it is not an old version of C.A.T trading bot (Sampey's trade bot) it is not even a bot. it is a malware.
the website is just using a low res cropped screenshot of Sampey's trade bot and shows it as their "bot"
you can easily find the picture with a quick google search: https://bitcointalksearch.org/topic/m.18913289
i did download it (inside a snadbox for protection) and the file size is small (~6-7 MB) and it didn't open anything, any interface or something like that. it just started using my CPU to the max! and no interface appeared, that is mostly why i said it is just a malware not a copy of the bot with malware.
but it may also be because the sandbox was a windows XP so you may be right after all.
