| # OffsecCyber-Thinking — reasoning-optimized web-security SFT |
|
|
| A **thinking-mode** supervised fine-tuning set for web application security / bug-bounty models (Qwen3-style `<think>` + tool-calling). Reasoning-dominant and grounded: CVE-metadata **recitation was deliberately dropped** to reduce hallucination. |
|
|
| ## Composition (9,417 records) |
| | grounding | count | source | |
| |---|---:|---| |
| | grounded | 4,001 | Exploit-DB verified webapps, PoC extracted from the real exploit files | |
| | authored_curated | 2,500 | offensive/web-appsec instruction data | |
| | real_report | 2,000 | HackerOne-style reports | |
| | authored | 643 | synthetic tail-class + modern-stack + negatives (think + tool-calling) | |
| | grounded_lab | 273 | PortSwigger labs | |
| |
| - **`<think>` share: 49%** · **negatives: 7.5%** · tool-calling trajectories included. |
| - Splits: train 8,475 / valid 470 / test 472, **leakage-safe** (grouped by CVE/EDB/report-id/hash), 0 cross-split leaks, 0 fabricated/forward CVEs, near-dup ≤3/template. |
| - Each record tags `metadata.grounding / license / provenance / has_think / is_negative / cvss_source / tool_output`. |
| |
| ## ⚠️ Use in production (read before training/deploying) |
| This set trains **reasoning and judgment**, not a fact oracle. To avoid hallucination: |
| 1. **RAG for facts** — CVSS is estimated, not authoritative; CVE recall is unreliable at ≤8B. Supply CVE/CVSS/version truth from NVD/GHSA at inference. |
| 2. **Real tools, never invented output** — `metadata.tool_output="simulated"` marks learned tool results; execute tools for real in production. |
| 3. **Human-in-the-loop on exploitation** — PoCs are drafts to verify in a sandbox. |
|
|
| ## License / provenance (IMPORTANT) |
| Mixed provenance, tagged per record in `metadata.license`: |
| - **`GPL-2.0-or-later`** (4,001, provenance=exploit-db) — the card license reflects this (most restrictive). |
| - **`review-upstream`** (4,773, h1/portswigger/web_offensive) — confirm each upstream source's terms before redistribution. |
| - **`synthetic-authored`** (643) — project-authored. |
| |
| For a **closed-source** product: training is generally permissible, but redistribution of GPL-derived data/weights can carry obligations — get legal review, or train a shippable model on the non-GPL (`provenance != exploit-db`) subset. |
