Wanted categories
General
Who should hunt here
Beginners
Workable- Wide attack surface — 43 assets means overlooked corners (old subdomains, staging hosts) are statistically likely.
- Fast feedback — triage lands in ~1 day, so you learn what this team pays for quickly.
- Low entry point — the bounty floor starts at $50, so lower-severity findings are still worth submitting.
Intermediate
Good target- Real ceilings — payouts reach $8.0k, so chaining two medium findings into one report actually pays.
- APIs are in scope — where medium hunters get paid: broken object-level authorization, mass assignment, and rate-limit gaps.
- Active program — ~35 valid reports/month means the triage queue is alive and templates are established.
- Moderate crowding: enough competition that obvious finds go fast, but systematic work on less-visited assets still pays.
Pros
High value- $8.0k ceiling — worth deep recon and targeted fuzzing; one critical here outearns a month of small programs.
- 43 assets scale well with automation — attack-surface monitoring and diffing pay off at this size.
Think twice if
- Program age is unknown — YesWeHack doesn't expose start dates, so "freshness" can't be verified.
