[2016-02-10]Bitcoiners are just like everybody else: They use rubbish passwords

[trinaldao]

Don't pretend you can invent a strong enough, memorable password to protect your Bitcoins: crypto-boffins can crack the so-called "brain wallet."

In research published at the International Association for Cryptologic Research (IACR), University College London's Nicolas Courtois and Guangyan Song and White Ops' Ryan Castellucci benchmarked the Bitcoin secp256k1 elliptic curve, with depressing results.

The group managed to retrieve more than 18,000 Bitcoin passwords, they claim, using an Amazon EC2 m4.4xlarge instance. That yielded a rather stunning 17.9 billion passwords tested per US$1 spent, or less than $60 to check a trillion passwords.

If you're not using complex pass phrases, you're an idiot.

Complex Pass Phrase Examples:

• "I got my first blowjob @ 8:43pm on August 24th, 1975 in Dad's truck he let me borrow."
• "I bought my first beer @ Tim's Tavern for $1.25 on January 17th, 1978 @ 10:23pm!"

Do not confuse the newbies, they might just think this is a flaw in Bitcoin. The "brain wallet" is just a service built for users to manage their bitcoins with a friendly graphic interface. The private key for your Bitcoin address will never be compromised with this type of attack.

You will be a idiot, if you store all your coins in a brain wallet. Keep it in cold storage. My password adhere to Bitware's requirements : "I got my first blowjob @ 10:57am on September 28th, 1965 on the backseat of Mom's Tesla." ^hmmm^
