Platform-as-a-Service provider Railway disclosed a security incident involving unauthorized access to customer environment variables, which store sensitive data such as API keys and database credentials. The company determined that an unidentified third party may have accessed encrypted environment variables and potentially obtained decrypted contents affecting a subset of users. Railway indicated the breach is likely part of coordinated attacks targeting platform companies with the aim of compromising artificial intelligence inference providers. The company has notified upstream providers to revoke affected keys and is recommending customers rotate their environment variables and review service logs for suspicious activity.
Security researchers noted that attackers exploited the breach to drain cryptocurrency wallets containing private keys stored on Railway, with the first known theft occurring hours before the incident was publicly disclosed. In response, Railway rotated bucket credentials, invalidated API tokens, and restored builds for certain workspace tiers. The incident reflects a broader trend of threat actors conducting “LLMjacking” operations, gaining unauthorized access to cloud environments to run artificial intelligence workloads at the victim’s expense while concealing their activities.
