According to ME News, on October 10 (UTC+8), Mark Karpelès, former CEO of Mt. Gox, disclosed in a post that a Ledger hardware wallet he received appeared to have been implanted with a spy module. The device originated from Malaysia; its outer shrink-wrap packaging was intact, and anomalies were difficult to detect immediately upon opening—the implant was concealed in the location where the screen’s original cushioning should have been. Karpelès further explained that the module includes an LTE communication component, an antenna, an eSIM, and a microcontroller connected to the Ledger’s SPI bus, enabling it to analyze characters displayed to the user and transmit relevant data after the recovery phrase is set. Attackers could then monitor the victim’s wallet address and choose an opportune moment to transfer assets. He urged users to follow Ledger’s official guidelines to inspect their devices.
