🚨 A quick security reminder about automation workflows
Don’t run workflows from strangers without inspecting every single node first.
Whether it’s an n8n workflow, Make scenario, Zap export, or a random JSON someone drops in a Discord or Skool post — blindly importing and running automations is risky.
There are bad actors out there. Some are obvious. Some are very good at hiding what they’re doing.
I’m sharing workflows to help people learn and move faster — but you should still verify everything before you run anything.
Why this matters
Automation tools usually have deep access to:
  • APIs
  • Databases
  • Credentials
  • File systems
  • Webhooks
  • Internal business data
A single hidden node can:
  • Exfiltrate credentials
  • Send your data to a third-party server
  • Create hidden webhooks
  • Write or delete database records
  • Trigger actions on a schedule you never notice
And the scariest part?
⚠️ It can look completely harmless at first glance.
Good security practices (please don’t skip these)
1️⃣ Inspect every node — no exceptions
  • Open each node
  • Check URLs, endpoints, headers, payloads
  • Look for unfamiliar domains or IPs
  • Be suspicious of “utility” or “helper” nodes
2️⃣ Verify the source
  • Who posted it?
  • Do they explain what it does and why?
  • Does the workflow come with context or documentation?
  • Anonymous drops = 🚩
3️⃣ Never import with credentials pre-attached
  • Remove all credentials before testing
  • Re-add your own manually
  • Never trust “ready-to-run” workflows with keys baked in
4️⃣ Test in a sandbox first
  • Use a dev instance
  • Use test APIs / fake data
  • Never run unknown workflows in production first
5️⃣ Watch for outbound traffic
  • HTTP Request nodes
  • Webhooks
  • “Logging” endpoints
  • Anything sending data “for analytics”
If you don’t recognize the destination — investigate.
6️⃣ Least-privilege access
  • Use limited API keys
  • Separate prod vs dev credentials
  • Rotate keys regularly
7️⃣ Assume automation = code
No-code does not mean low-risk.
Treat workflows like you’d treat a script from GitHub.
Extra red flags to watch for 🚩
  • Nodes with generic names like “Helper”, “Utils”, “Fix”, “Temp”
  • Obfuscated expressions
  • Base64-encoded payloads
  • Long inline JavaScript with no comments
  • “Just trust me” instructions
  • No explanation of side effects
Final thought
Automation is powerful — that’s exactly why it needs discipline.
Share workflows. Learn from others. Move fast.But verify first, always.
Security isn’t paranoia.
It’s professionalism.
