Researchers say deleted Google API keys can remain usable for up to 23 minutes, enabling Gemini data access and billing abuse

Security researchers found that Google API keys may keep working for up to 23 minutes after a user deletes them, leaving developers and organizations exposed during what they believe is a safe shutdown period. Aikido says revocation propagates unevenly across Google's infrastructure, allowing repeated authenticated requests to still succeed against some backend servers; if Gemini is enabled, attackers could access uploaded files and cached conversation context, and abuse automatic billing tier increases to run up large charges.
Why it matters: Anyone using Google APIs, especially Gemini, could still be exposed after deleting a leaked key. Treat key deletion alone as insufficient: rotate credentials quickly, restrict key permissions, watch for ongoing usage and billing spikes, and disable affected projects or services if abuse is underway.
