Title: Half of seed compromised?
Post by: nostrings on July 08, 2018, 11:50:47 PM
If someone found the first six words of my electrum seed is it still safe or do you guys think I should change to a new wallet?

If that person found the first six words, he probably knows all of it. Would recommend to change, better safe than sorry. Change it asap, or generate a new seed or wallet.
So yes, you should change to a new wallet as soon as possible.

Yes.

Even if it's unlikely, this increases his chances of brute forcing your wallet seed if he ever wants to try. Don't play with your money. Creating a new wallet isn't that hard.

i think you was 50% unsafe. you will be a victim of brute-forcing.
its better generate new seed and move all your assets to a new one

With the first 6 words known, there are at most 262 (about 4,000,000,000,000,000,000) seeds to guess. A PC that can check 1 billion seeds per second is guaranteed to find your seed in less than 120 years. While that may seem like a safe period of time, a sufficiently motivated attacker could acquire 1000x more processing power (for example) and crack your seed in less than a month.

why 62? am i missing something here?
there are 2048 (211)possible words and the seed is either 12 or 13 words depending on the version of Electrum generating it first. so it will be 2116=266 and 2117=277 respectively.
