Prosecutors said SBF’s usage of Signal is consistent with “a history” of using the software to conceal his activities at FTX. Bankman-Fried and former Alameda Research CEO Caroline Ellison were purportedly members of a covert “Wirefraud” group discussion on Signal before FTX’s downfall in November. SBF reportedly ordered workers to activate Signal’s vanishing messages function during his stint at the exchange.
