Depending on your make/model/firmware re-vision you may be able to find a manifest file that includes a lot of the files installed and their md5sum.
But you can probably do better than that by just listing the usual places (this is *nix, it has dedicated places in the file tree for installed files).
executabiles: /bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin
libraries: /lib/* : /usr/lib/* : /usr/local/lib/*
Then all you have to do is look-up any of the names you don't recognize.
