TL;DR: Akeyless’s October 2026 analysis shows that encrypted environment variables can still be decrypted if attackers compromise the systems authorized to read them, with up to 100,000 workspaces potentially affected. Encryption at rest is not a control boundary when the decryption path remains under someone else’s control, and that assumption now matters for every secrets programme.
Editorial analysis by NHI Mgmt Group, based on content published by Akeyless: “Railway Encrypted Its Customers’ Secrets but Attackers Decrypted Them Anyway”.
Key questions
Q: What breaks when encrypted secrets can still be decrypted by the platform that stores them?
A: Encryption protects stored data only until the decryption authority is compromised or misused.
Q: Why do static environment variables create so much risk for cloud and AI credentials?
A: Static variables persist across builds, deployments, and agent workflows, which gives attackers more time and more places to reuse a stolen secret.
Q: What are the signs that secret governance is failing in AI and workload environments?
A: The clearest signs are secrets that remain active outside their original workload, access paths that cannot be tied to a current owner, and role usage that appears only in telemetry, not in governance records.
Practitioner guidance
- Inventory every AI provider key and secret Map where each key lives, who owns it, and which services or agents depend on it, including environment variables, CI stores, and runtime configs.
- Challenge every vendor on decryption authority Obtain a written answer to whether the provider can independently decrypt customer secrets, and record that answer in your risk register.
- Convert high-value static credentials first Move the most sensitive database, cloud, and AI credentials to short-lived or just-in-time access where the target systems support it.
Bottom line: The breach shows that encryption at rest does not prevent exposure when the platform can still decrypt secrets on behalf of customers.
