browser so that it sends all the requests and responses through ZAP. The responses and requests can also be intercepted and changed.

- Active scanners - Performs wide range of scans on the application.

- Passive scanners - Examines requests and responses and sometimes detects problems from doing this. It is 'safe' to use and it runs all the time.

- Spider - Crawls the application to find links that are usually hidden.

- Report Generation - Generates reports of the issues found and directs to helpful pages from where you can learn how to solve them.

- Brute Force - Using OWASP Dirbuster Tool, this feature can find files even if there are no links to them.

- Fuzzing - For finding more subtle vulnerabilities that the automated scanners cannot usually find (using fuzzdb and OWASP JBroFuzz)

- Extensibility - Adding additional functionalities to ZAP (code.google.com/p/zap-extensions)

To use it, type in the website you want to test on the 'URL attack' bar and press 'attack':

Other

- RIPS: This is a static source code analyzer for finding vulnerabilities in PHP web applications.

- Cvechecker: The main purpose of this tool is to automatize security check by generating reports about possible vulnerabilities in your system by comparing the result with the information in its common vulnerability environment (CVE) database.

Exploitation

This is the process of where the weakness found in the system is penetrated. This is achieved by using exploit, an automated script designed to attack the target system.

Sqlmap

This is an automated tool to detect SQL ﬂaws. SQL-Injection is usually the most common forms of attacks and usually very effective in getting data from the target.

Example commands:

sqlmap -u http://www.examplesite.com --dbs

This command tries to find databases in the specified site.

sqlmap -u ”http://www.examplesite.com" --cookie="security=low; PHPSESSID=l0ng4m0un10fnumb3rs4ndl3tt3rs" --dbs

This command tries to find databases from the specific site while keeping the session active using the mentioned cookie.

BeEF

Short for The Browser Exploitation Framework, it is a penetration testing tool that focuses on the web browser. It allows the professional penetration tester to assess the actual security posture of a target environment by using client-side attack vectors.

BeEF can be started from the services > auditing > exploitation menu

You need to click on one of the UI URL-s, which will open the BeEF login page on your browser.

]

Type in the default username and password (beef & beef). This will open the startup page, where you can get the overview of the tool.

You can test this program out by running an apache server on your BackBox and creating a a simple script to hook a the intended website with BeEf. The result of this would make information about the browser used available to the BeEF user, like the browser components, the running scripts and hardware information. On the 'commands' tab in the BeEF GUI (after you chose the active IP address from the left menu), you can extract even more data and manipulate the ongoing browser session. For example, you can redirect the intended URL to another site.

Armitage

This is the graphical frontend of the Metasploit Framework. It is a scriptable red team collaboration tool. It has a server component to allow a team of hackers to share their accesses to compromised hosts.

To start it, type 'armitage' in your terminal. This will open up a new window:

Click connect and if the tool asks you if you want to start Metasploit RPC server, click 'yes'. This will open the Armitage GUI:

From this, you can create custom attacks against a host. For example, you can test out yous skills on a virtual machine maintained by the Metasploit project team.

Fimap

This is a python tool which can find, prepare, audit and exploit bugs in webapps.

Example command:

sudo fimap -u "http://IpOfWebApp/index.php"

This will try to find bugs in the mentioned url of the webapp.

Others

- MSF: This is a useful auditing tool that contains a lot of exploits and a development environment to modify or create them.

- Htexploit: This is a useful tool to exploit the .htaccess files

- Joomscan: This is a tool that detects file inclusion, SQL injection, and command execution vulnerabilities of a targeted website that uses Joomla.

- W3af: This is a GUI-based web application attack and audit framework to find and exploit the vulnerabilities detected.

- Wpscan: This is a BackBox WordPress vulnerability scanner.

Privilege Escalation

This occurs when you have gained access to a system but have not gained enough privileges to gather useful information or make necessary changes.

John

This (also known as John the Ripper) is a password cracking software tool written in C.

You can start of by simply typing this in the terminal:

john --test

This will test the program to find it's capabilities on the current OS.

