craftsman | NET 7 scaffolding tool to help you stop | Continuous Deployment library

Let's say I have an app with many different entities, which do not have relations between each other.

I would like to create a search that queries all of them, but returns a unified type, i.e:

Which Roblox/LUAU classes can have malware/scripts hidden inside? Which classes will still be executed as a script? Which classes cannot contain a malicious script? Audio?

Since the complaint has been made that it's not clear what I'm asking, I've added emphasis above and put the title in there, too.

Ok, so I'm trying to learn how to detect and remove malware from things in the Roblox Studio Toolbox. That is a tall order, since I'm still learning LUAU and there are many ways to conceal malware, including obfuscation techniques (spacing, reversed strings, reversed ascii strings, getfenv(), hidden teleports, nested scripts, scripts that were reclassified to something else, like a weld, etc.).

Reclassified malware is the thing I have the most trouble with, although long scripts and scripts split into different files can be a pain, too. I do things by trial and error, like in the case of the Sakura Tree model by TreelingDeveloper (rbxassetid://6787294322). I stripped it of everything except the Trunk and Mesh, Falling Leaves and Particle Emitter, and Leaves and Mesh, and it is still similar, despite removing a couple dozen pieces, including two scripts that were nested inside several welds and claimed to weld the bark on.

Edit: I rechecked the Sakura tree after posting. Deleting all those parts reduced its visual appeal, although not completely. There were a lot of "Bark," "Other" and "Welds" that I deleted, and even the ThumbnailCamera. As it turns out, keeping all of the "Bark" and "Others" adds additional details to the trunk. I can't see a use for the ThumbnailCamera or the welds and "auto-weld" scripts.

It's not terribly hard to use CTRL-SHIFT-F to search for words like "getfenv," "string.reverse," "require," "eriuqer," and "teleport" but it is beyond my level of ability to find everything.

If you have any suggestions or tips on the question or the larger issues of malware in Roblox assets, I'd love to hear about it. Thanks!

Thus far, I have reviewed several (~10) plug-ins for detecting malware. None of them have seem to have behavioral or real-time detection. They all seem to use simplistic heuristic detection, often relying on common words and phrases associated with known malware, as well as certain LUAU commands and obfuscation techniques. Those that I thought were worth using, as inadequate as they were, are GameGuard, Guardian Angel Defender, Mirror Egg and Ro-Protect. Unfortunately, they get a fair number of false positives (Mirror Egg, for example, suggests that anything with the name "Fire," including fire effects I added, may be malware). GAD has the best UI and seems to find more than anything else, but it also finds a lot of "empty objects" that I'm not sure what to make of. None of them are real-time, and none are good enough on their own.

I'm not artistic, so it really isn't possible for me to develop my own models, meshes and such, and I think people who say those who use the toolbox are lazy and get what they deserve are apparently unaware that not everyone is a master craftsman when it comes to CG.

Roblox Studio's Toolbox is jam-packed with assets, which is great, except many of them contain malware.

Beyond this point is mostly a rant. Feel free to ignore, unless you're going to tell me to contact Roblox Customer Service or go to the Roblox DevForum.

You may ask why I don't post this on the DevForum. I've been there since April and, despite 7 hours of reading and over 1k likes, I still have not become a "regular". I asked customer service about this, but they gave me the run-around, referring me back to the rules to become a regular (which are deliberately vague) and generally being eager to get rid of me as fast as possible without actually helping.

You may ask why I didn't ask Roblox for help. Having asked both the Appeals team (which had given me a 3-day IP ban and permanently suspended my unlisted, >private< game that is still in development because, they stated, I'd added an "inappropriate model" from the toolbox - a model that I didn't modify, and then rejected my appeal without any valid reason) and Customer Service, which gave me the run-around and did their very best not to help me, and to get rid of me as rapidly as possible, I'm trying to learn how to protect myself. In short, Roblox apparently refuses to take any real steps to deal with the plethora of malware, and help pages DO NOTHING to teach developers how to find malware. I've learned more on my own - which isn't nearly enough.

If I sound irritated, it's because I am. They have some of the worst customer support I've ever encountered in the 36 years of my adult life, and I've got many years of experience in that field, including tech support.

The Roblox tutorial pages have this to say when it introduces the toolbox:

> Anyone can upload an item to the Toolbox, so make sure your game still works after adding an item before settling on it. To learn how to inspect a model before inserting it, see [Item Inspection][1].

The linked page is woefully inadequate, and the page that Customer Support referred me to is, too. [What Is This Infected Model On My Place? help article.][2]

I'm trying to scrape lowes.com product details and here's the script I'm trying to run

I have a query that returns the total number of users per a specific meta value (gender), considering only users that are not blocked (user_blocked_access):

There is a column (spot_categories_name) in the dataframe like the one below. My goal is to get rid of the 'name' at the beginning and the parenthesis (}]") at the end. Briefly, I want to edit the following

I am currently making a small, test website, and I have a function that will add an image to the innerHTML based on the input:

I hope you are fine.

I am using MaterializeCss to create a

I need to center it all, except the buttons, they need space between.

As long as I use full screen - everythink works fine. Here is my issue, my body container is our of control. I dont know why the content doesn't center...

I am currently working on an app that will connect clients and craftsmen. Right now I am structuring the database and thinking about possible queries. I noticed that it is not so easy to use the location-based aspect and I am right now struggling with this and my research didnt really help.
I am using Flutter & Firestore.
