#tag:-A Simple Recon Workflow for Beginner Bug Hunters

Description

I have prepared a basic step-by-step workflow beginners can follow when starting reconnaissance on a target.

A structured reconnaissance workflow helps bug bounty hunters investigate targets efficiently. Instead of randomly testing a website, researchers follow a sequence of steps to gradually reveal the attack surface.

The process usually begins with identifying the main domain provided by the bug bounty program. Next, subdomain enumeration tools are used to discover additional domains associated with the organization. These domains may host APIs, staging environments, or legacy services.
Once subdomains are collected, the next step is verifying which hosts are active. Live hosts can then be analyzed for directories, parameters, and technologies used by the application. These details often reveal potential areas where vulnerabilities may exist.

By following a consistent workflow, beginners can organize their reconnaissance efforts and ensure that no potential entry points are missed during their security testing.

#tag:-Why Documentation Is Important for Security Researchers

Explanation on how documenting discoveries and tools improves learning and credibility in bug bounty.

Documentation plays a critical role in the development of every security researcher. As bug hunters explore targets, test tools, and learn new techniques, recording these experiences helps build a structured knowledge base.

Many researchers maintain documentation through repositories, personal blogs, or technical write-ups. These records help them remember commands, workflows, and observations discovered during reconnaissance or vulnerability testing. Over time, the documentation becomes a valuable reference for future engagements.
Sharing knowledge publicly also strengthens a researcher’s credibility within the security community. Platforms such as blogs or code repositories allow hunters to demonstrate their learning progress and technical understanding. This transparency helps establish trust with bug bounty platforms and organizations.

For beginners, documenting even small discoveries or setup guides is an excellent habit that improves both learning and professional visibility.

#tag:-Common Vulnerabilities Beginners Should Learn in Bug Bounty

Description

A quick overview of beginner-friendly vulnerabilities frequently discovered in bug bounty programs.

For newcomers to bug bounty hunting, focusing on a few common vulnerabilities can make the learning process much easier. Many successful reports come from relatively simple issues that are overlooked by developers.
Cross-Site Scripting (XSS) is one of the most widely reported vulnerabilities. It occurs when user input is not properly sanitized and allows attackers to inject malicious scripts into a web page. Another common issue is Insecure Direct Object Reference (IDOR), where attackers can access data belonging to other users by modifying identifiers in requests.
Open redirect vulnerabilities are also frequently found. These occur when applications redirect users to external sites without proper validation. Although simple, they can be used in phishing campaigns.

Understanding these vulnerabilities helps beginners recognize patterns in web applications and improves their ability to identify security weaknesses during testing.

#tag:-Understanding Reconnaissance in Bug Bounty Hunting

An introduction to reconnaissance and why it is one of the most important phases in bug bounty research.

Reconnaissance is the foundation of every successful bug bounty investigation. Before testing a system for vulnerabilities, researchers must first understand the structure of the target. This process involves collecting information such as domains, subdomains, endpoints, and technologies used by the application.
Many bug hunters begin with subdomain enumeration to identify additional assets owned by the organization. These assets often expose forgotten services or outdated applications that may contain security weaknesses. After gathering subdomains, researchers verify which hosts are live and then search for parameters, directories, and APIs.
Effective reconnaissance allows a hunter to map the attack surface of the target. Instead of blindly testing the main website, the researcher focuses on areas where vulnerabilities are more likely to exist. In bug bounty programs, strong reconnaissance skills often lead to discovering hidden entry points that other testers might overlook.

Setting Up a Bug Bounty Hunting Environment in Termux
_**
Bug bounty hunting does not always require a powerful computer. With the help of Termux, security researchers can set up a lightweight reconnaissance environment directly on an Android device. Termux provides a Linux-like environment where many open-source security tools can run.
The first step is updating the system packages and installing essential utilities such as Git, Python, and Go. These allow researchers to install commonly used reconnaissance tools. After the environment is ready, tools like Subfinder, Httpx, and Nuclei can be installed to assist with discovering subdomains, identifying live hosts, and scanning for potential vulnerabilities.

Although mobile environments have limitations compared to full Linux systems, they are excellent for learning the bug bounty workflow. For beginners, Termux offers a practical way to start practicing reconnaissance and understanding how modern bug hunters gather information about target systems.
