CVE-2023-25758Public exploit

Seed disclosure via exposed secure-element communications

Published Feb 14, 2023 · Updated Mar 20, 2025

Seed disclosure in OneKey Touch through 4.0.0 and Mini through 2.10.0 allows physically proximate attackers to obtain the seed phrase. The firmware transfers secure-element protection material and the encrypted seed over board-level links that an interposed FPGA can capture and use to recover the seed. Exploitation requires device disassembly, physical access, and specialized FPGA equipment; successful extraction reveals the recovery mnemonic controlling wallet funds.
