Reports of cryptocurrency losses linked to modified Ledger devices sold through an authorized reseller, CryptoBilis, have exposed vulnerabilities in the hardware wallet supply chain. Ledger confirmed that an affected device contained an unauthorized cellular implant designed to steal user recovery phrases and send them over cellular networks. In response to growing security concerns, competing wallet maker Trezor announced it would reduce its number of resellers as a preventive measure.

Hardware wallets are widely considered a secure method for storing cryptocurrency offline to protect private keys from online hacking attacks. However, experts warn that the distribution process introduces a new chain of trust involving manufacturers, distributors, and intermediaries. Because modified devices can capture screen data without altering internal firmware, standard security checks and tamper-evident packaging cannot guarantee that a physical device remains untouched before reaching a buyer.

Security researchers suggest that hardware wallet manufacturers may need to overhaul physical designs to combat supply chain attacks. Potential improvements include transparent casings and tamper-resistant enclosures that force attackers to rebuild entire device housings to hide unauthorized modifications. Security advisors also recommend that users mitigate risk by spreading assets across multiple security providers rather than relying on a single device or vendor.

## Key points

- Ledger confirmed an unauthorized cellular implant was found in a wallet sold by reseller CryptoBilis, which captured recovery phrases.
- Competitor Trezor announced plans to cut its number of third-party resellers as a preventive security measure.
- Security experts caution that built-in security checks and holographic packaging seals cannot fully rule out physical hardware tampering.
- Proposed design solutions include transparent device casings and tamper-resistant housing to make unauthorized modifications harder to conceal.

## Questions and answers

### How were Ledger hardware wallets tampered with?

Unauthorized cellular implants were placed inside devices sold by a reseller. The implants captured user recovery phrases and transmitted them over cellular networks without modifying the device firmware.

### Can standard checks detect tampered crypto hardware wallets?

Not always. While manufacturers check device authenticity and holographic packaging seals, physical implants that capture screen data without altering firmware can bypass standard firmware security checks.

### How can crypto users protect against hardware wallet supply chain risks?

Security experts advise buying directly from trusted sources and spreading risk across multiple providers instead of relying on a single device or manufacturer.
