Oh hey folks.
Yes there has to do with Mine craft mods mainly.
This because Minecraft addons work via java and small bits of C Code that can be executed on a target machine. Because of this there has always been a risk downloading minecraft mods from the day they were avaliable.
World of warcraft addons meanwhile are sandboxed. They can’t access your file system or your network as the vital function calls in the Lua API that do this are removed from wow’s implementation of the Lua parser. It can’t affect them because to addons they don’t exist.
While there have been instances of Malicous addon code it usually doesn’t last very long as the vibrant Addon author community is pretty viligilant on that front. And in any case only afffects things in game and not outside it.
