Kind: security · Impact: high

## In brief

- Attackers exploited vulnerabilities in Railway's infrastructure in an attack on October 21 and stole customer authentication secrets and AI provider keys.
- The stolen AI provider keys were used for an estimated $740,000 in unauthorized AI usage charges.
- Railway says up to 100,000 workspaces could have exposed credentials, and it has promised to pay the charges itself if an AI provider will not refund them.

## Why it matters

Secrets stored on Railway, especially AI provider keys, may have been exposed and abused, so developers should check their AI usage and harden their CI/CD and OIDC setups.

## What to do

- Review build access in CI/CD pipelines
- Tighten OIDC trust configuration
- Consider using Harden-Runner to observe and restrict CI/CD runtime activity
