An executive in your company reports odd behavior on her PDA. After investigation you discover that a trusted device is actually copying data off the PDA. The executive tells you that the behavior…

PDA Hijacking is not a recognized standard attack classification and does not describe any specific Bluetooth-based data exfiltration mechanism.

Session hijacking involves taking over an active authenticated network session between two communicating parties, and has no connection to Bluetooth-based data theft.

Privilege escalation refers to gaining elevated system permissions beyond what was originally granted, which is unrelated to the Bluetooth data copying described in this scenario.

Bluesnarfing specifically involves unauthorized data theft from a Bluetooth-enabled device by exploiting the Bluetooth connection after an initial pairing or object-push interaction. The attacker tricks the victim into accepting a malicious e-business card (vCard over OBEX), which establishes a Bluetooth channel allowing the attacker's device to copy files and data off the target PDA. This matches the scenario precisely - data exfiltration began immediately after accepting an e-business card from an unknown person.
