The Safe team responded to the blind signature security incident and suggested using multiple signing devices from different vendors to enhance the visibility and security of transactions. They are also exploring technologies such as conditional signatures to provide more contextual information without compromising security.

<p>According to TechFlow news, on October 18, the Safe team reviewed the security incidents mentioned in the post-mortem report of Radiant Capital, noting that the Safe {Wallet} front-end functioned normally, but external devices were compromised during the signing process. This allowed hackers to replace transaction data and trick signers into signing malicious transactions. The Safe team believes this incident highlights the risks of blind signing, where users approve transactions without fully viewing the transaction details, especially when using hardware wallets. To address this issue, Safe recommends using multiple signing devices from different vendors (for example, a combination of Ledger and Trezor) and connecting these devices through trusted interfaces to enhance transaction visibility and security.</p>
<p>Additionally, Safe is also exploring technologies like conditional signing to provide more contextual information without sacrificing security. The Safe team is considering directly calculating the Ledger hash in its interface so that users can verify the hash displayed on the hardware wallet and the interface. The Safe team emphasizes that all parties in the ecosystem need to collaborate to address the issue of blind signing and is committed to working with hardware wallet providers and the community to improve transaction and message signing processes.</p>
