Unverified50% confidenceFactExact time
The iOS kernel attack surface is relatively narrow and protected by the hardware Secure Enclave, and exploit chains for such vulnerabilities typically require combining multiple vulnerabilities, making the cost extremely high.

Unverified现代iOS越狱通常需要组合多个漏洞形成完整的利用链,包括用户态代码执行、内核信息泄露、内核代码执行及绕过硬件缓解措施77% similarUnverifiedThe iOS sandbox is implemented through kernel-level mandatory access control; even if an app is infected by malicious code, an attacker needs additional vulnerabilities to break through the sandbox boundary.74% similarUnverifiedVulnerabilities at the baseband level can often bypass multiple layers of operating system protection; in theory, attackers may be able to achieve remote intrusion without any user interaction.71% similarUnverifiediOS kernel vulnerabilities and privilege escalation refer to attackers exploiting memory corruption, logic flaws, and other issues in the iOS kernel (XNU) to escalate from ordinary app privileges to the highest system privileges (root).71% similarVerifiedSecure storage of API keys on iOS relies on Keychain Services, which is protected at the hardware level by the Secure Enclave coprocessor; the data is bound to the device and is not included in iCloud backups by default.69% similar
