Paradox Interactive AB is the publisher of the game Hearts of Iron 4 (HOI4) which comes with a number of DLC and the ability to play multiplayer online. The DLC can be included in multiplayer games as well. I'm [private] employed at Paradox Interactive with the task of looking after our intellectual property rights.

**Please provide a detailed description of the original copyrighted work that has allegedly been infringed. If possible, include a URL to where it is posted online.**

The respository circumvents our dlc checks in multiplayer, making it possible for the user to enable and play our DLC, regardless of them owning the DLC or not.

**Do you claim to have any technological measures in place to control access to your copyrighted content? Please see our <a href="https://docs.github.com/articles/guide-to-submitting-a-dmca-takedown-notice#complaints-about-anti-circumvention-technology">Complaints about Anti-Circumvention Technology</a> if you are unsure.**

Yes

**What technological measures do you have in place and how do they effectively control access to your copyrighted material?**

Hearts of Iron verifies which DLC the user rightfully owns through the platform backend (Steam, Microsoft Store) at startup and enables/disables some game features depending on this.

**How is the accused project designed to circumvent your technological protection measures?**

The code on this repository can be used to execute arbitrary code inside the game process and circumvent the results of the DLC ownership check.

This is effectively the source code of a "crack" made to circumvent copyright protection.

**<a href="https://docs.github.com/articles/dmca-takedown-policy#b-what-about-forks-or-whats-a-fork">Have you searched for any forks</a> of the allegedly infringing files or repositories? Each fork is a distinct repository and must be identified separately if you believe it is infringing and wish to have it taken down.**

We have not searched for forks at this point.

**Is the work licensed under an open source license?**

No

**What would be the best solution for the alleged infringement?**

Reported content must be removed

**Do you have the alleged infringer’s contact information? If so, please provide it.**

**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 have taken <a href="https://www.lumendatabase.org/topics/22">fair use</a> into consideration.**

**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.**

**I have read and understand GitHub's <a href="https://docs.github.com/articles/guide-to-submitting-a-dmca-takedown-notice/">Guide to Submitting a DMCA Takedown Notice</a>.**
