ChainCatcher 消息，据 The Block 报道，Ledger 旗下 Donjon 安全团队在实验室环境下，通过精密激光攻击绕过 Trezor Safe 7 所用 TROPIC01 芯片的固件验证机制，可在攻击者持有设备实物的前提下加载未授权固件。
芯片厂商 Tropic Square 进一步发现，该芯片用于 PIN 验证的 MAC-and-Destroy 安全机制存在额外攻击路径，但将在强化版芯片于 2026 年底推出前暂不公布细节。
Trezor 表示，PIN、助记词备份和私钥从未存放在单一芯片上，已通知合作方且普通用户无需操作，目前可通过关闭芯片 MAINTENANCE 模式降低攻击可行性。
