So what is it?

This repository claims to distribute XWorm 7.4, a tool labeled in its own topics as a Remote Access Trojan (RAT). A RAT is software that allows a remote operator to take control of another person's computer without the owner's knowledge or consent. XWorm is a documented piece of malware that has been used in attacks targeting Windows systems. The README is nearly empty. It contains a name, a brief description stating the software is "fully owned by kings from nightcore," a screenshot image, a note to download from the releases section, and a disclaimer to use at your own risk. No source code, no technical documentation, and no legitimate use case is described. Distributing or using RAT software to access systems without explicit authorization is illegal in most countries. This repository does not describe a security research project, a controlled testing environment, or any authorized defensive use context.
