this attack was allowed by a coding error that mistakenly generated much weaker than intended entropy for seed generation.
bottom line: any wallet developer is capable of making a similar mistake.
This can be mitigated by not relying on any wallet to generate your seed words for you. Instead, you can generate your own near-perfect entropy offline simply by letting 11 coin flips choose each of your seed words from the list of 2048 BIP-39 words. Then tell your mobile wallet what your seed words are rather than the other way around.
