WHAT IS BUG HUNTING
Bug bounty hunting is a career that is known for the heavy use of security tools. These tools help the hunters find vulnerabilities in software web applications and websites, and are an integral part of bounty hunting. Below is our top 10 list of security tools for bug bounty hunters..
WHAT IS KALI LINUX?
Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing. It is maintained and funded by Offensive Security. Kali Linux. Developer. Offensive Security.
Kali Linux is mainly used for advanced Penetration Testing and Security Auditing. Kali contains several hundred tools which are geared towards various information security tasks, such as Penetration Testing, Security research, Computer Forensics and Reverse Engineering
Overview of vulnerability exploitation
Exploitation involves using tools including the hundreds found within Kali Linux and code to take advantage of discovered vulnerabilities across different software, systems or applications. The tools involved are numerous, simple to advanced and are normally deployed to attack specific vulnerable services. Since these tools are diverse and can be applicable in a wide scope, we have divided the following sections, to cover the different categories in which these tools can be applied.
Understanding exploitation tools
Eexploitation tools are used in diverse environments and circumstances. It takes the skill, patience and knowledge of a seasoned hacker to know when it is right to use which tool. However, since most of these tools are open-source, people with basic knowledge of Linux commands and how operating systems and networks operate can run these tools against any system.
To avoid falling into trouble, we highly encourage you to only run the tools above within a controlled environment such as virtual machines and only practice against vulnerable machines such as webgoat, Damn Vulnerable Web Application (DVWA) and Buggy Web Application (BWAPP).
BUG HUNTING AND EXPLOITATION TOOLS
1. Burp Suite
The top spot on the list of security tools for bug bounty hunters belongs to Burp Suite, and for good reason. Burp Suite is an integrated security-testing platform for web applications that gives hunters what they need to get the job done. It allows you to perform scans on everything you want from full crawls to individual URLs and covers over 100 generic vulnerabilities. Burp Suite also supports many kinds of attach insertion points and nested insertion points. At the end of the day, Burp Suite offers a clear and comprehensive presentation of vulnerabilities. This is a paid tool and can be found
2. Reverse IP Lookup
Sometimes as a security researcher, especially for bug bounty hunters, all you have is an IP address to work with. This may seem trivial to the untrained eye, but experienced hunters know you can really do a lot with it. Hosted on DomainTools, Reverse IP Lookup will find all domains hosted on the IP, track domains that are coming and going, and output result data into .csv reports. IP lookups are free if you are a DomainTools Personal or Enterprise member. To give Reverse IP Lookup a go, click here.
Hosted on GitHub, DNS-Discovery is a great tool for the bug bounty hunter. This tool is a multithreaded (a breath of fresh air from some other similar tools) subdomain bruteforcer that uses a word list to concatenate with a domain to look for subdomains. DNS-Discovery allows for resolution and display of both IPv4 and IPv6.
4. Google Dorks
Google dorks is a solid go-to to use when searching for hidden data and access pages on websites. This tool relies in part on the part of the website indexing power of Google and this volume of data is useful for bug bounty hunters. Google Dorks also does a good job with network mapping and can assist in finding subdomains.
5. Vulnerability Lab
While not a “tool” in the purest sense, Vulnerability Lab is definitely a helpful website that hunters would do well to keep in the toolbox. Vulnerability Lab is a project that provides vulnerability research, vulnerability assessments and bug bounties. Among some of the most useful aspects are the web application vulnerabilities and website vulnerabilities. This would definitely be one of the first resources I would consult when beginning a bug bounty hunt.
HackBar is a security auditing/penetration tool that is a Mozilla Firefox add-on. Bug bounty hunters will find that this tool allows them to test site security, XSS holes and SQL injections. Some of the advantages of HackBar include:
- All HackBar functions work on text that you currently have selected
- Hashing of MD5/SHA1/SHA256
- Sandbox-like text area
- Useful MS SQL Server/MySQL shortcuts
If you are interested in HackBar, you can find it here.
Written in Python, Wfuzz is a tool that will help bug bounty hunters bruteforce web applications. Wfuzz is useful for sniffing out resources that are not linked such as directories and scripts, POST and GET parameter-checking for multiple kinds of injections, form parameter checking, fuzzing and other uses. Features that users will find attractive include:
- Default output is in HTML
- Capability to check multiple injection points
- Bruteforcing for all parameters
- Automatic/artificial request time delays
- Results can be hidden via word numbers, return code, line numbers and regex
When checking for vulnerabilities in your websites, IronWASP is going to quickly become one of your best friends. This web security scanner is open source and free to use, and more powerful than you think it would be for being so wallet-friendly. Some great features include:
- Login sequence recording is supported
- False-positive and negative-positive detection are supported
- Reporting is available in both RTF and HTML formats
- Easy to use and with a simple-to-understand GUI, even an inexperienced information security employee can quickly use it
If IronWASP has piqued your interest, you can find it here.
Not to be left out, mobile applications are definitely a contemporary area of interest for bug bounty hunters. One of the best among them is INalyzer for the iOS platform. Hosted by App Sec Labs, INalyzer makes manipulation of iOS applications a breeze. Tampering with methods and parameters is available and INalyzer can target closed applications, which means that your black-box project can now be considered gray-box. For more information on INalyzer, click here.
Wapiti is a command-line application tool that allows bug bounty hunters to audit the security of websites and web applications. Operationally, Wapiti crawls web applications with black-box scans and looks for points where it can inject code. When Wapiti finds a list of forms, form inputs and URLs, it acts like a fuzzer by injecting payloads to check for script vulnerability. Some notable features include:
- Server-side request forgery
- Reflected and permanent XSS injection
- Includes a buster module that allows for bruteforcing filenames and directories on a target web server
- POST HTTP and GET attack methods are supported
- The scan process includes an option to set maximum scan time
