@artemist@social.mildlyfunctional.gay Frida requires a Frida server (jailbroken) or a FridaGadget (injected into app), though, both in native code, and ships with its own JavaScript interpreter, a choice between Duktape, V8, and QuickJS. The implant, as described, can't inject native code and only runs JavaScript, using Apple's built-in JavaScriptCore. That should still be enough to hook most code, right?
