An anonymous reader quotes a report from the Australian Financial Review:
Members of the inner circle of power at collapsed cryptocurrency exchange FTX formed a chat group called "Wirefraud" and were using it to send secret information about operations in the lead up to the company's spectacular failure. On Monday (Tuesday AEDT) Mr Bankman-Fried denied being part of the chat saying, "If this is true then I wasn't a member of that inner circle (I'm quite sure it's just false; I have never heard of such a group). The news of the chat group heightens concerns about the prospect of wrongdoing by Mr Bankman-Fried and his colleagues. Last week, Mr Bankman-Fried said he no longer had access to many of his own private communications. He was scheduled to testify virtually before the House Financial Services Committee on the 13th, but was arrested by the Royal Bahamas Police Force the day before. That said, Forbes published a transcript of SBF's planned testimony, where he at no point admits fraudulent behavior and does not address the (multi-)billion dollar loans that helped contribute to the collapse.
Most recently, we learned that FTX's chief engineer made a secret change to the cryptocurrency exchange's software that allowed FTX to use client money.
