Proximity Operations - EXF-0005

A nearby vehicle serves as the collection platform for unintended emissions and other proximate signals, effectively a mobile TEMPEST/EMSEC sensor. From close range, the adversary measures near-field RF, conducted/structure-borne emissions, optical/IR signatures, or leaked crosslink traffic correlated with on-board activity, then decodes or models those signals to recover information (keys, tables, procedure execution, payload content). Proximity also enables directional gain and repeated sampling passes, turning weak side channels into usable exfiltration without engaging the victim’s logical interfaces.
