The Mt. Gox drama continues this weekend with an alleged hack that uncovers customer balances and transaction data from the exchange, which recently filed for bankruptcy protection and claims to have lost hundreds of millions of dollars worth of bitcoin.
The data dump, which exceeds 700MB, includes a balance sheet that states a bitcoin balance of over 900,000 BTC, leading many in the bitcoin community to speculate that Mark Karpeles, the exchange’s CEO, has made off with the cash.
In addition, several executable files were included in the data leak, which are said to be (but not confirmed) proprietary software used by the exchange (see screenshot above).
“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 dump reads [link].
Some of Karpeles’ information was also compromised in the hack, including his resume and two home addresses. His blog was also hacked – but has since been taken offline.
Elsewhere, a user on the BitcoinTalk forum claimed to have 20+ gigabytes of customer data (including ID scans) for sale for about 100 BTC, says Forbes. The post was subsequently removed by the forum moderators.
If anything, the hack outlines that less-than-impressive security behind the world’s first bitcoin exchange. Also of interest in the data dump (as outlined by TechCrunch), a note: “I hated working with you. You deserve everything you get for what you did.”
