Ledger Security Claims Questioned Over Discrepancy Between Support and Documentation

ChainCatcher report: Former Mt. Gox CEO Mark Karpelès has posted a rebuttal to previous statements made by Ledger Support. Ledger’s customer service had claimed that the secure element can detect physical tampering and that unauthorized hardware attempting to intercept signals would fail authenticity verification. Karpelès pointed out that Ledger’s own documentation states that if the original secure element remains intact, authenticity verification cannot detect unauthorized physical modifications such as spy implants—directly contradicting the customer service claim. Karpelès noted that reports have already emerged showing over $90 million stolen due to such “additional hardware” intercepting signals, and that Ledger itself published photos of spy implants on multiple device models in a March 2026 academic article. Given this known threat, does assuring users that authenticity verification can detect such modifications constitute misleading advertising?
