- Ledger Spy Implant Found in Additional Hardware Wallets, Karpelès Claims — this brief
Mark Karpelès, the CEO of Karpelès Lab and former CEO of Mt. Gox, has reported finding the controversial Ledger spy implant in additional hardware wallet devices. According to Unchained, the devices in question include a Ledger Flex and a Nano X, suggesting the issue may be more widespread than previously thought.
The latest version of the implant appears to be designed for mass production, according to Karpelès, which raises concerns about the potential scale of the tampering. This discovery comes after Ledger faced a significant security crisis earlier this year, with reports of vulnerabilities in their devices.
Cointelegraph adds that Ledger was contacted about the risks of tampered hardware wallets months before this latest security issue came to light. This prior knowledge further complicates the situation and questions Ledger's initial response to the security concerns.
Ledger, however, disputes these claims. According to their statement, an inspection of their German store stock showed no evidence of tampering. This discrepancy highlights the uncertainty surrounding the extent and nature of the issue.
The broader market context shows a slight downturn, with the total crypto market cap at $2.79 trillion and
