I take this claim with a pinch of salt. It's a neat idea: exploit IE to install a sniffer that picks up Gmail passwords etc. on the local network, but the only "ultra sophisticated" bit of this I can tell is that the hackers did a really good job of covering their tracks.<p>The article mentions that your average cybercriminal is lazy, and I can believe that - you're only going to put as much time in to an attack that you're going to get out in financial reward. But if a commercial hack was going to bring about the same financial-level of reward, I bet the cybercriminals wouldn't be sloppy.
