During the history of ROBLOX, many exploits were found, disseminated, and abused by ROBLOX users. Most of those were, over the course of development, fixed by the ROBLOX developers. New exploits have formed, and a conspiracy suggests that Vault 8166 hackers may be linked to the creation of many exploits out there.

There is no solution to completely eliminate exploits on ROBLOX. However, many advances towards reducing exploiting have been attempted.

One most notable client, RC7 or RC7 Rewrite has been around for quite some time, mostly found on v3rmillion, a site for not only creative coding but one of the main places for exploiting. There is others like Intriga and such.

However, a client called Spare Reborn is becoming more popular each week, as old games like The Underground War by stickmasterluke are playgrounds for exploiters who have it, which forces some game creators to use FilteringEnabled or FE, a script that only exploiters can see their damage, but others can't and won't be affected by the damage. You cannot simply just insert the script, you need to do work with your game so it'll be the same.

Rumors have circulated on ROBLOX that suggest that the "hackers" who accessed John Doe's account in 2016 will return to ROBLOX on March 18, 2017 and "hack" all accounts that are logged in at that time. ROBLOX has addressed on previous occasions that it is impossible for someone to hack into a ROBLOX account; what is more likely to occur is an account being passguessed (due to the player having an easy-to-guess password) or their login information being shared on phishing websites.

A user that goes by 3dsboy08 have warned the exploiting community in v3rmillion forum about skidded exploits and roblox major update, known as "Judgement Day". During March and April, many skidded script executors have been released to the public for free, which means a bunch of kids is going around and running 666 scripts in most known FE disabled games or just ruining the servers. These exploits uses a method that can be easily created, but also easily patched. Here is what 3dsboy08 said in his thread:


April 19th, 2017 was ROBLOX's "judgement Day". Many exploits were patched, but some still work.

Lua bytecode

When Lua runs programs, the Lua virtual machine compiles code to Lua bytecode before it is interpreted. This process is irreversible without artifacts (via decompilation), and thus was frequently used for Code Obfuscation.

Lua bytecode does not have the same structure as Lua and allows, by unconventional means, manipulation of the stack and other things that are not possible in normal Lua programming. It is possible, though difficult, to write Lua assembly code manually and to assemble it into Lua bytecode. The ROBLOX process can load Lua code and Lua bytecode through use of its loadstring function.

It has been proposed on the Lua mailing list that direct stack manipulation could be used to access the environment of other functions during their execution and, therefore, to steal values from these functions (including C functions that Lua has access to), something which is not possible in pure Lua.

The ROBLOX user NecroBumpist proved the idea to be true and possible.[1] Using Lua bytecode, he created a function that allowed a script to steal values from other functions, including C functions. This made it possible to steal values from ROBLOX's API's, but months passed until someone found a way to use this bug to modify the global environment and to become capable to make the core scripts and the join script execute any Lua code in a game server.

This resulted in the removal of bytecode from ROBLOX and the ability to use it with the loadstring function.[2] Despite common belief, this exploit was unrelated to a Direct Dynamic Library (DLL) exploit in the same time period. The removal of bytecode had no other side effect than rendering code obfuscation impossible without other means.

DLL Injection

Most current exploits are DLL files that are injected into ROBLOX using a DLL injector or sometimes a creator made injector that injects for the exploiter when opened. Once injected some exploit give a command console or GUI that allows the exploiter to have admin abilities such as speed and jump hacking, teleporting, stat changing, and changing world properties while stronger exploits allow the player to execute Lua scripts to create aimbots and ESPs, get weapons normally unattainable in game, and morph themselves into other characters. DLL exploits can't be fixed but ROBLOX can patch the exploits (although exploit creators find ways around the patches and update their exploits).

Please note that lots of theories about hackers are not real.
