Hackers claim MtGox still has access to ‘missing’ Bitcoin

medium_10307527573When MtGox suddenly shut up show with $400 million worth of ‘missing’ Bitcoins last month, the owners of the exchange stated that hackers were responsible for this loss. Whoever had raided MtGox has successfully exploited the transaction malleability bug to divert these funds from the exchange, or so its owners claimed. But suspicions have lingered over how true the hacker story really is, with some claiming that the owners may have simply pocketed the cash for themselves.

Now, following MtGox’s unnerving silence since it made an application for bankruptcy just over a week ago, a group of hackers claims to have broken into the site’s network to find out what the real story is.

According to a report in Forbes, the hacker or hackers successfully compromised Mark Karpeles’ personal blog and Reddit account, before using these two platforms to post ‘evidence’ that the MtGox CEO still had access to some of the missing Bitcoins. They also provided a series of files to support these claims, including a spreadsheet that details over a million Bitcoin transactions; a screenshot that appears to confirm the hackers gained access to MtGox’s network; and Karpeles’ home address.

The hackers also presented a file that show’s MtGox’s bank balance in 18 different currencies. Most tellingly, this file shows that it still has a balance of 951,116 Bitcoins – something that hackers say is ‘evidence’ that the exchange’s owners still have quite a stash of BTC. As the hacker’s so eloquently point out, “That fat fuck has been lying!!”

Here’s the full text of the message from the hackers:



First and foremost, this is not Mark Karpeles. Fuck that bitch-titted motherfucker.
It’s time that MTGOX got the bitcoin communities wrath instead of Bitcoin Community getting Goxed. 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.

The files haven’t been confirmed as genuine, and even if they are real there’s no way of telling if they’re up to date. It could simply show money that MtGox once held, before the hackers made off with their booty – but then again, it could be further evidence of massive theft on the part of Karpeles and others at MtGox.

In its bankruptcy filing, MtGox claimed to have lost around 750,000 Bitcoins that belong to its customers, in addition to 100,000 of its own. However, Bitcoin users have yet to see these missing Bitcoins appear on the public blockchain, which suggests that whoever does have the money is keeping it stashed somewhere.

This weekend’s ‘hack’ comes just days after someone attempted to sell a file containing the personal details and passport scans of MtGox’s users on the BitcoinTalk forum. The ‘owner’ of that 20GB file offered it for sale for 100 bitcoins, “to make up for personal losses from MtGox closure”.
