Vulnerable wallet range of Trust Wallet on iOS with CVE-2024-23660. Vulnerable wallet range of Trust Wallet on iOS with CVE-2024-23660.
See https://milksad.info/posts/research-update-5/ for details. See https://milksad.info/posts/research-update-5/ for details.
## Anomaly
One used wallet in the "B" range is also present in the "A" range, and therefore its addresses are in both victim lists.
This is an anomaly of the PRNG behavior, which generates a very simple entropy output (consisting of just all binary zeros) at a certain PRNG index. The output happens to be identical with [a well-known BIP39 example mnemonic](https://github.com/trezor/python-mnemonic/blob/b57a5ad77a981e743f4167ab2f7927a55c1e82a8/vectors.json#L4-L7), explaining its usage. In other words, this weak wallet is not unique to this specific weak range.
