Thanks for the heads up! Quite plausible! Braintree support seems to respond very slowly. I will write to them again about this and the pending subscriptions.

Thanks for the heads up! Quite plausible! Braintree support seems to respond very slowly. I will write to them again about this and the pending subscriptions. Update: Called the Braintree support just now and verified it is infact a fraud (credit card attack). Unfortunately, there were 8000+ transactions by the end of the day and 1000+ transactions went through. I have configured risk threshold to avoid this in future. Now, I will have to refund and cancel each of these subscriptions. Damn fraudsters!
