New details about a hack from last month show that tens of thousands of users happily gambling away on DraftKings may have had their personal information stolen thanks to account info purchased off the sports gambling site.In a letter dated Dec. 16 that was apparently sent to users that was first-reported by BleepingComputer, the company said 67,995 people had their personal details exposed to hackers in a breach, adding to the financial hit some select accounts experienced in a brute-force hacking attack last month.Last month, users vented their frustrations with the company after they saw their accounts being stripped of funds while being locked out of their accounts, according to reports from the time.That initial breach back in November saw less than $300,000 drained from user accounts, according to the company.DraftKings co-founder Pauler Liberman previously said in a statement they were making any affected customers whole."
