Yes, /etc/shadow would have always been readable only by root by
default. The interesting question here is whether an intruder did
it, clumsily leaving evidence behind, or whether it is just a local
change from following some bad advice about things that need to be
changed - or running some script to make those changes. The latter
seems more likely to me.
