Very real threats to your business

And the more agentic you are, the worse it becomes.

VIBE-CODED STARTUP · MAR 2026LINKEDIN ↗

$2,500 lost. 175 customers charged $500 each.

Anton built his startup with AI tools. Stripe was integrated, users were paying, everything looked fine. His API key was exposed in the frontend code. Someone found it. 175 of his customers were charged $500 each. He found out when the emails started coming in.

LOVABLE · MAY 2025SEMAFOR ↗

170 apps. Names, emails, payment data.

A researcher scanned 1,645 apps built with Lovable. 170 had critical security flaws. Names, home addresses, Stripe statuses, and API keys were readable by anyone who knew where to look. The apps were live. The founders didn't know.

STRIPE MARKETPLACE · FEB 2025REDDIT ↗

$41K gone in one hour. Stripe blamed the victim.

He had 2FA on. Secret keys in .env. Instant payouts disabled. Attackers still found a way in. Fake connected accounts, one hour, $41,000 gone to a debit card. Stripe sent a canned email. No funds were recovered.

They shipped with confidence.

Stripe is safe. Your backend isn't :/

Our developer moves fast, which is what I want. But the payments table was exposed and heading to production. Argus caught it before anyone saw it. Another week and that would have been live.

Founder @ Unify.FM

I had people paying me and genuinely didn't know if their data was open to anyone. My database key was exposed and user records were readable without logging in. If a competitor found that before I did it would have been over.

Tenant addresses, payment history, IDs. If any of that got out I'd be dealing with lawyers. I knew it in the back of my head but never actually checked. At least I found out from Argus and not from a breach.

A private pentester found it. We fixed it and looked for a solution that would catch stuff I don't.

I use AI to build everything and I'd be lying if I said I understood every line of what got generated. There's this nagging thing: okay but what did I actually ship. Argus is the senior engineer I don't have budget for.

CTO @ West Inc.

One junior dev, no security background. A deployment had made our customer orders publicly readable and we had no idea. We didn't notice, no one told us. Argus caught it. That was enough for me.

Thilo Thies

When someone books with me they hand over their home address and card. I never really checked if the backend was protecting any of that. Argus found three things in the first scan. Fixed them the same afternoon.