Another way of testing this program out is by creating a 'password.text' file on you system containing password format with a valid hash:

user:AZl.zWwxIh15Q

Then simply run john on the file (warning - this program is CPU-intensive and the password-cracking process can take a long time):

john password.txt

For systems, like Linux, that use shadow passwords - a system file in which encryption user password are stored so that they aren't available to people who try to break into the system - John offers an utility called 'unshadow', which can be used to create a file from /etc/passwd and shadow files.

unshadow /etc/passwd /etc/shadow > mypasswd.txt

If the cracking process is successful, the tool will write the password to ~/.john/john.pot. This file isn't human readable but with john you can still do it:

john --show mypasswd.txt

Xhydra

A GTK+ based GUI for hydra, this is a parallized login cracker which supports numerous protocols (such as TELNET, FTP, HTTP, HTTPS, HTTP-PROXY, LDAP, SMB etc.) to attack by using the Telnet module. This tool gives researchers and security consultants the possiblity to show how easy it would be to gain unauthorized access from remote to a system. This can also be very useful to a hacker in the scenario where one has cracked a wifi password and gained local access to the network.

To start the program, type 'xhydra' in your terminal. This will open the GUI:

]

Type in the target IP or the target. Choose whether you'd like to use IPv6, choose the port and protocol. And tick the optional boxes in the 'output options', for example, when you want to enable verbose output or debug mode.

In the password menu tab, type in the username (like 'admin') and a commonly used password ("password", blank, "admin"). In most cases though, you would want to use a wordlist. A wordlist can be found by simply googling one. Then save it as a list file (like 'password.lst') and define it's path in the password list box (for example: ".\user\password.lst").

In the 'tuning' tab menu, you can choose, for example, a time when the attack will be finished or if the attack will stop once first valid login credentials are found. You can also use a proxy.

In the 'specific' tab menu, you can, for example, define in what directory the protected page is on the server by defining it in the '"http / https url" (use, for example, a simple "/").

Then all that is left is to start the tool, wait for the results and analyze them.

Ettercap

This is a free and open-sourced tool for man-in-the-middle attacks. It has a user-friendly GUI interface and supports passive and active dissection of the amount of protocols.

Ettercap can work with these four models:

- IP-based: Filtered packets by IP address. - MAC-based: Filtered packets by MAC address. - ARP-based: It is very useful for sniffing packets between two hosts on a switched network. - PublicARP-based: It is very useful for sniffing packets from a user to all hosts.

Some important features are:

- HTTPS support - OS fingerprinting - Passive scanning - Hijacking DNS

Ettercap provides four user interfaces:

- -T use text only GUI
- -C use curses GUI
- -G use GTK+ GUI
- -D daemonize ettercap (no GUI)

To use ettercap, you must specify a Networking Interface Card (NIC). This can be done with the command:

ifconfig -a

As mentioned above, ettercap uses Man-in-the-Middle attack method. This is done by arp-spoofing - an attack technique, where an attacker sends a fake ARP message to the local LAN. The goal of ARP spoofing is to hijack a system and an attacker wants to join his MAC address with the IP address of another host. The result is that any traffic meant for that IP address will be sent to the attacker.

In the ettercap GUI, from the sniff menu, choose "Unified Sniffing" and then the network interface in the opening window.

The next step is host scanning. Click the "Hosts" menu and then click "Scan for hosts". When the scan is finished, click the "Hosts" menu and then click on "Host List":

If Ettercap found any hosts on your network, it can be added as a target by clicking on it and choosing "Add to target 1".

Click the "Mitm" menu, select "Arp Poisoning", then select “Sniff Remote Connection” and click “OK”.

Finally, click the "Start" menu and select "start sniffing".

Tcpdump

A command line packet sniffer that prints out a description of the contents of packets on a network interface that match the boolean expression.

Command to capture data from a certain interface:

sudo tcpdump -i eth0

Commant that prints out all packets arriving or departing from host PC1:

sudo tcpdump host PC1

Command that prints all IP packets between PC1 and not PC2:

sudo tcpdump host PC1 and not PC2

Wireshark

Formerly known as Etheral, it is the world's foremost network protocol analyzer.

To start capturing packets with your user, first you need to make sure that your user belongs to the usergroup named 'wireshark'. To be sure of that, use this command:

grep 'wireshark' /etc/group

If your username does not appear in the following output, it is not part of the group. To add your user to the group, use the following command:

sudo usermod -a -G wireshark yourusername

Now you can oped the Wireshark GUI, choose the network interface that is functional and start capturing and analyzing packets.

Tshark

A terminal oriented version of Wireshark. For example, to start off, you would want to know the available interfaces you can use with the command:

sudo tshark -D

An example of capturing network data with tshark:

tshark -eth0 -c 100 -w log.pcap

This will capture 100 network packets and save them into a file called log.pcap.

