When an application is pirated, developers often do not know how bad the damage is. The nature of mobile app piracy is that those who perpetuate it do so in a way that makes it particularly challenging to track and evaluate whether they are losing business or merely attracting interest from early adopters. This issue came to a head again earlier this month when Hackulous, a longtime hub for piracy within the iOS community, abruptly announced it was discontinuing operations. Further, Hackulous was not merely an online discussion forum but a service that included its own app, Installous, that could transfer cracked apps to devices running iOS. It also maintained Apptrackr, a Web-based index of cracked apps. Experts say there will be plenty of others to take its place. Special Report
