To whom it may concern: ZeroTurnaround is hereby filing a copyright claim against one GitHub account account according to the format provided at https://help.github.com/articles/dmca-takedown . 1. (Infringed copyrighted work.) The infringed work is ZeroTurnaround's main product called JRebel ( http://zeroturnaround.com/software/jrebel/ ). The version corresponding to the cracked JRebel in the GitHub repository is JRebel 5.3.1. It can be downloaded from http://zeroturnaround.com/software/jrebel/download/thank-you/?file=jrebel-5.3.1-nosetup.zip. 2. (Infringing material.) The infringing material is located at https://github.com/ddatsh/jrebel . It contains two items: a cracked version of JRebel 5.3.1 binary (jrebel.jar) and a cracked license specially designed to work with the above-mentioned cracked JRebel. This effectively circumvents JRebel's internal copyright protection mechanisn that unlocks the product only to users that provide a valid license. This violates ZeroTurnaround's copyright and other rights in various ways - most obvious of them being the illegal/unauthorized modification and redistribution of a copyrighted work. 3. (Contact information.) For copyright-related matters, ZeroTurnaround can be contacted via e-mail address ip@zeroturnaround.com . The general contact address for any matters is support@zeroturnaround.com . Physical address : Roosikrantsi 11, 3rd fl / 10119 Tallinn / ESTONIA. All information available via http://zeroturnaround.com/ . 4. ZeroTurnaround is currently unaware of the contact address of the infringer. I have a good faith belief that use of the copyrighted materials described above on the infringing web pages is not authorized by the copyright owner, or its agent, or the law. I swear, under penalty of perjury, that the information in this notification is accurate and that I am the copyright owner, or am authorized to act on behalf of the owner, of an exclusive right that is allegedly infringed.
