II. Goal of the project

1. Description

The anti-cheat aims to catch players using external help. The main feature of the anticheat is to give a suspicious percentage to every player. The anticheat will adapt its behaviour according to every player, and store the informations. If a gap is reached, the player that reached the gap could be send to admins, or even could be immediatly banned.

2. Releases

Releases are available in the Releases folder. Please check CHANGELOG.MD to get the informations about the updates.

3. Goals

The goal is to use N3RO Ghost client and N3RO BetterColors and to make them detected. Those are undetected on the biggest minecraft servers at the moment. These hacks were made by N3RO to understand and find what are the weakness of popular anticheats. (Those "hacks" have never been shared with malicious people). If you are not allowed to view the code of the hacks, please contat N3RO: nero98@sfr.fr. This is to prevent malicious people to use the hack at their advantage.
