CST VerdictBased on our analysis of available product data, here is our conclusion:
Damn Vulnerable iOS App (DVIA)
iOS penetration testers and security training programs need Damn Vulnerable iOS App because it's the only free, legal sandbox that replicates real native app vulnerabilities without the compliance risk of hacking actual apps. DVIA includes ten purposeful flaws across authentication, data storage, and crypto, making it the de facto lab environment for mobile red teams and offensive certifications. Skip this if your team is evaluating runtime protection or needs to test against obfuscated production code; DVIA is deliberately simplified for learning, not production-grade threat modeling.
Penetration testers and iOS security researchers targeting iPhone 5s through iPhone X need checkra1n for its semi-tethered access to A9-A11 chipsets via the unfixable checkm8 bootrom exploit, which remains unpatched across all iOS versions. The exploit persists because Apple cannot patch bootrom vulnerabilities in hardware already in the field, making checkra1n the only reliable jailbreak for these legacy devices in controlled testing environments. Skip this tool if your scope includes iPhone XS and newer; checkra1n's bootrom approach doesn't reach A12 and later chips, and you'll waste time on incompatible devices.
