But what file transfer mechanism was used?  NFS maybe?

Certainly a simple NFS mount of an untrusted machine is a dangerous thing to do, since setuids on those files will be obeyed.  Maybe you allow this via an incautious AMD map?

Personally, I like to mount all NFS filesystems "nosuid" - and likewise for all local systems exported by NFS (I don't normally export / or /usr).  Most users have no business creating setuid programs in their filespace, and such a policy would most likely have prevented this breach even if the setuid binary was created by some other means.
