Block Malicious URL Entry

Block the destination hostname, not zws.im. Production defaults to Railway environment production, service API.

Procedure

  1. Provide the known hostname, destination URL, or zws.im short URL. Stop if the hostname is ambiguous or belongs to a shared platform.
  2. Run railway status and confirm project zws, environment production, and service API.
  3. From apps/api, run railway run --service API --environment production -- node scripts/block-malicious-url.ts --dry-run --hostname '<hostname>' (or pass --url/--target-url). Review the resolved hostname and whether it is already blocked.
  4. After approval, repeat with --apply. The script inserts the hostname, refreshes Redis, and verifies the supplied short URL when --url is used.

The script intentionally does not bulk-update urls.blocked: retrieval checks the hostname block and lazily marks each matching row. Never print connection strings, credentials, or full environment output. Confirm the resolved hostname before applying.
