This is a clever attack.
After gaining control of the coin-mining software, the malware replaces the wallet address the computer owner uses to collect newly minted currency with an address controlled by the attacker. From then on, the attacker receives all coins generated, and owners are none the wiser unless they take time to manually inspect their software configuration.
So far it hasn’t been very profitable, but it — or some later version — eventually will be.
