CST VerdictBased on our analysis of available product data, here is our conclusion:
Penetration testers running red team engagements on tight budgets should reach for Social-Engineer Toolkit first; it's the fastest way to spin up custom phishing and credential harvesting attacks without writing payloads from scratch. The 12,355 GitHub stars reflect actual adoption among practitioners, and the framework's modularity lets you chain attacks that most commercial tools won't support. Skip this if your team needs post-exploitation stability or operator-friendly logging; SET is a craftsperson's tool that rewards scripting skill and tolerates rough edges.
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.
