Well, it seems unfair to say "investors lost 500k" if they weren't really investing in the ICO so much as taking the bait on a phishing email, which is what it sounds like happened. If a hacker took control of their domain and Slack, and socially engineered people into sending funds into the hackers' personal accounts (which is what it sounds like has happened), Enigma never really had the funds to lose in the first place themselves.
