Railway breach leads to $740,000 in fraudulent AI charges
Attackers stole environment secrets from at most about 100,000 workspaces after two infrastructure flaws.
Cloud host Railway says attackers exploited two previously unknown flaws starting October 20, escaping build isolation and abusing a misconfigured trust relationship to decrypt customer environment variables. Stolen AI credentials produced about $740,000 in unauthorized usage; Railway is seeking provider refunds and will cover declined charges. Linked tokens for 1,852 users were reset. Attackers were removed October 21, the flaws were remediated, and Railway found no evidence of Git repository or database downloads.
Unconfirmed: The 100,000 figure is a maximum of potentially impacted workspaces, not confirmed thefts; the Black October link is Railway's assessment.
- Railway disclosed the incident on October 22 after a roughly 26-hour intrusion.
- About 100,000 workspaces is a maximum potentially impacted, not confirmed thefts.
- Attackers also queried cloud, database, and payment service credentials.
- Railway links the theft to Wiz's Black October campaign against AI platforms.
- Exposed GitHub OAuth tokens and AI agent keys belonging to 1,852 users were reset.
