# Researchers spell out secrets from air-gapped computers via RAM radio signals

Researchers demonstrated a method to leak data from air-gapped computers by encoding secrets as radio signals emitted from RAM. The finding matters because air gaps are meant to isolate sensitive systems, and this side channel shows that isolation can be bypassed physically.
