The digital rights management software for Amazon’s Kindle has been hacked. Kindle is a platform developed by Amazon for displaying e-books. The hack attack means that e-books stored on the reader can be transferred to other devices. DRM software is controversial. Rights holders see it as crucial to protecting their copyright material from illegal copying by users, whilst users find that it restricts them from the freedom to do what they want with content. The Kindle hack attack follows other recent DRM hacks, including the reverse engineering of Apple’s DRM software for its iTunes service.
