FTX CTO Gary Wang as well has a lot of recent GitHub commit activity in last 2 days and now suddenly the site is hacked https://github.com/garywang
How do you know that? It says explicitly: "52 contributions in private repositories" between November 1 and November 11.
What's interesting is that a lot of the FTX people on the about page (https://about.ftx.com/), including Gary Wang and Dan Friedberg have deleted their LinkedIn accounts, whereas they were available earlier. If they're deleting something so harmless, then who knows what else they are deleting and covering up.
