Isn’t It Ironic: Mt.Gox Hacker Demands Ransom From Exchange Users To Not Reveal Their Personal Data

The bankruptcy of the once largest Bitcoin exchange may be history, but now the real drama begins.

First, over the weekend, allegations surfaced that not the whole truth may have been revealed during the heartfelt announcement by Mt. Gox CEO, Mark Karpeles, who claimed that $400 million in Bitcoin were stolen by hackers. As Forbes reported, hackers took over the Reddit account and personal blog of Mark Karpeles, to reveal that the exchange he ran had actually kept at least some of the bitcoins that the company had said were stolen from users.

“It’s time that MTGOX got the bitcoin communities wrath instead of [the] Bitcoin Community getting Goxed,” wrote the unidentified hackers, referring to the multiple occasions over its three year history when Mt. Gox has gone offline, delayed trades or suspended withdrawals, events so common that Bitcoin users coined the phrase to be “goxed”–to suffer from Mt. Gox’s technical glitches.

In addition to merely allege, however, the hackers provided proof:

The hackers also posted a 716 megabyte file to Karpeles’ personal website that they said comprised stolen data from Mt. Gox’s servers. It appears to include an Excel spreadsheet of over a million trades, a file that purports to show the company’s balances in eighteen difference currencies, the backoffice application for some sort of administrative access to the databases of Mt. Gox’s parent company Tibanne Limited, a screenshot of the hackers’ access to those databases, a list of Mark Karpeles’ home addresses and Karpeles’ personal CV.

In the hackers’ summary of Mt. Gox’s balances in various currencies, they point to a claimed balance of 951,116 bitcoins, which they take as evidence that Mark Karpeles’ claim to have lost users’ digital currency to hackers is fraudulent. “That fat fuck has been lying!!” a note in the file reads.

It remains unclear at this early stage in the MtGox bankruptcy if indeed Karpeles ended up Madoffing some or all of the Bitcoin entrusted to him: Forbes notes that “the Bitcoin community has been puzzled by the apparent lack of movement of Mt. Gox’s bitcoins since the company declared bankruptcy last month. Despite stating that it lost 850,000 bitcoins in total in its bankruptcy filing, Bitcoin experts haven’t seen the movement of those coins in the Bitcoin blockchain, the public ledger of transactions that prevents fraud and forgery in the Bitcoin economy.”
