This is what I found, posted in a short space of time. I think the op wrote his own thoughts, idk.
OP's post refers to the Exmo exchange hacking case that occurred last year, this is the stolen btc https://blockchair.com/bitcoin/address/1A4PXZE5j8v7UuapYckq6fSegmY5i8uUyq.

Actually the total loss is more than that according to this article. It makes sense that the hunt for hackers is taking longer (7 months) and hasn't been closed yet. No recent news found regarding the OP's post, maybe he got the info from "insiders".
