Don't miss the forest for the trees. If it wasn't skype, it'd be some other channel. The point here is that mining malware is a rather new and troubling phenomenon.

And of limited real value. A CPU only miner would yield about 10 MHash/s or less on standard hardware, and a malware/junkware loaded PC will do even less.

Isn't the total hash rate the sum of the hash rates of all infected machines (i.e: 10MH/s * 2000 infected machines = 20GH/s)?

Far less than that. My shiny quad core i7 gets 4MH, and I doubt most consumer desktop computers would manage that. You're probably looking at 0.5-2 at a maximum.

Malware Bitcoin-miners, hmm? I don't like Skype as a vector... what if you could put it in the browser instead? Which leads me to a less malware-y idea: write a JavaScript/Flash/similar component that mines bitcoins in a web browser. Put it on your site instead of ads. Has anyone beat me to it?

That'd be an interesting advertising alternative that could be good for both parties. In exchange for content, you give the website X CPU cycles (or GPU I guess). It could be built into the browser so that you'd have really efficient mining techniques. Clients (with beefier computers) could choose to give more cycles to their favorite sites.

I'm not sure if you could provide comparable amounts of revenue. I guess time-spent-on-site would be the most important factor. At the current cost and difficulty of Bitcoins, you'd need 1,000 concurrent users on average all day all running at 10mhps to just make $92 per day. 10mhps seems like it's asking a lot, it'd probably drain a lot of batteries.

I recently came across a very naive-looking sample of a pooled GPU-miner being distributed via a purported crack for a certain EA game.

It's ridiculously easy to implement GPU mining if you have any remote execution on a machine.

Wouldn't work. The right API calls aren't exposed. You would need something like webCL.

A long time ago I did some proof of concept work to do GPGPU operations in the browser with regular webGL, it kind of worked: http://learningwebgl.com/blog/?p=1828#comments I did look into using the same technique to implement bitcoin mining in glsl. My opinion is that it is possible, but not straight forward and probably not worth it, but still a pretty f'ing cool concept.

Not worth it? If you can make it efficient, you're a millionaire, considering current bitcoin prices. Make any decently popular website, and you have access to thousands of mining computers.

Yes, I think so, but it would probably be pointless by now, and many would notice.

A new market for malware opens. This is even better than spam.

Actually it is better, isn't it. If malware starts working to keep the bitcoin transaction network operational as opposed to spamming or stealing webbanking keys ... then it's actually doing something that's either neutral or useful. Useful if you like bitcoin. That'd be a great step forward. I doubt it's worth the effort though.

Shouldn't it also be more noticeable? Quiet spyware can go undetected, but something that's eating up loads of CPU cycles is less likely to do so. That's a good thing.
