   Ex-Mt. Gox CEO Found a Spy in a Ledger: Mark Karpelès

   Mark Karpelès, the former CEO of Mt. Gox, tells the story in his own words: how he bought the exchange in 2011 with no money down, the June 2011 hack, the 2013 US seizure and blocked wires, a year detained pending trial, and the bankruptcy that is still being closed today. Then the story that brought him back into the spotlight: a cheap Ledger Nano X that turned out to hide a spy implant, how it reads your 24 words and what the new mass-produced version looks like, and the antenna detector he is building to catch it. Mark's statements about Ledger and the implants are his own account and opinion. Ledger has confirmed at least one implanted device sold by the reseller CryptoBilis and says devices bought directly from Ledger show no sign of tampering. ES: Mark Karpelès, ex CEO de Mt.
