Have you checked whether this particular passphrase has been part of a prior leak? You can check here:
https://haveibeenpwned.com/PasswordsIt would be interesting to know whether our brainwallet sweepers are using publicly available password lists or have some pimped collections of their own.
This password has been seen 1,164 times beforeTurns out it's not such a mysterious password after all; checking further, it appears in the password lists I downloaded. I thought my system had found it through mangling of lyrics (which it may have still done, independently). The password for 1GkGD48ucUKCwPkwRyH1bDLJTAdeHVn2xR is "loveisallyouneed"
Alright, that's slightly less worrying then.
I was expecting something along the lines of "l0ve1s4lly0un33d" or a 1337 version of "Hey Jude" which would have implied a far vaster lookup table. (assuming it isn't already. well, probably now it will be.)
