I am still looking for the break-in that predates this breakin, my memory is fucking horrible. I apologize. It will take me a while for me to find it.
This wasn't in 2002, this was back in the 90s, I want to say 1996 or 1997. The source code was back-doored. The advisory you found was for completely different break-in in 2002.
