Zero-Click Exploit

An exploit that compromises a target device without requiring any interaction from the victim, purely by exploiting a flaw in how the device processes incoming data. Zero-click exploits are especially prized, and expensive on exploit markets, because they leave the victim with no opportunity to avoid the attack.
