Counterfeit Ledger Nano S Wallets Found Siphoning BTC and ETH

Traders should note the following indicators of potential compromise:

• Out-of-box condition: Any device that arrives with a pre-configured recovery phrase or a pre-sealed package that appears disturbed should be treated as compromised.
• Purchase origin: Legitimate hardware should only be sourced directly from the manufacturer or authorized resellers.
• Physical anomalies: Unauthorized modifications often require physical alterations to the casing or the internal PCB, which may be detectable upon close inspection.

Implications for Hardware Security

This discovery serves as a reminder that the physical layer remains a primary target for sophisticated threat actors. While software vulnerabilities often dominate headlines, the physical modification of hardware is a more permanent and difficult-to-detect vector.

"The sophistication of these counterfeit devices suggests a targeted operation designed to mimic legitimate hardware while silently exfiltrating private keys from unsuspecting users."

Market participants relying on cold storage should prioritize purchasing hardware directly from official channels. If a device exhibits unexpected behavior during setup, such as lag or unusual prompts, it should be immediately discarded. The emergence of these modified units may lead to increased scrutiny of hardware supply chains and potentially tighter verification protocols from major manufacturers. Investors should also review the security measures discussed in recent reports on Grinex Exchange suspending operations to compare systemic versus physical security risks.

Traders must verify the physical authenticity of their cold storage devices before transferring assets, as hardware-level compromises are irreversible once private keys are exposed.
