CVE-2023-48034Public exploit

Keystroke decryption and injection via one-byte key

Published Nov 27, 2023 · Updated Aug 2, 2024

Weak encryption in the Acer Wireless Keyboard SK-9662 allows physically proximate attackers to decrypt and inject wireless keystrokes. The radio protocol derives an AES-CBC keystream from a zero-padded one-byte key and exposes its random byte in each 12-byte payload, leaving only 256 keys to test. Capturing one 2.4 GHz packet is sufficient to recover the key within seconds, enabling real-time keylogging and arbitrary input to the paired computer.
