  1. """MalwareBazaar (abuse.ch) daily sample collector — PROBE/BLOCKED until reachable.
  3. Primary: daily JSON blob
  4. https://mbexport.blob.core.windows.net/malwaredata/<YYYY-MM-DD>_malwarebazaar.json
  5. Fallback: API v1 `get-recent` (abuse.ch auth-key required since 2023;
  6. free key from https://auth.abuse.ch/ — set env var, never commit).
  7. As of 2026-09-24 both endpoints are unreachable from this host's egress
  8. proxy (HTTP 502 on blob + API, retried). Collector records the probe and
  9. raises MissingCredential-style error so the runner records BLOCKED rather
  10. than silently skipping.
