from the Analysis that the article claims identified "thousands of lines copied of code" (sounds like they copied a blacklist):
We found evidence that a number of these blacklists have been taken from the American-made filtering program CyberSitter. In particular, we found an encrypted configuration file, wfileu.dat, that references these blacklists with download URLs at CyberSitter's site. We also found a setup file, xstring.s2g, that appears to date these blacklists to 2006. Finally, csnews.dat is an encrypted 2004 news bulletin by CyberSitter. We conjecture that this file was accidentally included because it has the same file extension as the filters.
