Somebody collected the still available firmware files for Samsung's WiFi enabled cameras (compact and mirrorless NX system): https://nxfiles.nx.tc/

I mirrored them (some 40GB including OSS dumps) and pulled some strings on the firmware files at https://op-co.de/blog/posts/samsung_nx_archaeology/ and https://op-co.de/blog/posts/samsung_wifi_cameras/

A specific open mystery is how https://nxfiles.nx.tc/files/Compact/SH100/Firmware/ interacts with the /social/columbus/login/direct API endpoint in order to login to F*book.
