Full detail
What changed
Removed the unsupported claim that environment variables were 'decrypted' and removed any explicit statement of an October 21 attack date in the summary. Retained facts explicitly present in the sources: Railway reports about 100,000 affected workspaces and independent reporting cites approximately $740,000 in fraudulent AI usage tied to stolen authentication secrets.
What is genuinely new
Railway’s incident report and independent reporting quantify the exposure as about 100,000 workspaces and attribute approximately $740,000 in fraudulent AI usage to the breach.
Detailed analysis
Railway’s incident report includes a numeric statement that the exposure represents about 100,000 workspaces. Independent reporting states that attackers stole customer authentication secrets and attributes approximately $740,000 in fraudulent AI usage to the breach while also citing up-to-100,000 affected workspaces. The available sources do not explicitly state that environment variables were 'decrypted' or provide a confirmed date of the initial intrusion in the provided excerpts, so the alert language uses the phrasing 'stolen authentication secrets' and omits a specific attack date.
