If you're using a brainwallet, move your coins - NOW!

On August 7th I will be giving a talk at DEF CON about cracking brainwallets. As part of that talk, I will be releasing a fast[1] brainwallet cracker. I'm writing this post to provide a little insight as to why I'm giving away a tool that could be used to steal. I also hope that people who are currently using brainwallets will take notice and move to a more secure storage method.

SHA256 your passphrase IMMEDIATELY and move your coins to trezor, electrum, etc.

But electrum has a mnemonic passphrase that serves as a seed. And brainwallets are mostly a similar list of words.

So what i wonder, is this fast brainwallet hacker able to put together enough random words fast enough to hack electrum mnemonic passphrases too?
