I doesn't really matter if it is one word or a number.
It does matter whether its a word or a number. This determines the searching space and therefore the amount of
time you have to invest to crack that wallet.
Also you have have now exposed publicly that you phrase is compose out of 24 words
Most modern wallets use either a 12 or 24 word seed. Thats not an information which is hidden anyway.
so if the hacker finds your ip he could know you made a post on this forum about your wallet and finds out what exactly to look for.
For huge amounts thats true. But the average joe with a few btc shouldn't care too much about such targeted attacks.
It would be way more lucrative to just steal cryptos with malware.
