Former Mt. Gox CEO accused Ledger of false advertising, saying its security chip claims contradict its own documentation
PANews October 19 reported that former Mt. Gox CEO Mark Karpelès posted on X that Ledger's official support account had previously said its Secure Element chip could detect physical tampering and reject Genuine Check verification when “additional hardware” attempted to intercept signals. However, Ledger's own technical documentation explicitly states that if the original Secure Element remains intact,Genuine Check it cannot detect unauthorized physical hardware modifications such as spy implants, a direct contradiction. Karpelès noted that in less than 2 months, more than 90000000 USD reports had emerged of theft caused by such “additional hardware” intercepting signals, while Ledger had as early as 2026 published, in a March Ledger Academy article, content on mass-produced spy implants in multiple devices...
PANews said that former Mt. Gox CEO Mark Karpelès posted on X discussing Ledger's security statements.
02
According to Karpelès, Ledger's official support account had said that its Secure Element could detect physical tampering and would reject Genuine Check verification when “additional hardware” attempted to intercept signals.
03
Karpelès said that Ledger's technical documentation states: if the original Secure Element remains intact,Genuine Check it cannot detect unauthorized physical hardware modifications such as spy implants.
04
Karpelès noted that in less than 2 months, more than 90000000 USD reports emerged of theft caused by this type of “additional hardware” intercepting signals.
05
The original text states that Ledger, in a 2026 Ledger Academy article published in March, included content related to mass-produced spy implants in multiple devices.
AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
The core of the dispute is whether the detection capability described by Ledger's support account exceeds the actual detection scope stated in its technical documentation. Karpelès believes the two statements directly conflict, but the current material only recounts his allegation.
Why it matters to readers
If the relevant claims are indeed inconsistent, users may misjudge Genuine Check its ability to identify physical modifications or added hardware on devices, thereby underestimating security risks.
A hardware wallet does not mean it can automatically identify all hardware modifications. Beginners should distinguish between “device authenticity verification” and “detecting all physical tampering” as potentially different capabilities, and await further clarification.
Risks and unknowns
The material does not provide Karpelès's complete original X post, so all of his statements cannot be verified.
The material does not show the original text from Ledger's support account or the full context of the technical documentation.
The purported more than 90000000 USD reports of theft do not include source or verification information in the material.
The material does not include Ledger's response to the allegation.
There is no independent security research or audit in the material confirming the actual detection boundaries of Genuine Check.
The relevant sentence from the Ledger Academy article is truncated with an ellipsis in the evidence, so its complete content cannot be confirmed.
