NullPointerException

Paper exploit prevention against malformed packets

Installation

Installing and configuring the plugin is extremely simple, just follow the steps below:

Download and add the plugin to your server in the plugins folder, once installed
the server should be restarted to load the plugin. Once the plugin has run for
the first time you can then configure the plugin at plugins/NullPointerException/config.yml.

Alerts and Bypassing

By default, NPE will not alert staff members when a player is detected for a malformed packet, this is because
even when a malformed packet is detected, NPE may alter the packet to prevent the exploit from being executed.
However, this can easily be changed by running the command /npe alerts and toggling the alerts on for yourself.

To toggle bypass this plugin, you can run the command /npe bypass and toggle the bypass off (on by default
for staff) for yourself and get disconnected when a malformed packet is detected. Even in bypass mode, staff will
get flagged for malformed packets but no remediation will be done.
