2025 Bug Bounty Methodology, Toolsets and Persistent Recon
In this blog, I explore how bug bounty hunting is changing in 2025, with an emphasis on modern techniques, more intelligent toolkits, and the effectiveness of persistent reconnaissance.
The article describes a modern, comprehensive strategy to bug hunting, which includes scope definition, asset discovery, vulnerability triage, and efficient reporting. I also draw attention to the trend towards automation and human creativity, where strategic thinking is supported by technologies but not replaced.
Key sections include:
- 2025 Methodology: Modular workflows tailored for high-signal hunting, emphasizing efficiency and precision.
- Toolsets: A look at updated and newly adopted tools for asset discovery, fuzzing, API testing, and vulnerability validation.
- Persistent Recon: How continuous, low-noise recon helps surface hidden assets and edge-case vulnerabilities that others miss.
1. Reconnaissance
Tools:
Amass: Comprehensive subdomain enumeration.
Subfinder: Fast passive subdomain discovery.
Assetfinder: Collect domains from various sources.
httpx: Probes for active HTTP services.
Chaos Dataset: Public bug bounty domains.
Pro Tips:
- Chain tools via Bash to automate recon (e.g., subfinder → httpx → nuclei).
- Maintain recon scripts using
cronor tools like ReconFTW or LazyRecon.
2. Vulnerability Scanning
Tools:
Nuclei: Fast and flexible template-based scanner.
Nikto: Web server misconfigurations.
Dalfox: XSS and injection scanner.
SQLMap: Automated SQL injection discovery and exploitation.
Techniques:
- Write custom Nuclei templates for program-specific issues.
- Combine with wordlists (
SecLists,PayloadsAllTheThings).
3. Web Exploitation
Tools:
Burp Suite (Community or Pro) with extensions like:
Turbo Intruder, Autorize, JS Miner, Param Miner
FFUF: Directory brute-forcing and fuzzing.
GF (Grep Patterns): For finding vulnerable parameters in URLs.
x8: SSRF & open redirect scanner.
Exploitable Weaknesses:
· IDORs (Insecure Direct Object Reference)
· Authentication bypass
· Business logic flaws
· Race conditions (use Turbo Intruder)
4. Subdomain Takeovers
Tools:
- Subjack, Subzy, Nuclei templates for takeover detection.
- Check CNAME entries pointing to unclaimed third-party services.
5. Source Code & JavaScript Analysis
Tools:
LinkFinder: Finds sensitive endpoints in JS files.
JSParser, SecretFinder
Burp JS Miner extension
Semgrep
Method:
· Look for hardcoded API keys, tokens, internal endpoints, secrets.
· Use relative path traversal to locate internal files.
6. API Testing
Tools:
Postman or Insomnia for manual API interaction.
Kiterunner for brute-forcing API endpoints.
Burp Suite + Repeater/Intruder for param tampering.
JWT Tools
Look for:
· Broken object level authorisation (BOLA)
· Rate limit issues
· JWT flaws
7. Authentication & Access Control
Test for 2FA bypass, privilege escalation.
Use Autorize or AuthMatrix in Burp.
<<Tactical Advice👍>>
· Pick a niche (e.g., SSRF, mobile, APIs) and specialize.
· Watch recon daily — targets evolve.
· Monitor program changes, new acquisitions, subdomains, and DNS records.
>>>Tools are only one aspect of bug bounty hunting; additional skills include curiosity, persistence, and inventiveness. Your path is accelerated by tools like Nuclei, Burp Suite, and Amass, but the true treasure is found in your approach and frame of mind. Act like a pro, yet think like a hacker.
