How to steal Bitcoins that are protected by weak passphrases

Warp Wallet has had a 20 BTC bounty on cracking an 8-bit alphanumeric password for a few months now, still unclaimed: https://keybase.io/warp

There are safe(r) ways to use a brain wallet, but it shouldn't be done without understanding the math and the risks. At the end of the day, redundant and physically secure paper wallets will always be the best option.

I guess scrypt makes it much harder in memory requirements to bruteforce dictionaries and famose phrases/documents although still risky with keyloggers.

The most promising web wallet i've seen so far is https://greenaddress.it which seems pretty much like "Electrum" online but with two factor which in theory means a local keylogger can't steal your bitcoin.
