Sure, wallet theft is more akin to a heist and could net massive gains if you pick your target well. Is there any malware that actively looks for and steals wallets? I don't know, probably.
searching the web for
bitcoin stealing malware
returns a lot of results, some are from 2014.
Still, with a big enough bot net doing your mining and paying for the wattage i imagine it adds up. I wouldn't mind owning one :)
i am not sure mining on a botnet is the best way to profit from it. AFAIK, conventional CPUs are not efficient for mining, far worse from ASIC/FPGA?? or good video cards. probably the Internet Of Things will change this, allowing to install few ASIC miners to the rooted box.
Yeah it seems there is lots of both kinds, and other kinds too. An interesting summary: http://bravenewcoin.com/news/bitcoin-stealing-malware-evolves-again/ "A fourth type of bitcoin-thieving malware was recently created. This new variety hijacks the infected device's Windows clipboard, and replaces bitcoin addresses as they're copy and pasted. Trojan.Coinbitclip is the first instance of this new type of attack, discovered by Symantec on Feb 2nd. It was designed to watch for a bitcoin address copied using the clipboard, and replaces it with one of it's own, bypassing any protection from multi-signature and hardware wallets. While clipboard hijacking is not a new concept, this is the first time it has been found replacing bitcoin addresses." But yes of course you're right general purpose CPUs do not mine nearly as well as machines with dedicated mining ASICs. Stuff like the people in Venezuela use (where power is free, but everything else is unobtainable...).
It seems bitcoin is pretty resilient to other attacks on subtle features... although i'm not that well versed in the subject.
i am not familiar with bitcoin, but AFAIK it is something like "advanced socialism" by design. "consensus" of something like 50+% allows fucking up with coins and transactions and there already was a controversy about a "corporation of miners" abusing this unless i am mistaken.
