I followed this a bit on Reddit, from the original post. It really sucked that there was apparently no reaction from the EGG, until this got picked up by Igor's Lab (which I didn't know about).

The OP on Reddit wasn't even when EGG found out about this. According to a commenter, they were informed in their Discord, replaced the infected file, then did nothing for about two weeks.

It sucks, because I was thinking of getting one of their mice, but now I'm not so sure if I want to support them, if that's how they handle an issue like this.

Edit: Mentioned in the Igor's Lab article, that EGG just said in one of their Discord channels, they re-uploaded the file, but nothing about malware.
