Hmm...
I can't help wondering if there have been more of these "hacking" incidents where the intruder has quietly taken the data and not left any traces. Surely serious players (such as a nation state), would want to retain their access to the data for further mining when necessary.
Maybe somebody simply got careless, or some amateur blundered in and gave the game away. On the other hand, somebody may be making a very embarrassing, and public, point.