With the following example, we extract data from any HTTP request. The '-Y' is used to request filters, '-T' is used to specify the extract process and the '-e' is used to identify the wanted fields:

tshark -i eth0 -Y HTTP.request -T fields -e http.host -e http.user_agent

This command basically prints out the same output as Wireshark GUI:

tshark -r ~/dhcp.pcap -V frame.number == 1

Maintaining Access

Maintaining Access comes into play once we have gained access to a system. The tools in this category allow us to access it again without repeating all the tasks done initially.

Iodine

This is a free (ISC licensed) tunnel application to forward IPv4 traffc through DNS servers. This can be usable in different situations where internet access is firewalled, but DNS queries are allowed.

To use this tunnel, you need control over a real domain (like mytunnel.com), and a server with a static public IP number that does not yet run a DNS server. Then, delegate a subdomain (say, tunnel1.mytunnel.com) to the server. If you use BIND for the domain, add these lines to the zone file:

tunnel1host     IN      A       10.15.213.99
tunnel1         IN      NS      tunnel1host.mytunnel.com.

Start iodined on the server. Example:

iodine -f 192.168.99.1 10.0.0.1

The first argument is the tunnel IP address and the second is the assigned domain (in this case tunnel1.mytunnel.com). The -f argument will keep iodined running in the foreground, which helps when testing. iodined will start a virtual interface, and also start listening for DNS queries on UDP port 53. Either enter a password on the commandline (-P pass) or after the server has started. Now everything is ready for the client.

On the client side, just start iodine. It also takes two arguments, the first is the local relaying DNS server and the second is the domain used (tunnel1.mytunnnel.com). If DNS queries are allowed to any computer, you can use the tunnel endpoint (example: 10.15.213.99 or tunnel1host.mytunnel.com) as the first argument. The tunnel interface will get an IP close to the servers (in this case 192.168.99.2) and a suitable MTU. Enter the same password as on the server either by argument or after the client has started. Now you should be able to ping the other end of the tunnel from either side.

The normal case is to route all traffic through the DNS tunnel. To do this, first add a route to the nameserver you use with the default gateway as gateway. Then replace the default gateway with the servers IP address within the DNS tunnel, and configure the server to do NAT.

Scripts to configure the client can be found here.

Weevely

This is a stealth PHP web shell that simulates a telnet-like connection. The weevely modules ecosystem provides a working shell interface even with no shell command execution, replacing the standard shell commands (e.g. the file editors, cd and ls, SQL cli and dump, compression utilities, port scanners, etc.) with the weevely modules.

Example scenario: generating backdoor crypted code:

weevely -g -o <file path> -p password

With this we generate a PHP shell in the intended file path.

After this, type 'ls' in your terminal, to see the created file.

The next step is to get this file in the intended webserver - which is considered hacking, so this is not to be done without permission!

If you have the file in the webserver, to connect to it, use the command:

weevely http://weburl/weevely.php password

And now you have access to the webserver with weevely module.

Other Useful Features

Anonymous mode

This feature allows the use of Tor as an integrated feature, so the users are guaranteed anonymity when they surf the web.

To achieve this, push the blue button on the upper left corner, search 'tor' and then choose 'tor start' (or use the terminal command 'sudo service tor start'). After this, start the anonymous application, located at anonymous > anonymous start (or run terminal command 'anonymous start'). When this is done, you need to configure (with admin privileges) your /etc/tor/torrc file and add the following to it:

VirtualAddrNetwork 10.192.0.0/10
AutomapHostsOnResolve 1
TransPort 9040
DNSPort 53

After this, restart the tor service:

sudo service tor restart

Then start the anonymous application again. In the opened terminal window, the application will let you know that it has stopped the service network-manager, killed certain processes to prevent leaks and changed your MAC address (anonymous cannot change the MAC address in a virtual machine). Then it will ask weather the local hostname should be changed and if traffic should be transparently routed through tor. After this, you can check your settings with the command:

anonymous status

You can check weather your tor service is operable by going to check.torproject.org. You can also check weather your IP address has changed by going to whatismyipaddress website.

RAM wiping

BackBox also offers it's users the option to wipe the computer's RAM at shutdown/reboot. Simply search for 'RAM Wiping' on the services menu and turn it on. Pulling the PC's cord usually does the trick, but this feature makes extra sure that no data can be recovered.
