I googled the name but couldn't find anything regarding the hack. Also, I took a look at the price chart fir the last 7 days and I don't see any significant drop during this period!

However, I found this in their twitter:
The recent situation with inaccurate balances was a result of a mistake in IDO allocation. The team has bought out the tokens that entered the market by mistake.
Is this what you meant by a hack? and can you please provide more information about what happened exactly and when and provide some evidences like chat logs?
