Data disclosure via predictable Twofish message keys
Published Sep 18, 2024 · Updated Nov 21, 2024
Weak encryption in Victure PC420 1.1.39 allows man-in-the-middle attackers to read sensitive RPC data from captured network traffic. The anyka_ipc protocol builds each Twofish key by concatenating plaintext RPC method and ID fields with a fixed string, while the predictable ID is derived from time-seeded rand(). Man-in-the-middle attackers on the same Wi-Fi network or another traffic path derive message keys and decrypt protected credentials and control data; camera audio and video are transmitted without encryption.
