Trezor warns some of its wallets may hide a seed-stealing implant

A Trezor Safe 5 sold by CryptoBilis, the reseller linked to the recent Ledger wallet drains, may contain a hidden implant that steals the owner’s recovery phrase, Trezor has warned. Trezor is a Czech company and part of SatoshiLabs Group. It has made hardware wallets since 2014, and its current models are the Safe 3, Safe 5 and Safe 7.

Do this now

Check Trezor's advisory for a fix and avoid using any Safe 5 bought from CryptoBilis meanwhile.

## Steps
1. Search the repo, its CI and infra config for the affected product. If present, report the version in use and whether it's affected.
2. No source names a fix yet; check the vendor advisory. Until one ships: restrict network access to it.

## Report
A table: file, product or package, version in use, affected yes/no, exact fix. Then anything a human has to check outside the repo.
