How to hook a function by Address ?

[b00tkitism]

There is a class in System.Net named RemoteCertificateValidationCallback that's used for validating remote certificate, I hooked this class's constructor and it had an argument that contains the address of validator function, I want to hook that to always return true

already tried this for hooking the address and it didn't work:

system = Il2Cpp.domain.assembly("System");
system.image.classes.forEach((clazz) => {if (clazz.name.includes("RemoteCertificateValidationCallback")) {rcvc = clazz}});
m = rcvc.method(".ctor");
m.implementation = function(a, b) {
    Interceptor.attach(
        ptr(b.toString()), { 
            onLeave: function(ret){
                console.log(ret)
            }
        }
    );
    this.method(".ctor").invoke(a, b)
}

I think you want to do something like this;

const system = Il2Cpp.domain.assembly("System").image;
for (const klass of system.classes) {
	klass.fullName.includes("RemoteCertificateValidationCallback") {
		klass.method(".ctor").implementation = function(arg1, arg2) {
			console.log(`arg1: ${arg1}`)
			console.log(`arg2: ${arg2}`)

			arg2.class.method("idk").implementation = function(...args) {
				const orig = this.method("idk").invoke(...args);
				console.log(`idk: ${ret}`)
				return orig
			}

			const orig = this.method(".ctor").invoke(arg1, arg2);
		}
	}
}
