Bugcrowd University: A Slide-and-Lab Curriculum for Bug Hunters

What Bugcrowd University actually is, and who it is for

The README describes Bugcrowd University as "a free and open source project to help level-up our security researchers," with content modules aimed at "the most critical and prevalent bugs that impact our customers." That framing matters. This is not a tool, a scanner or a framework. It is a set of teaching materials maintained by Bugcrowd for people who submit reports to bug bounty programs, and the intended reader is a researcher who already knows how to use a browser's developer tools and wants to move from random probing to a repeatable method.

The audience is narrower than the phrase "open source education" suggests. Each module carries slide content, a video and, for some topics, a lab guide. The modules listed in the README cover an introduction to the program, how to write a good submission, Burp Suite at introductory and advanced levels, broken access control, cross site scripting, recon and discovery, server side request forgery, GitHub recon and sensitive data exposure, and XML external entity injection. If your interest is cloud misconfiguration, mobile reversing or binary exploitation, nothing here addresses it. The curriculum is web application security with a Burp Suite centre of gravity.

A second audience is less obvious: trainers. The licence is CC-BY-4.0, so the slides can be reused and adapted with attribution. A security team building an internal onboarding deck can lift the access control material and credit the authors rather than writing from scratch. That is a legitimate use the README does not spell out but the licence permits.

How the repository is organised and how a learner moves through it

The repository is a flat collection of directories, one per module, plus an assets/ folder and a LICENSE.txt. The top level contains Access_control_testing/, An_introduction_to_Burp_Suite/, Burp Suite Advanced/, Cross_site_scripting/, GitHub Recon/, How_to_make_a_good_submission/, Introduction/, Recon and Discovery/, Server Side Request Forgery/ and XML External Entity Injection/. There is no build system, no package manifest and no index file beyond README.md.

The README's module table is the actual navigation layer. Each row pairs a module name with a link to a PDF in the repository, a link to a video hosted on bugcrowd.com, an optional lab guide PDF, and the authors' Twitter handles. The data flow for a learner is therefore: read the README table, click through to a slide PDF, watch the corresponding recording, then work the lab guide where one exists. Only two modules in the main table list a lab guide, Broken Access Control Testing and Cross Site Scripting, both pointing at PDFs named with the BOSS prefix. Everything else is slides plus video.

That structure has a consequence worth stating plainly. The repository stores the slides but not the videos. The video column points at bugcrowd.com resource pages, so the recordings live on Bugcrowd's site and the repository cannot guarantee they stay reachable. A fork preserves the PDFs and loses the lectures. The README also carries a Previous Work section listing older conference talks, including How to Shot Web from DEF CON 23 and The Bug Hunter's Methodology 2.1 from Nullcon, with slides hosted on Google Docs and Google Drive rather than in the repository. Those links are the most fragile part of the whole collection.

Getting the materials and running your first module

There is nothing to install. The README gives no install steps because the deliverable is documents. You obtain the content by cloning the repository or downloading individual PDFs from the GitHub web interface, then opening them in any PDF reader. The commands below are the standard git route; the repository name and default branch are as they appear in the project metadata.

git clone https://github.com/bugcrowd/bugcrowd_university.git
cd bugcrowd_university
ls

After the clone you should see the module directories listed in the README, including Access_control_testing/, Cross_site_scripting/ and Recon and Discovery/, alongside LICENSE.txt and README.md. If you prefer not to clone, the README's table links directly to each PDF on GitHub, and those links can be opened in a browser.

A sensible first pass is the submission-writing module, because it changes behaviour immediately. Open the PDF under How_to_make_a_good_submission/ and read it before your next report. The file is named "Bugcrowd University - How to Make a Good Submission.pdf" in the README's link.

For a hands-on topic, the access control module is the one with a lab. The README links two PDFs from that directory: the slide deck and a lab guide whose filename begins with BOSS. The lab guide is a document describing exercises, not a downloadable virtual machine, so budget time to stand up whatever environment the guide assumes. If you want the video alongside it, the README points to the Broken Access Control Testing resource page on bugcrowd.com; the repository holds no copy.

