Jailbreak
Removes the protective seal and any OS-specific restrictions to give users greater control over the device.
The Explain card
- Plain English
- Jailbreaking removes the manufacturer's protective restrictions from a device, giving the user more control than the operating system intended. In AI, the word also describes coaxing a model past its safety rules.
- Example
- A user jailbreaks a company-issued iPhone to sideload apps. With the OS protections gone, the mobile AI assistant's local data store is no longer reliably isolated from malicious apps.
- Why it matters
- Jailbroken devices void the security assumptions your app depends on. Defenders detect jailbreak state, limit sensitive features on such devices, and treat model jailbreaks as a parallel risk.
- Hook
- Popping the lock also pops the safety net.
