Just out of curiosity, I wander what could be the possible 'gain' for attacker by attacking BCT forum, other then mental satisfaction ?
Yes, a lots of user contact data, related to CryptoCurrency which can be use for other phishing attack...
Other then above, what could be the 'direct' gain he/she/they (The attacker) had in mind at time of attacking??
Cheers!
