Tampering Uncovered: Hardware Wallet Safety in Question Amid Global Incidents

Hardware Wallet Security Concerns

In 2026, six hardware wallet brands have disclosed security problems, with users losing crypto in only two cases, highlighting concerns over the safety of these devices. Despite this, Ledger and Coldcard users still experienced losses, emphasizing the need for improved security measures.

Weak Keys and Tampering Incidents

Weak keys, lasers, and data leaks have hit wallet makers in 2026, with Coldcard losses passing $115 million. Ledger's in-house security team used lasers to break chips in the Trezor Safe 7 in June and Tangem cards in July. Both attacks need the device in hand and specialist lab equipment.

Incident Response and Prevention

Trezor said user funds stayed safe. Tangem said the risk to everyday users was 'virtually non-existent' and noted the researchers work for a rival. BitBox fixed several firmware flaws its own engineers called severe. It reported no stolen funds. Other incidents exposed customers, not keys.

Global Impact and Recommendations

Six hardware wallet brands have disclosed security problems in 2026 '2026 might go down as one of the wildest years for hardware wallet security,' Wise Advice noted. Ledger confirmed Saturday that a victim's device carried an unauthorized hardware implant. In a Sunday update, it said every confirmed case involves Malaysian reseller CryptoBilis. On-chain investigators estimate losses near $90 million.

Conclusion

Despite the incidents, no security chip was cracked outside a lab this year, but Coldcard and Ledger users still lost money to weak keys and tampered devices. This highlights the need for improved security measures and shared anti-tamper and chain-of-custody standards among wallet makers.
