The Day AWS Credits Vanished: A Startup’s 5-Figure Mistake (and How We Fixed It)

This is a true story.​

A small startup. One part-time dev in the US. One contractor abroad.​

They bring us in for something simple: just help them clean up their project management flow. A small engagement. Low stakes.

First day on the job, the client is panicking.

They’ve just received a massive AWS bill. Thousands of dollars. Gone.​

Someone had gotten unauthorized access to privileged AWS keys. But this wasn’t a data breach.​

The attacker was spinning up compute resources for crypto mining, and they burned through the company’s AWS credits fast.​

The worst part?​Those credits were supposed to cover their entire infrastructure for months. Suddenly, that runway vanished.​

No one on the team had dealt with a breach before. In a panic, they shut everything down, hoping to stop the bleeding.​

They needed more than project management. They needed a rescue plan. Fast.​Here’s the exact playbook we ran:

Our Remediation Playbook​

Worked directly with AWS support to investigate the attack and push for credit recovery (good news: AWS is usually great in cases like this).​

Enabled AWS Organizations to isolate environments and reduce the blast radius in the future.​

Rotated all credentials and API keys immediately.​

Hunted down the leak: were credentials hardcoded in the frontend? Pushed to a public repo?​

Implemented IAM roles with strict, least-privilege policies.​

Enabled logging and monitoring tools to catch future threats.​

Activated encryption at rest for key data services.​

Wrote Infrastructure as Code templates. No more risky clicking around in the Console. ​

This became the foundation of their CI/CD pipeline.

Reviewed costs and optimized services to avoid overspending again.​

Delivered a full report with findings, actions taken, and security guidelines for their devs going forward.​

All of this… for a 4-figure investment.​
Less than what they lost in credits.

​Way less than the stress and chaos it caused.​
Delivered in about two weeks.​

Don’t wait for the breach.​
Don’t wait for the billing alert.​

Hardening your infrastructure isn’t just for big companies. It’s for anyone who can’t afford to lose their product, their momentum, or their mind.
