My app just hit Hacker News / Product Hunt — am I about to get breached?

Updated

Virality is the moment attackers wait for. Here's your 24-hour defense playbook.

Your Show HN just hit the front page. Your usage is 100x yesterday. You're excited. You're also realizing that every attacker reads Hacker News too. You have no idea if your app can handle what's coming.

What happens next

  1. Hour 0-1 — traffic surge

    Legitimate users flood in. Every bug surfaces — performance, error states, edge cases.

  2. Hour 1-6 — probing begins

    Security researchers (white, grey, black hat) probe your endpoints. Common tests: authentication bypass, SQL injection, open S3 buckets, leaked API keys in JS bundle.

  3. Hour 6-24 — exploitation attempts

    Anything found in probing gets tried. If your API allows unlimited inference requests, attackers drain it. If your RLS is misconfigured, they exfiltrate the data.

Without Securie

You monitor the HN thread praying nobody notices anything bad. You triage issues reactively. You hope for the best.

With Securie

You already ran Securie before launch. You've already fixed the common bugs. The HN traffic is just users; attackers find nothing to exploit.

Exactly what to do right now

  1. Run securityheaders.com on your deployed URL
  2. Enable rate limiting on every paid-API endpoint
  3. Set per-day spend caps on OpenAI / Anthropic / Stripe
  4. Verify Supabase RLS manually in Studio → Authentication → Policies
  5. Enable monitoring — Sentry or similar
  6. Request Securie access at /scan so the repo is reviewed before the launch spike
  7. Have an incident response plan before you need it
