BlockTower Capital's main hedge fund has been invaded by fraudsters and some funds have been depleted. The insider, who did not want to be named due to the sensitive nature of the information, said that the funds are still missing and the hacker has not been caught. However, the company has hired blockchain forensics analysts to determine how the funds were stolen and recently notified its limited partners of the theft. When Bloomberg contacted BlockTower, they refused to comment on the hack.