Where the curriculum stops short

The most concrete limitation is coverage. The README's Planned Modules table contains a single row reading "To Be Determined" with placeholder values in every other column. That is the entire roadmap. There is no schedule, no list of topics under consideration and no way to tell whether a module on, say, authentication flaws is coming. Anyone choosing this curriculum should treat the ten listed modules as the complete set.

Maintenance is another boundary. The last push to the repository was on 2026-08-26, which is recent, so the project is not abandoned. But a push date says nothing about whether the content was revised; the modules are PDFs, and a PDF diff is invisible in a commit summary. There are also no releases, so there is no version to pin and no changelog describing what changed between one state of the slides and the next. If you cite a slide in internal training, you cannot point at a version number.

The lab situation deserves emphasis. Only two modules in the main table carry a lab guide, and the naming suggests those labs run on Bugcrowd's BOSS environment rather than locally. The README does not document how to obtain that environment, whether it is open to non-customers, or what happens when it is unavailable. A learner who wants reproducible, self-hosted exercises will find this collection thin, and the README is silent on the question.

Finally, the video dependency is a single point of failure. Slides without narration lose the worked examples. Since the recordings sit on bugcrowd.com and the repository only links to them, the durable part of this project is the PDF set, not the full course.

How it compares with PortSwigger's Web Security Academy

The obvious alternative for the same audience is PortSwigger's Web Security Academy. The difference in approach is structural rather than a matter of quality. PortSwigger's academy pairs each topic with a hosted, browser-based lab that you solve and that validates your answer, and the lab environment is the product. Bugcrowd University pairs each topic with a slide deck and a recording, and the lab, where it exists, is a PDF guide pointing at Bugcrowd's own platform.

That produces different failure modes. With PortSwigger you get immediate feedback but you practise against their deliberately vulnerable applications. With Bugcrowd University you get the reasoning behind a bug class, the reporting expectations that come with a bounty platform, and modules such as How to Make a Good Submission and GitHub Recon that PortSwigger does not frame the same way, because Bugcrowd is teaching its own submission culture. The recon and discovery module and the GitHub sensitive data exposure module are closer to a hunter's workflow than to a lab syllabus.

A reasonable position is that the two are complementary rather than competing. Use Bugcrowd University for the methodology and the reporting side, and a lab-based academy for the muscle memory. If you can only pick one and you have never exploited anything, pick the lab-based option first, because reading a deck about SSRF does not teach you to find one.

Licence, reuse and the cost of keeping it current

The repository is licensed CC-BY-4.0, stated in the LICENSE.txt at the top level. For a training deck that is unusually permissive: you can copy, redistribute and adapt the slides, including commercially, provided you give attribution. The README identifies the creators as @jhaddix and @swagnetow and lists contributors including @chloemessdaghi, @jeffboothby, @samhouston and @danaepp, so attribution has concrete names attached. This is not legal advice; if you plan to rebrand the material or bundle it into a paid product, read the licence text yourself and check how the attribution requirement applies to your format.

Note that the licence covers the repository contents. The videos are hosted on bugcrowd.com and the archived talks link out to Google Docs and YouTube, so those items sit outside the CC-BY-4.0 grant even though the README links them.

The upgrade cost is low in the technical sense and awkward in the practical one. There is no dependency to bump and no migration to run. You pull the repository and you have the current slides. The awkward part is that you cannot diff the learning outcome: a refreshed PDF looks like any other PDF, and with no releases there is no changelog to read. If you maintain a fork for internal training, you will need to compare the module folders against upstream yourself to notice revisions.

Editorial conclusion

Adopt Bugcrowd University if you are a new or intermediate researcher who wants a structured reading order through the common bug classes, or a team lead assembling internal training from permissively licensed slides. Do not adopt it if you need a runnable lab environment, a graded curriculum or versioned releases; the repository ships PDFs and links, and the lab guides depend on Bugcrowd's own hosted BOSS platform. Before committing, open one module folder such as Access_control_testing/, confirm the slide PDF and lab guide both download, and check that the linked video still resolves on bugcrowd.com, because the repository itself provides no offline copy of the recordings.
