[pmwiki-users] Security breach?

I've just found that there are also similar mystery php files in the
pub/skins/W directory - and this does not have 777 permissions.
And the extra link had been written to W.tmpl in that skins directory.
How could that happen? It certainly wasn't me, and I'm the only one who
knows the admin password! And the only one who has (legal) access to the
unix directories on the host.
