Bug-bounty platform intelligence
When it applies
You're operating inside a platform's program. The technical work is the same everywhere, but scope enforcement, disclosure, payout, and reputation mechanics differ — and getting them wrong loses bounties or violates the rules.
Why it works
Each platform encodes its own contract. Reading the program's policy through the lens of that platform's conventions tells you what's actually in scope, what proof triage expects, and how your report will be judged — before you spend effort.
Key points per platform
- Common to all: the program's policy page is authoritative — read scope, out-of-scope, accepted vuln types, testing rules (rate limits, no-DoS, test accounts), and safe-harbor terms before touching anything. VDP (no bounty) vs paid changes your time investment.
- HackerOne: reputation/signal/impact affect invitations; structured severity (CVSS); private programs reward good signal. Watch the "eligible for bounty" vs "known issue" distinctions.
- Bugcrowd: uses the VRT (Vulnerability Rating Taxonomy) — map your finding to it and expect payout by the program's reward range for that VRT entry.
- Intigriti: clear in-scope/out-of-scope tiers; researcher-friendly triage; watch domain wildcards and the severity matrix.
- YesWeHack: EU-centric; strict scope; good for fresh European targets.
- Immunefi (web3): smart-contract/DeFi focus; payouts tied to funds at risk (often huge);
PoC on a fork/testnet, never mainnet exploitation; primacy/known-issue rules are strict. Pair with
code-review-solidity.
Method
- Read the policy end-to-end; extract scope, out-of-scope, rules, safe harbor, and the severity/ reward model.
- Set up isolated test accounts and honour rate limits.
- Rate your finding by the platform's model (CVSS or VRT) — see
reporting-cvss-scoring. - Submit per the platform's report format (
reporting-bug-bounty-writeup) and engage triage professionally (reporting-triage-communication).
Gotchas
- Out-of-scope is as important as in-scope — testing an excluded asset can void safe harbor.
- "Wildcard" scope still excludes third-party/SaaS you don't control — check.
- Platform reputation is durable; a spammy or rule-breaking submission history follows you.
