Say I have two MetaMask accounts generated from the same seed phrase. If I accidentally expose one account's private key, could an attacker reconstruct the wallet's seed phrase and therefore the other account's private key?
I've seen this question asked in terms of a user recovering one account's funds when all they have is the second account's private key. While the answer should theoretically be the same, I want to be clear that I'm talking about an arbitrarily sophisticated and motivated attacker.
