Correct me if I'm wrong, but doesn't cache.db store data you get from servers? (Ex. addons, music, textures) Assuming this is the case, couldn't someone just create an addon with a RAT in it, and disguise said RAT as a typical addon? It would then end up in the player's computer, and depending on how many players connect to aforementioned server (take for example a popular one like tezuni's), the host could create a botnet.
If this is possible, can it be fixed?
If it isn't possible, apologies for a stupid question.
