Boileau, a consultant with Immunity Inc., said he did not release the tool

To use the tool, hackers must connect a Linux-based computer to a
Firewire port on the target machine. The machine is then tricked into
allowing the attacking computer to have read and write access to its
With full access to the memory, the tool can then modify Windows'
password protection code, which is stored there, and render it
Whole problem started when hackers created strip-down version of
Linux for Ipod and used it in few instances to hack companies
computers thru Firewire's DMA.
In addition to Firewire being expansion bus it is also peer-to-peer bus
allowing networking between computers while USB as peripheral bus
works only in Host-Client mode.
