Backdoors

Backdoors on 2b2t can refer to server backdoors or player backdoors. A server backdoor is when a player or group of players bypass the server's normal operations to gain access to exploits in which the particular players can abuse. There have been three major backdoors in 2b2t's history, all of which have been patched by Hausemaster. Player backdoors are more common and usually occur with player-made hacked clients, which give developers access to users' data.

First Backdoor
The first major backdoor of 2b2t had two intervals. The first interval of the backdoor began sometime in December of 2011 and ended in January of 2012. Popbob, during this first interval of the backdoor, had permissions to use the "TooManyItems" mod, which he gave to many Facepunchers, including xcc2, policemike55, and others. This access to TooManyItems mode and the backdoor allowed for the creation of Ziggy Town's bedrock comet and Plugin Town. Hause eventually ended this backdoor interval by removing popbob's access to some of his powers and permissions. Popbob also used his backdoor access to create hacked items. Eventually, the backdoor was patched by Hausemaster, disabling thunder from 2b2t for more than five years in the process.

Second Backdoor
The second major backdoor of 2b2t occurred during December of 2013. The backdoor involved iTristan and Pyrobyte designing a plugin to block access to the nether roof. The backdoor has two major features, the ability to spawn hacked items such as player heads and 32K weapons, and allowed travel on the nether roof if the player was riding a horse. They also used it to get to the world border.

Third Backdoor
The third major backdoor was the most severe backdoor to this date and occurred sometime during the end of 2015 and ended in April 2016. The backdoor involved Tristan creating a website backdoor to create illegal items and georgebush420 (operator - full perms) helping the Tyranny in their acts. The Tyranny used George to grief bases, and create more hacked items. The backdoor was patched before June 1st. Players either migrated to Constantiam or left the server temporarily during this time to avoid their base getting griefed/compromised. The server would have as little as one or no players online during this time, however this lack of players would only only last a short span of time. The active population had returned to its normal levels before the video by TheCampingRusher, and subsequently the 4th Incursion.

Cause of server backdoors
The first two backdoors were caused by Hausemaster using player designed plugins to fix issues on the server. These players would add in code to give themselves access to a backdoor of the server once Hause implemented the plugin. In the case of the third major backdoor, the Tyranny, the group befriended georgebush420.
