Incident Overview
A Google Gemini user reported on Reddit that their development business, which normally spends about $180 per month on Gemini AI services, was hit with $82,314.44 in charges over a 48‑hour period after a stolen Gemini API key was used to generate large volumes of Gemini 3 Pro images and text. The user, known as RatonVaquero, deleted the compromised key, disabled the Gemini APIs, rotated credentials, enabled two‑factor authentication, locked down IAM, and opened a support case with Google. Initial feedback from a Google representative suggests the charges are likely to remain.
Contributing Factors
- Some Redditors argue that the API key may have been exposed due to recent changes in Google’s API key secrecy rules, which could have made the key easier to discover.
- The victim’s company lacks “basic guardrails for catastrophic usage anomalies,” such as automatic service freezes or per‑API spending caps.
Existing Google Guardrails
- Personal/Consumer Gemini customers are protected by flat monthly fees and usage caps.
- Developer/Business Google AI Studio users can configure Quotas to limit the number of requests per day or per minute.
- Google Cloud (Vertex AI) users can set Budget Alerts to receive notifications when spending reaches a predefined dollar amount.
Desired Safeguards
RatonVaquero and other developers are calling for additional protections, including:
- Temporary service freezes triggered by abnormal usage spikes, pending manual review.
- Per‑API spending caps that automatically stop further charges once a threshold is reached.
- More transparent budget and usage monitoring tools integrated directly into the Gemini console.
Next Steps
- The affected developer has filed a cybercrime report with the FBI.
- They plan to share detailed logs of the 455× usage spike with Google in hopes of receiving goodwill credits.
- Ongoing communication with a Google representative is expected to determine whether any remediation or credit can be applied.
