This is what hackers may do to hack HObfus [RACCOON]...

This is the intercept function for document.write.

const realw=document.write.__proto__.toString;
document.__proto__.__proto__.write=function __dummy__(str){
	printStr(str);
};


The following `fakeToString` will feed fake toString value
so it makes HObfus think that document.write is not
overridden.

function fakeToString(){
	let ret=Reflect.apply(target, thisArg, argumentsList);
	if(thisArg.name=="__dummy__"){
		ret="function write() { [native code] }";
	}else if(ret.indexOf("{ [native code] }")!=-1){
		ret="function "+thisArg.name+"() { [native code] }";
	}
	return ret;
};
const fts=fakeToString();
console.log("fts",fts);
return fts;


To countermeasure, implement `name proxy`
