The development raises concerns about Ledger's transparency and accountability in handling security vulnerabilities, potentially affecting user trust and the broader hardware wallet market.

- Former Mt. Gox CEO Mark Karpelès claims multiple users alerted Ledger.
- Security researcher Joe Grand found a compromised wallet in March 2026.
Multiple outlets, including The Coin Republic and The Cryptonomist, report that Ledger was aware of suspicious hardware devices months before the October 2026 incidents. The Cryptonomist specifies that reports date back to at least December 2025, while The Coin Republic emphasizes that former Mt. Gox CEO Mark Karpelès knew of at least two people who contacted Ledger about altered devices but saw no public warnings. The outlets agree on the timeline and Karpelès' involvement but differ slightly in the emphasis on user reports versus internal findings.

- Ledger Faces Scrutiny Over Prior Tampering Reports Before $86M Crypto Hack — this brief
Ledger Wallet is facing scrutiny over its handling of earlier security reports following the $86 million cryptocurrency theft linked to modified hardware devices. The controversy stems from allegations that the company was aware of compromised devices months before the incidents occurred.
Former Mt. Gox CEO Mark Karpelès has been a key figure in raising these concerns. According to The Cryptonomist, Karpelès stated on October 16, 2026, that Ledger had been aware of tampering reports since at least December 2025. He questioned the company's response, noting that he knew of at least two individuals who had contacted Ledger about altered devices but had not seen any subsequent public warnings.
The Coin Republic corroborates Karpelès' claims, adding that security researcher Joe Grand also reported finding a compromised wallet in March 2026. This suggests a pattern of security issues that Ledger may have been aware of but did not publicly address.
The broader context involves the growing importance of hardware wallets in the cryptocurrency ecosystem and the critical need for robust security measures. As the total crypto market cap stands at $2.8 trillion, incidents like these can significantly impact user trust and market stability.
The current market data shows a relatively flat overall market, with 
Bitcoin down 0.60% in the last 24 hours. The Fear & Greed Index is at 55, indicating a state of 'Greed,' which suggests that while the market is not in panic mode, the Ledger situation could influence sentiment if more details emerge.
