No matter how it turns out... this will be bad for the game.
1) it was a legitimate spy sabotage within proper metagaming mechanics and CCP will not step in; or
2) it was a bug/hack and CCP steps in to reverse it.
If its (1) then it highlights CCPs shitty design (vote to declare war versus a single director in the executor corp presses a button to kill the alliance?) and the corporation and game loses a lot of credibility with a major faction of influential longtime players.
If its (2) then there will be howls of rage from BoB-haters for months that CCP favours that alliance and the company and game are corrupt.
Regardless, a perfectly balanced situation (i.e. BoB versus Goons in POS wars) has been severely upset and CCP can't come out looking good either way.
