Enigma.co which was conducting a presale was hacked. Hackers put up a new page at enigma.co domain with their own eth address and sent emails asking people to deposit in that address. Since the official website itself was compromised and contained the hacker's ethereum address, many users have deposited money into the fake address. Almost 1100 ether have been deposit there till now. The website is now offline. However hackers have control over their social accounts - both telegram and slack.
Hacker's eth address seems to have already collected a massive $400K
