Compromised Railway API key racks up $2,433 Together AI bill running DeepSeek and GLM

Developer shawmakesmagic got a $2,433.37 bill from Together AI: an API key from a dormant Railway project was compromised in the Railway hack and used to run DeepSeek and GLM inference.

The threaded discussion highlights a structural pain: developers now juggle 100+ services whose secrets are wired into dozens of others, so any upstream breach means manually auditing every key — and "rotate your keys" is useless for keys you forgot existed. Dormant agent-era API keys silently burning four-figure bills is the inverse of finding crypto dust in old wallets.
