Data compression method is still unknown. If you calculate entropy of the data, you will notice that it is definitely not encrypted. Probably it uses a modified version of propieritary Nintendo compression method described here: http://everything2.com/index.pl?node_id=1469892

The News Channel downloads data packages from Nintendo servers via plain HTTP connection. The official servers for the News Channel were discontinued on June 28, 2013; however, RiiConnect24 has since restored its functionality.

The data files are RSA-2048-SHA1 signed, and the LZ10 compressed content begins at 0x140. A Kaitai file documenting the file structure can be found here, and code used by RiiConnect24 to download news data and generate files is available here.
