The Nostromo Bug Bracker is an open source security tool designed for continuous bug bounty hunting and reconnaissance. It automates information gathering, vulnerability discovery, and target tracking to help security researchers work more efficiently.
Developed by the community, the tool focuses on reducing manual effort while increasing coverage during the early stages of engagements. This article explores its capabilities, workflows, and practical use cases.
| Feature | Description | Benefit |
|---|---|---|
| Automated Recon | Runs passive and active enumeration across multiple data sources | Saves time and uncovers hidden assets |
| Subdomain Discovery | target domainsIdentifies potentially vulnerable or overlooked subdomains | |
| Service Fingerprinting | Detects technologies, versions, and misconfigurations | Guides focused testing and exploitation |
| Report Export | Generates structured findings in multiple formats | Simplifies documentation and client communication |
Subdomain Enumeration Techniques
Passive Data Sources
The tool queries certificate transparency logs, search engines, and public datasets to collect subdomains without directly interacting with the target. This approach minimizes noise and detection risk.
Active Probing Methods
When allowed by scope, it performs DNS brute forcing and zone transfers to validate records and discover non-indexed endpoints. Results are merged with passive data for a unified view.
Vulnerability Correlation Workflow
After discovery, Nostromo Bug Bracker links gathered assets with known vulnerability databases. This correlation highlights outdated services, deprecated protocols, and common misconfigurations relevant to bug bounty scopes.
The engine assigns risk scores based on severity indicators and asset exposure. Researchers can prioritize high-impact findings such as exposed admin panels or deprecated libraries with known exploits.
Target Tracking and Organization
Each engagement is organized into projects that store notes, evidence, and associated findings. Tags and statuses help teams manage multiple programs and avoid duplicate efforts.
Integrated timelines show when each asset was enumerated and tested, supporting auditability and collaboration among researchers.
Reporting and Evidence Management
Structured reports group findings by host, severity, and technology. Screenshots, request and response samples, and linked data make it easier to validate bugs during submission phases.
Export options include PDF, Markdown, and JSON, enabling integration with other tools or direct upload to bug bounty platforms.
