My Azure startup account had about $10k in promotional credits. While I was in the hospital, I received unexpected OTP emails(but I igroned them). I later found roughly $550,000 (₹5 crore) in Azure charges, apparently from unauthorized Claude AI usage through Azure Marketplace over about 9–13 days. There was claude usage from azure marketplace. I had a debit card attached on my azure account. I am just a college student, I think I had a minor heart attack yesterday. I didn’t create these workloads or authorize the usage. I’ve disabled resources and contacted Azure Support, but I’m worried about being held responsible for an amount I cannot pay. The Azure support person said there is no fradulant activity detected in the account. Has anyone dealt with unauthorized Azure charges this large?
