Railway urges every user to rotate keys after customer-secret breach
Developer platform Railway says hackers may have accessed encrypted environment variables and decrypted secrets for some customers, prompting it to tell all users to revoke and rotate API and cloud keys. The company paused deployments while investigating, temporarily freezing customer applications. Railway said its initial assessment indicated a subset of users was affected but did not disclose the number, root cause or compromised systems. It also linked the incident to a broader campaign targeting platforms that support AI inference.
