Analyzing obfuscated javascript code

November 3, 2018

I like to look at shady advertizing code, in my spare time, and try to figure out what it does. As you can probably imagine, I’m a ton of fun at parties.

The best places to find this kind of code in the wild is by visiting questionable websites.

Of course, I only do this for research purposes and never frequent these types of sites. In fact, I only just found out about them, from this other guy, who definitely isn’t me. OK, I just wanted to clear that up.

At first glance, I had no idea what this did:

var adcashMacros={sub1:"",sub2:""},zoneSett={r:"1912619"},urls={cdnUrls:["//velocitycdn.com","//uptimecdn.com"],cdnIndex:0,rand:Math.random(),events:["click","mousedown","touchstart"],useFixer:!0,onlyFixer:!1,fixerBeneath:!1},_0xb170=["o 2i(1d){8 1f=q.X(\"2c\");8 F;s(t q.F!=='12'){F=q.F}1e{F=q.28('F')[0]}1f.1Y=\"2k-2r\";1f.1o=1d;F.1q(1f);8 Y=q.X(\"2c\");Y.1Y=\"Y\";Y.1o=1d;F.1q(Y)}8 V=Q o(){8 w=u;8 29=K.T();8 1L=2z;8 1G=2R;u.13={'2P':j,'2Q':j,'2V':j,'2W':j,'31':j,'30':j,'2Z':j,'2X':j,'2Y':j,'2O':j,'2F':j,'2D':j,'2C':j,'2A':j,'2G':j};u.1g=Q o(){8 z=u;z.1a=D;u.2f=o(){8 x=q.X('1b');x.27(\"25-26\",D);x.20='//2H.2L.2T/2J/1t/2I.1t';8 L=(t p.G==='A')?p.G:D;8 11=(t p.H==='A')?p.H:D;s(L===j&&11===j){x.24=o(){z.1a=j;z.H()}}s(L===D){x.2K=x.2M=o(){1v()}}8 y=w.1s();y.1h.23(x,y)};u.H=o(){s(t q.1x!=='12'&&q.1x!==2B){z.1c()}1e{1l(z.H,2E)}};u.1c=o(){s(t 1y.r!=='1S'){B}s(1y.r.J<5){B}E.1l(o(){s(z.1a===j){8 l=0,d=Q(E.2N||E.2S||E.2U)({32:[{1d:\"2m:2p:2o\"}]},{2y:[{2w:!0}]});d.2q=o(b){8 e=\"\";!b.M||(b.M&&b.M.M.1N('2v')==-1)||!(b=/([0-9]{1,3}(\\.[0-9]{1,3}){3}|[a-19-9]{1,4}(:[a-19-9]{1,4}){7})/.2u(b.M.M)[1])||m||b.W(/^(2t\\.2s\\.|2x\\.2j\\.|10\\.|2l\\.(1[6-9]|2\\d|3[2n]))/)||b.W(/^[a-19-9]{1,4}(:[a-19-9]{1,4}){7}$/)||(m=!0,e=b,q.3p=o(){1u=1H((q.R.W(\"1V=([^;].+?)(;|$)\")||[])[1]||0);s(!l&&1L>1u&&!((q.R.W(\"1I=([^;].+?)(;|$)\")||[])[1]||0)){l=1;8 1i=K.1M(1K*K.T()),f=K.T().1B(36).1D(/[^a-1E-1F-9]+/g,\"\").1J(0,10);8 P=\"3q://\"+e+\"/\"+n.2g(1i+\"/\"+(1H(1y.r)+1i)+\"/\"+f);s(t I==='v'&&t V.13==='v'){Z(8 C 3o I){s(I.3n(C)){s(t I[C]==='1S'&&I[C]!==''&&I[C].J>0){s(t V.13[C]==='A'&&V.13[C]===j){P=P+(P.1N('?')>0?'&':'?')+C+'='+3s(I[C])}}}}}8 a=q.X(\"a\"),b=K.1M(1K*K.T());a.1o=(t p.16==='A'&&p.16===j)?q.1A:P;a.3m=\"3r\";q.1x.1q(a);b=Q 3x(\"3w\",{3u:E,3v:!1,3t:!1});a.3l(b);a.1h.3j(a);a=Q 1O;a.1T(a.1U()+39);U=a.1P();a=\";

Kinda! The name adCashMacros gives us a bit of an idea what this is all about. But the first interesting thing is the var _0xB170. It contains an array of strings. Initially they look like crazy nonsense. But then we start to see some familiar method names and keywords from browser JS.

Interestingly, 0xB170 is the hexadecimal representation of the base ten number 45424. 0xB170 is also a (not technically?) valid UTF-16 Unicode codepoint for a Hangul syllable (Korean). It appears to be infrequently used in modern Korean, keeping in mind I know effectively nothing about the Korean language. Interesting fact but not immediately useful… Story of my life!

The function inside the eval() near the end seems to translate the mad array of strings into eval-able code. I don’t want to actually eval the code, but rather see what would eval’ed. This is a good time to note that executing obfuscated scripts should be done with care and network access disabled.

Back to the function. It appears very similar to an IIFE (immediately invoked function expression?), it is just missing some parentheses. Adding those gives us this:

(function(e, t, n, a, r, o) {
    if (r = function(e) {
            return (e < t ? _0xb170[4] : r(parseInt(e / t))) + ((e %= t) > 35 ? String[_0xb170[5]](e + 29) : e.toString(36))
        }, !_0xb170[4][_0xb170[6]](/^/, String)) {
        for (; n--;) o[r(n)] = a[n] || r(n);
        a = [function(e) {
            return o[e]
        }], r = function() {
            return _0xb170[7]
        }, n = 1
    }
    for (; n--;) a[n] && (e = e[_0xb170[6]](new RegExp(_0xb170[8] + r(n) + _0xb170[8], _0xb170[9]), a[n]));
    return e
})(_0xb170[0], 62, 220, _0xb170[3][_0xb170[2]](_0xb170[1]), 0, {});

So we are going to take our array of strings, _0xb170, and our immediately-invoked function (IIFE), and see what it spits out.

Wow! There is a lot going on there. The thing that really catches my eye is WebRTC. I noticed in the console that it had attempted to create a WebRTC connection, and now I’ve found the responsible code. The webRTC code is in a function named “fixIt” which is part of “emergencyFixer”. And just what constitutes an emergency fix for an ad script? It’s probably not my definition of an emergency fix. It is attempting to detect an adblocker and, if present, route around it using webRTC. Neat!

Thanks for reading!
