Casa(@CasaHODL):Bitcoin key generation depends on entropy: the randomness behind your seed. When that randomness is weaker than expected, the seed is guessable no matter which device holds it or how long the phrase is. July's Coldcard firmware disclosure made that concrete for a lot of bitcoiners. If you generated a seed on affected firmware and later moved it to a different wallet, the weakness moved with it. Do you know where the randomness behind your seed came from?
