I messaged the offending plugin's devs on Discord. The creator of Tweakin says that the trojan detection in his plugin might be related to this issue, LuckPerms staff says that their libraries detections are either false positives or another plugin infecting LP libs and IV dev hasn't responded yet.

Project mention: Help with Minecraft RAT decryption (idk where else to ask for help) | /r/technicalminecraft | 2023-06-07

This is a RAT some1 tried to send me, could some1 reverse engineer to what discord webhook this is being sent to? I know for a fact that this is a discord webhook and I also know what obfuscator is being used (https://github.com/skidfuscatordev/skidfuscator-java-obfuscator/ this is the github link). Even more helpful would be if some1 could teach me how to deobfuscate things cuz Im kind of a noob. The link to the whole Jar file is https://drive.google.com/file/d/1WGvYfHeEYStsPmygwnGlCmnNyVAoB533/view?usp=sharing *Keep in mind this is a Trojan* The webhook is normally entered in the json.JSONrareException class. Any help is appreciated thanks! I tried looking at the decompiled code but again it is obfuscated and idk how to deobfuscate so plz help ty. If you dont want to download and decompile the rat yourself (thats totally understandable) I have inserted where I think are the important stuff here: https://pastebin.com/hEzDAdcg and the full code here: https://pastebin.com/aENGYHwn The variable I'm trying to decrypt is webthingy. It should be a link to a discord webhook.
