Ledger’s latest research revealed a subtle flaw in Tangem’s firmware that could allow a laser attack to reset a card’s password. The vulnerability hinges on a missing check during the recovery state, letting an attacker overwrite the stored credentials if they can precisely target the device. While the mechanics sound technical, the point is that a physical attack could, in theory, compromise a wallet that otherwise appears secure.
Tangem has responded by stressing that the likelihood of such an attack in everyday use is virtually nil. The company points out that a laser attack would need specialized equipment, precise alignment, and a willingness to target a specific card—conditions that are far from common in typical retail scenarios. Nonetheless, the discovery serves as a reminder that firmware integrity is critical, especially as hardware wallets become the primary custodial solution for many investors.
For retail users, the takeaway is to keep firmware up to date and to remain vigilant for any new security notices from wallet manufacturers. Physical security—such as keeping cards in a safe place and avoiding exposure to potential laser sources—adds an extra layer of protection. While the risk is low, the incident illustrates that even the most trusted hardware can have hidden weaknesses that need to be addressed.
In the broader market, Bitcoin is trading around $64,450 with a 2.6 % rise, and Ethereum sits near $1,799, up 2.9 %. Despite the extreme fear sentiment, the price action suggests a degree of resilience. As security updates roll out and the community keeps an eye on firmware audits, investors can expect the market to continue navigating through volatility while maintaining a cautious approach to custodial solutions.
