also, I came across this article today http://www.wired.com/2015/07/brainflayer-password-cracker-steals-bitcoins-brain/. would our hd wallets and the 24 word secret phrase we use to generate the private key for ledger and hw.1 be affected by this?

that's not a risk, brainwallets are easy to crack because the passphrase is the entropy of the seed, and we are not a very good source of entropy. The mnemonic phrase works the other way round : the words encode the entropy of the seed, which is chosen by a proper random generator.
