A Shell-based workspace that wraps the HackerOne hunt cycle — scope documentation, phased recon, and templated reporting — for researchers operating strictly inside authorized program boundaries.
| Tool | DevCop95/bugbounty-lab101 — a scope-enforced bug bounty workspace for HackerOne researchers with a 400+ tool support arsenal and local practice lab |
| Category | offensive-security workflow / shell automation framework |
| Primary Use | Documenting program scope, running gated recon-to-report pipelines via bugbounty-hunter.sh, and producing HackerOne-format report.md files during authorized hunts |
| Safe Use | For authorized bug bounty programs with documented permission, local lab VMs, and internal security assessments with written authorization |
| Telemetry Note | Because the pipeline drives standard tools like nmap, ffuf, and nuclei, defenders observe the usual scanning fingerprints; the workspace itself is client-side Shell and leaves logs under bugbounty/reports/ |
Most bug bounty tooling collections are grab bags of scripts that assume the operator already knows which program they are hunting and what its policy allows. bugbounty-lab101, a Shell-heavy workspace published under the MIT license with roughly 420 stars, inverts that assumption: the README is explicit that the workspace is built around the real HackerOne workflow — choose a program, document scope, scan within boundaries, chain findings, and report in a format triagers accept fast. The 400+ generic pentesting arsenal and local VM lab are positioned as support, not the entry point. That framing matters, because it makes scope enforcement an architectural property rather than an afterthought.
The core architectural insight is visible in the workflow diagram the README leads with. Everything flows from programs/*.md — plain Markdown files holding the exact scope copied from the HackerOne policy — through a gate labeled bugbounty-hunter.sh, and only then into scanning, ending at a templated report.md. The scope check is described as blocking execution if the target is not documented. In other words, the workspace treats an undocumented target as a hard failure state, which is a discipline many hunters claim but few toolchains actually enforce mechanically.
Operationally, the main entry point is bugbounty-hunter.sh with a handful of subcommands. ./bugbounty-hunter.sh new program-name scaffolds a scope tracker; ./bugbounty-hunter.sh scope target.com verifies membership and must return Scope OK before anything proceeds; ./bugbounty-hunter.sh full target.com runs the end-to-end pipeline covering recon, vulnerability scanning, brute forcing, secrets, API testing, and report generation; ./bugbounty-hunter.sh report target.com produces report-YYYYMMDD.md in the HackerOne template. The README also points to docs/hackerone-workflow.md for Hacktivity dedup checks and post-submission hygiene, which suggests the author has actually been through triage friction and encoded the lessons into the docs.
The second major component is the auto-scanner/ support arsenal, fronted by pentest.sh. It exposes a tool matrix (pentest.sh matrix), function-oriented search (pentest.sh search sql_injection), an express scan mode, and an installer for missing dependencies. The README organizes the arsenal into the now-standard eight-phase model: recon (nmap, amass, subfinder, gau, waybackurls), scanning (nikto, gobuster, ffuf), enumeration, exploitation, then business logic, API testing with swagger and graphql awareness, chain attacks, and finally report writing. Cloud recon tools like s3scanner and cloud_enum plus takeover checkers like subjack round out the reconnaissance category, which alone claims 50+ tools.
An interesting and somewhat unusual integration is T3MP3ST, a separate multi-agent framework by the same author that turns an AI coding agent into an offensive engine. The lab wires it in as an optional layer: you clone it, run npm install, place provider keys in t3mp3st/.env, and launch ./start-server.sh, which brings up a War Room UI at http://127.0.0.1:3333/ui/. A keyless mode lets local agents such as Claude Code or Codex connect without external API keys. The README credits the recon engine with a 90.1% pass@1 on XBEN and describes an 8-operator kill chain plus an evidence vault for persistent findings and retest tracking. Notably, T3MP3ST is deliberately .gitignored from the lab, keeping the AI layer decoupled from the deterministic Shell core.
From a defensive analyst's perspective, the telemetry profile is entirely conventional. The pipeline orchestrates stock tools — nmap, masscan, nikto, ffuf, sqlmap, nuclei — so blue teams see the expected scanning signatures in their WAF, DNS, and network logs. The genuinely novel observable is behavioral: a bugbounty-lab101 operator works a program methodically from documented scope files, which tends to produce clean, low-noise, well-correlated activity rather than opportunistic spraying. The optional passive enrichment through a pinned vendor/shodan_reconsx submodule pulls from Shodan CTL and scope-filters hostnames before any HTTP probing, which reduces gratuitous touch volume against out-of-scope assets.
The reporting side deserves its own comment. The included HackerOne report template maps findings to the H1 weakness taxonomy using CWE identifiers, and the workflow builds in a dedup check against Hacktivity before submission. This is where the workspace earns its keep for a professional: the difference between a paid report and an informational duplicate is often structure, severity reasoning, and reproducibility, and templating that consistently removes a whole class of triage-related rejections. The README's emphasis on report quality over tool count is a good sign that the author understands what actually closes the loop on a bounty.
For practice, the workspace includes a local VM lab so newcomers can exercise the full pipeline without touching real programs — a design choice that pairs well with the scope gate and reinforces the authorized-use posture throughout the documentation. The Important Rules and Troubleshooting sections, along with a changelog and learning resources list, indicate an actively maintained project rather than a one-shot script dump. The repository is written primarily in Shell, uses git submodules for some pinned tooling, and targets Kali Linux as its natural habitat.
Getting started is two commands deep: clone the repository, then chmod +x bugbounty/*.sh auto-scanner/*.sh followed by git submodule update --init --recursive if submodules did not come along. From there the natural flow is ./bugbounty-hunter.sh new to document a program, then verify with ./bugbounty-hunter.sh scope before anything touches the network. The workspace is best understood not as another scanner but as a governance layer over one — the part of bug bounty work that separates disciplined researchers from out-of-scope liabilities.
