# Mark Karpelès Catalogs 14 Ledger Devices in Tampering and Counterfeit Cases By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/32155 Published: 2026-10-15T01:11:27.000Z Updated: 2026-10-15T01:11:27.000Z Section: Technology > Former Mt.Gox CEO Mark Karpelès’ personal compilation covers seven named sellers and invites submissions of additional cases. Former Mt.Gox CEO Mark Karpelès has assembled a public catalog of 14 Ledger hardware wallets tied to tampering or counterfeiting cases, creating a single index of devices flagged for security concerns. Karpelès’ listings cover seven named sellers. Examples include devices with added circuitry and counterfeit units missing a security element, and each entry links to an underlying report. The page draws on public reports and images posted on X. The catalog is a personal open-source intelligence project, not an official Ledger investigation conclusion. It also accepts submissions of additional cases. Karpelès previously warned that altered Ledger devices could expose wallet recovery phrases, a concern covered in TokenPost’s [earlier report on his warning](). ## Links in this article - [earlier report on his warning](https://www.tokenpost.com/news/technology/29128)
