FTX US general counsel Ryne Miller tweeted: "Statement from John Ray, Chief Restructuring Officer and CEO of FTX — Consistent with their obligations as Chapter 11 Debtors-in-Possession, FTX US and FTX [dot] com continue to make every effort to secure all assets, wherever located.

Among other things, we are in the process of removing trading and withdrawal functionality and moving as many digital assets as can be identified to a new cold wallet custodian. As widely reported, unauthorized access to certain assets has occurred.

An active fact review and mitigation exercise was initiated immediately in response. We have been in contact with, and are coordinating with law enforcement and relevant regulators."
