When Mt. Gox lost almost $400 million of its customers’ digital currency in February, it seemed to be a complete failure of the company’s digital security. But in an interview with the Wall Street Journal, the now-defunct exchange’s chief executive said that old-fashioned physical security was a problem, too.
“We had some cases where a stranger sneaked in and took things away. We also have at least one former employee stealing the company’s data,” Mark Karpelès told the newspaper in his first public comments since Mt. Gox declared bankruptcy following the attacks. “I can’t disclose much due to the police investigation, but there were also physical attacks.”
