A Los Angeles based large financial company that deals with the emerging crypto-currency and token-based capital markets. We can't disclose the name of company according to NDA.
The company's CTO addressed our CTO & Cloud architect with an urgent issue on a Sunday at 11 p.m. Their platform was hacked, and their project hot-wallet was emptied into external Bitcoin wallets. The damage dealt was estimated at 1 000 000 USD. We were set the task to return the entire sum or at least a part of it.
The company's issue was resolved completely. Apart from returning the money, we increased the security of the project and signed a contract for 24/7 technical support with a demanding SLA.
