Apparently the Github organization title and logo was changed, along with a couple of packages edited to contain scripts that were supposed to erase all files on user computers. The Github repos are just backups of the main package archives, so it would only affect users manually downloading packages from there (which is not the case if you haven't explicitly changed your system config to use those repos for some reason).
