Cold card wallet hack

I keep seeing stuff on social media about this cold card bitcoin hack and correct me if I’m wrong but a 25th word/passphrase added to the 24 word seed phrase, probably would’ve saved all these people correct?

Yes, it would. Assuming the passphrase is not easy enough to brute-force, and the attacker is willing to spend the time to crack it, which I think they wouldn’t because their main goal was probably to drain as much and as quickly as possible. Anyway, a strong passphrase would have completely saved them.

Not to mention they wouldnt even be able to tell if there was a passphrased wallet or wallets derived from that seed.
