Gemini API key abuse before June 19 unrestricted-key changes caused $35K bill. Support case still open, need Google escalation

Posting again because I’m trying to reach someone from Google Cloud who can help escalate my billing/security review.

My normal Google Cloud usage was monthly $250 . On May 12 my Gemini usage spiked to about $35K+ in 3 hours. This was not normal usage.

Support has been silent since May 22 and now receiving Google Collections email.

This incident happened before Google’s June 19 changes around unrestricted Gemini API keys. Truffle research also discussed how older public Google API keys become usable against Gemini after the API was enabled.

My ask:

Can a Google Cloud representative please help route this to the right billing/security escalation team? I can provide my case number privately to a Google Cloud employee or mod.

I’m asking Google Cloud to review server-side logs for the May 12 incident window, including source IPs, user agents, request volume, model/token usage, and whether the pattern matches known API key abuse.

Has anyone here successfully gotten a Google Cloud billing/security escalation for Gemini API key abuse?

Gemini API usage Spike, $35K in 3 hours. API key compromised - abused.

I was checking the email and saw a google email from an hour ago, when i check my ai studio, saw 35K+ balance. Normal usage is $250 a month. How google can let anyone make a spending like this ? Later i checked and seem like i am the victim of a pretty common api abuse.

Incident happened 5/12/2026.
I already deleted all api keys, put spending cap.

Worst part is google support went silent since 5/22/2026, my account got restricted, because i didn't update the credit card information that month. So i still have a balance of $36K something.

Any idea what to do ?
Anyone got their balance fixed ?
