just for my own curiosity, I assume when you say that you mean they can do a lot of things in game, but nothing outside. I've played the game for so many hours but never considered that a card I get from bepis might be able to infect my computer. I do think if it were the latter, something would have been said/done in aau to fix/prevent it, especially with how old the game is
well modules are built with a custom ineditor compiler with a very limited library of functions. i dont really think a virus can be written in to them.
MAYBE if they used the lua function call,
but that would require you also download and install a custom triggersuplimental.lua file from them
in any case, it remains an absolute fact that absolutely anything you download from the internet could have a virus in it. there can be viruses in Gifs. and viruses in pngs, and in word docs, and excel docs....
you dont even have to download anything, your browser can accidentally let malicious code through. ANY browser. i guarantee it.
if you live on earth, you might as well just accept the idea you are at risk of getting viruses every second of your life.
4chan went down recently, that was an exploit stuffed into a PDF file lmao
edit: note that cards are in fact .png files so technically someone could put a virus in the card without ever touching modules lol this world just sucks like that
