I don't know how FTX works (and I suppose it depends on the specifics of your bank/jurisdiction), but it is possible that FTX has permission to pull funds from users' linked bank accounts or cards to execute buy orders. Users need to make sure they revoke all access, if they haven't already when they went bankrupt.
Seems I was right, and FTX has started accessing users' bank accounts illegitimately:

I've the FTX tracking app I use to keep my portfolio in check. I hope the alleged malware doesn't affect it, anyway.
I wouldn't risk it. Uninstall the app and scan your phone for malware. In all likelihood it's not going to be functional going forward anyway.
the fact is that we will no longer trust centralized exchanges
Good. You were never supposed to trust them in the first place.
