According to BlockBeats, on October 5, WSJ reported that people familiar with the matter said that a few months before FTX collapsed, some of its US employees discovered the so-called "backdoor" on the platform, and Alameda Research allegedly used the "backdoor" to withdraw billions of dollars of customer funds from FTX. Employees who discovered the problem reported the situation to the senior management of their department, and some people said that the senior management discussed the issue with an assistant to FTX founder SBF. However, the problem has never been resolved. In the summer of 2022, senior team members who raised concerns about Alameda's special rights to FTX were fired. This "backdoor" played an important role in the case against SBF, who was tried in federal court in New York for alleged fraud and the trial began this week. The former head of FTX pleaded not guilty to all charges. Prosecutors allege that SBF stole funds from FTX customers by secretly ordering the programming of "special functions", including giving Alameda the ability to handle FTX's huge pool of funds. Court documents show that hidden deep in FTX’s code was a line that allowed Alameda to have up to $65 billion in liabilities on FTX.
