Employees of the same company targeted the email accounts of Laura Codruta Kovesi a few years ago (she’s now the first ever European Public Prosecutor [1]).
Back at that time she was the chief of the Romanian anti-corruption agency and she was doing a pretty good job, which was unfortunate for some of the local oligarchs and corrupt politicians who tried everything to bring her down. Afaik the Black Cube employees’ hacking actions were pretty lame, I remember reading that some of them had checked in at one of the most expensive Bucharest hotels during their operation, literally a couple of hundred meters away from one of the headquarters of our local counter-intelligence agency. I had been under the false impression that if you try to carry out such an action you at least try not to phisically show yourself in front of the people who are supposed to catch you.
