Ledger Security Claim Questioned Over Discrepancy Between Support Statement and Technical Documentation

ME News reports that on October 19 (UTC+8), former Mt. Gox CEO Mark Karpelès posted a critique challenging Ledger Support’s previous statement. Ledger Support 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 support claim. Karpelès noted that reports within less than two months have already revealed over $90 million stolen due to such “additional hardware” intercepting signals, and that Ledger had published photos of spy implants on multiple device models as early as a March 2026 academic article. Given this known threat, does assuring users that authenticity verification can detect such modifications constitute misleading advertising? (Source: ChainCatcher)
