What I owned
End-to-end engagement work: recon, targeted testing, verification, structured reporting with reproducers and screenshots, severity classification per VRT (Bugcrowd Vulnerability Rating Taxonomy), and remediation recommendations. Recent finding categories: missing rate limits enabling LLM-token financial DoS, public exposure of FastAPI auto-docs (/openapi.json, /docs, /redoc), legacy TLS acceptance, information disclosure through health endpoints, body-size and parameter validation gaps, and prompt-injection / RAG-poisoning surfaces on Zendesk AI agents.
Constraints
- Black-box external testing only — no source-code access
- Strict scope adherence per engagement brief
- Safe-harbor compliance (CFAA, DMCA, ToS)
- Disclosure rules vary per program (some allow write-ups, some do not)
Process
- 01
Recon
Surface mapping via DNS, certificate, and HTTP/TLS reconnaissance. Endpoint enumeration via documentation surfaces and intelligent fuzzing within scope.
- 02
Targeted testing
Per-finding test plan with reproducers. Each finding verified independently before submission.
- 03
Evidence capture
Reproducer commands, response samples, and annotated screenshots for every finding.
- 04
Structured reporting
VRT severity, impact statement, reproducer, evidence, and recommended fix per finding. Markdown + DOCX delivery.
- 05
Triage handoff
Clear, scoped submissions designed to pass triage on first review.
Approach
Bug bounty work pays for clarity, not volume. A clean report with one critical and three majors out-converts a flood of duplicates and informational notes. The discipline is in scope adherence, reproducer quality, and writing impact statements that the triage engineer can act on without a follow-up email.
Deliverables
- Round 2 submission on omnisee.io: 14 findings (1 critical, 4 major, 9 minor) with reproducers and screenshots
- Active Zendesk Managed engagement on Bugcrowd targeting AI agents, Copilot, and App Builder
- Markdown + DOCX report formats per engagement preference
- Reproducer scripts for every finding
- Severity-classified, VRT-aligned reporting
- Remediation guidance for every finding
Outcomes
- 14 verified, independently reproducible findings on a single target in one engagement round
- Critical-severity finding (LLM-token financial DoS) with full reproducer and impact statement
- Active Zendesk Managed engagement on a premium-rated scope ($5,000–$50,000 P1)
- Reports designed to clear triage cleanly — structured severity, evidence, and fix guidance
What it feels like
Reports are designed to survive a fast triage read: severity at the top, reproducer in three lines, impact in one sentence, fix in two.
