If I have a 24 word seed, and I split it into 2 - 12 and 12
If an attacker somehow finds either the first 12 words or the 2nd 12 words, is there anyway they can use that to easily derive/find the second 12 words? or am I as safe as If I simply had a 12 word seed (which many wallets use?)
The chances that hackers can brute force the whole seed phrase from just twelve seed phrase is possible with powerful computional algorithmic tools, very possible tools like btcrecover can be able to do it with high computational power. It is not good to split your seed phrase, instead you can use shamir sharing for such in a way the seed phrase can be perfectly divided and splitted into secrets which is best for this.
