Howdja like some popular software on the cheap, and on the semi-down-low? Never mind what we might do behind the scenes. That was basically the value prop behind OSX.Trojan.iServices, which went live around the time of Macworld 2009, just as iWork '09 was formally introduced to the market. While the Trojan promised to deliver the Apple productivity suite for less money, it also installed a back door through which all kinds of malware could be introduced. A similar version was subsequently targeted at Adobe Photoshop. Neither exploit was all that successful in terms of the numbers of people who fell for the ploys, but somewhere north of 20,000 users were affected.
