CVE-2025-6666Public exploit

Ignition-key cloning via globally reused secret

Published Nov 29, 2025 · Updated Aug 17, 2026

Hard-coded cryptographic keys in motogadget mo.lock RFID 20251125 allow physically proximate attackers to clone ignition keys. The NFC handler accepts a globally reused secret and validates a captured 7-byte key UID against an exhaustible 16-bit password space. Brief contactless access to a legitimate key and an NFC emulator are required; a clone authenticates like the original and can switch vehicle power.
