What is a level 7 Roblox exploit?

It's pretty easy to google it. Levels are the Roblox Thread Identity that the script executed through the Roblox exploit is running. Normal LocalScripts run with Level 2, Roblox Scripts usually run with Level 3–4, the Command Bar on Roblox Studio runs with Level 5, and Plugins in Studio run in level 6. It is a common misconception that levels assosciate with how well an exploit is, but in reality, if you could already execute in Roblox, you could set the level. Most exploits run their scripts in Level 6 and intentionally downgrade their levels when calling certain functions in-game to avoid detection. Level 7 is an upper level that is suspected of being fake and a scam though probably existed with exploits like Synapse X before Filtering Enabled (FE).

As guild said, Level 7 probably existed back before Filtering Enabled, since then if I remember you could do almost everything, like even "hack" a Roblox game.

Allow me to explain how "Levels" work, and what they are.

"Level" in this case would be the Permission Level (Remember this)

So, let me explain, this is simplified, but, every script you'd have has it's own thread (you can see the threads by doing getallthreads()). Every thread for a script, function or argument has a security context level (or "level" as we call it). We can see the identity of a thread by doing getthreadidentity(). Remember that every thread has a security context level.

So, these "levels" exist, but what do they mean?

Well, "Levels" are classed from 1 - 8. Ironically, it's not always lowest class to highest class.

So, let's start off with what permissions exist:

None - Any identity can access this feature, including in-game scripts.

Plugin - Second-lowest access level, just above in-game script.

RobloxPlace - Places created by Roblox, where scripts are more trusted and preliminary features are allowed.

LocalUser - Non-game permission, usually for Roblox Studio.

WritePlayer - Permissions for changing player name, user ID etc. (Remember This)

RobloxScript - A script that is ran in a game. E.g: CoreScript

ROBLOX - The highest level of permission.

TestLocalUser - In test builds, this permission is equivalent to none, however, in non-test builds, this permission is equivalent to LocalUser.

Now, let's get to security context levels;

"Level" 0 - No Permissions

"Level" 1 - Plugin, RobloxPlace, LocalUser

"Level" 2 - None

"Level" 3 - RobloxPlace

"Level" 4 - Plugin, RobloxPlace, LocalUser, RobloxScript

"Level" 5 - Same as 1

"Level" 6 (Roblox Studio) - Plugin

"Level" 6 (RobloxPlayerBeta) - All Permissions

"Level" 7 - All Permissions

"Level" 8 - Same as level 1

So, those exploits that claim they are "LEVEL 8" and "BEST EXPLOIT" are really worse than any other level 6 or 7 exploit.

Lesson: Do some research and reverse engineering.

- Virtualization 

theres no level 7 exploits now since roblox has patched level 7 exploits
