Scope Review: Tracking Public Bug Bounty Scopes from One GitHub Repository

Scope: Aggregated Bug Bounty Target Data

You scan for bug bounties or do OSINT, and you'll know the drill. Platform scope pages change, new domains pop up, old assets vanish, subsidiaries appear quietly, and regional infrastructure shows up before anyone blogs about it.

Scope aims to cut that manual drudgery. It aggregates public program scope data from multiple bug bounty platforms, such as HackerOne, Bugcrowd, and Intigriti.

Scope isn't a vulnerability scanner, not a recon engine. It is a curated list of public targets. It feeds your recon workflow. For those with subdomain enumeration, screenshotting, passive DNS, and fingerprinting already dialed in, Scope is a handy addition to the toolkit. It saves you a few searches.

The following features are included: aggregated public program scope data, a single GitHub repository, and a simple, useful tool. Scope provides a list of targets, helping with your workflow.

What Scope Does and Who It Is For

Scope aggregates public in-scope assets from platforms such as HackerOne, Bugcrowd, Intigriti, and YesWeHack into one GitHub-based dataset. Instead of opening each platform separately and reviewing program pages one by one, you get a central repository of scope files that can be searched, cloned, filtered, and pulled into scripts.

Scope is a natural fit for bug bounty hunters, recon operators, and OSINT practitioners. Bug bounty hunters can identify legal targets quickly without wasting time bouncing between program dashboards. Recon operators can use fresh seed lists for domain expansion, asset clustering, and platform-wide monitoring. OSINT practitioners can map exposed attack surfaces, especially when they care about how public-facing scope changes over time.

The expectation to set is that Scope is a scope collection and update mechanism. It is not a scanner. It will not enumerate subdomains for you, fingerprint technologies, or discover exploitable issues. It gives you raw target intelligence in a form that is easier to work with than the original source platforms, HackerOne, Bugcrowd, Intigriti, YesWeHack.

The distinction between Scope and other tooling matters because some tooling gets oversold as automation magic. Scope saves time at the ingestion stage. In real recon work, that is a meaningful job, but it is still only one job.

How Scope Works in Practice

No changes needed. The text is already quite straightforward and concise. Here is the text as is:

The project automates data refresh from bug bounty platforms using GitHub Actions. It pulls public scope data and updates the repository roughly every 10 minutes. The data lives in a public Git repo. It's versioned and updated often enough to monitor.

That changes the workflow immediately.

Pull targets straight from a repo. No more hopping between HackerOne, Bugcrowd, Intigriti, and others. You get combined files, platform-specific files, wildcard lists, domain lists, and even out-of-scope material. This helps you avoid bad assumptions.

If you're comfortable with shell pipelines, you can start filtering by business unit, top-level domain, or regional assets.

GitHub hosting is where this repo shines. A public repo means you can clone, diff, grep, archive, and integrate into your automation. No more scraping a changing web UI for a current seed list. You pull from a version-controlled source that's friendly to scripts and easy to inspect manually.

The versioning helps with OSINT work. Historical comparison is a nice side effect. Even without change-monitoring features, the Git workflow makes detecting changes easier than most bug bounty dashboards. You track changes over time.

Where Scope Helps Real Recon Workflows

Use Cases for Scope

Target list generation is the most obvious use. Scope provides a single place to begin enumerating subdomains with domains, wildcards, or related assets.

Public programs list domains, wildcards, and related assets. A wildcard domain can seed subdomain enumeration. A new root domain may warrant ASN review. A GitHub repository entry can lead to developer asset mapping.

None of this is automatic. Scope cuts the time spent finding legitimate starting points.

Asset Inventory and Monitoring

Scope helps with asset inventory and monitoring. Public scope updates reveal new additions: domains, subsidiaries, staging environments.

The changes in these updates are often more interesting than the static list. Tracking additions over time helps teams spot organizational changes earlier. Recon teams see movements teams miss when they only check occasionally.

Legal Boundary-Setting

Scope is valuable at the legal boundary-setting stage. Analysts need to know what's in scope, what's excluded, and what requires extra caution.

Scope centralizes asset lists. You still read live program rules. You spend less time finding the program.

OSINT Perspective

Public bug bounty data has a use beyond hunting bugs. Organizations describe and expand their digital estate through this data.

One of the better uses of public bug bounty data is watching how organizations evolve. Not just hunting, but watching.

Strengths That Make Scope Worth Using

Strengths of Scope

Time savings are the biggest win. You'd otherwise spend hours manually checking bug bounty platforms for scope changes. Repetitive tasks get postponed. Scope consolidates updates into a single pull.

Data portability is another strength. Hosted on GitHub, scope lists are easy to inspect, clone, and diff. You can plug them into automation. Interfaces matter less than being able to compose tools. Scope behaves like infrastructure.

Updates are frequent. That matters if you care about new programs or changing scope. A repository that refreshes often is more useful than a stale dump.

Transparency

The files are public. You can inspect the data structure. No black-box API or opaque layer. For skeptics, that's a plus.

Limitations and Risks to Understand

Scope relies on upstream public data. Omissions, inconsistencies, and formatting issues from source platforms carry over.

Incomplete or oddly structured program pages mess up downstream data. A program page change may cause scope data to reflect that.

Raw scope entries aren't the full legal picture. Bounty rules, exclusions, and disclosure constraints can change outside the asset list. A domain listed in a text file doesn't mean all testing methods are permitted.

Manual validation still matters. Before testing, confirm the target against the live program page. Scope is a shortcut, not a compliance source.

This community project on GitHub is not official. A smaller star count doesn't make it bad. Evaluate it as a useful resource, not ground truth. Convenience is good. Mistaking convenience for authority gets people sloppy.

How to Use Scope Safely and Effectively

The safest way to use Scope is as an intake layer.

Pull targets from the repository, use them to seed passive workflows, then cross-check targets against the live bounty program page. This step is necessary for legality and program compliance.

Scope pairs well with passive DNS, subdomain enumeration, screenshotting, and change-monitoring tools. The repository provides raw scope lists. Passive DNS expands them. Enumeration tools find exposed subdomains. Screenshotting sorts web assets from dead hosts. Tech fingerprinting helps prioritize assets.

Teams should archive snapshots or diffs. This turns Scope into a historical record of public scope changes. For OSINT analysts, this surfaces acquisitions or newly exposed environments. For bug bounty teams, it shows when a target became testable.

Used this way, Scope works. It solves a workflow problem: getting current public scope data without wasting time.
