Explaining the external use of their LR key with "brute forced" has me worried, I don't see how that's computationally possible: https://bitcointalksearch.org/topic/m.1068030
What additional security practices are put in place in case the hackers are able to extract new replacement keys easily?
They are preparing a full write up for the community including screenshots, ect.
Did this ever happen?
did the write-up and screens happen?
Nope.
Im sure if there is enough demand, they will do it.
