SlowMist’s Yu Xian: Ledger Flex Possibly Tied to CryptoBilis Tampering Case

The shift from Nano X to Flex matters because the concern is no longer a single model but the reseller channel itself: if tampering happened at CryptoBilis, the device model is incidental, and any Ledger unit passing through that supply chain is exposed. That reframes the risk from a product flaw to a distribution-integrity problem, affecting buyers who assume sealed retail packaging equals a clean device. The open question is whether SlowMist's tracking confirms tampering in the Flex unit and whether other resellers show the same pattern.
