If you use one anyway, buy only direct from ledger.com, treat any device that arrives already set up or with a printed seed as compromised, never restore an existing seed onto a device you didn't buy direct, and update only through the official Ledger Wallet app

Ledger says the secure element, OS and servers were not compromised.
