CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
Red teams executing multi-platform campaigns will value CrossC2 for doing one thing exceptionally well: extending Cobalt Strike's command-and-control infrastructure to Linux and macOS without rebuilding your entire operational toolkit. The 2,546 GitHub stars and active maintenance signal a tool that actually works in production red team environments, not just in labs. Skip this if your operations are Windows-only or if you need post-exploitation capabilities beyond payload delivery; CrossC2 is strictly a C2 extender, not a replacement framework.
