Direct-message manipulation via nonce and key-pair reuse
Published Jun 17, 2024 · Updated Aug 2, 2024
Cryptographic nonce reuse in FreeFrom - the nostr client before 1.3.5 allows man-in-the-middle attackers to manipulate direct messages. The app reuses a nonce and key pair across direct-message encryption operations rather than supplying a unique nonce for each operation. A man-in-the-middle position on the message path is required, and the reported consequence is direct-message manipulation.
