Following the MtGox Bitcoin exchange losing millions to a hack and filing for bankruptcy, anonymous attackers took over the personal blog and reddit account of MtGox CEO Mark Karpeles on Sunday.

After seizing control, the hackers posted (Pastebin) a message to the two spaces detailing their findings and the reasoning behind the attack.
“It’s time that MTGOX got the bitcoin communities [sic] wrath instead of Bitcoin Community getting Goxed,” the message reads. “This release would have been sooner, but in spirit of responsible disclosure and making sure all of ducks were in a row, it took a few days longer than would have liked to verify the data… Included in this download you will find relevant database dumps, csv exports, specialized tools, and some highlighted summaries compiled from data. Keeping in line with f**king Gox alone, no user database dumps have been included.”
Forbes reports the 716 megabyte file placed on Karpeles’ site included items like his home address, CV, and an Excel spreadsheet that seems to document more than a million trades. But the most interesting piece of information shared is a summary of 18 different currency balances—with 951,116 bitcoins listed. In light of the 850,000 bitcoins supposedly lost in the recent attack, the hackers concluded this figure demonstrates fraud.

The footnote reads, “That fat f**k has been lying!!”
