Hi Dan

thanks for the update, you mentioned something of the kind last week.

I am terribly sorry to hear that, as being hacked is the equivalent of being
raped and murdered, at least that's what it feels like, from what I remember

I once researched an published an article for IT week, ZDNet must have been
over ten years go, about hacker culture. I dont remember the name of the guy
who spoke to me, but he had started a small security firm somewhere around
London, He explained all about red hats and black hats etc
It was an extremely informative experience.

He told me that when someone hacks our site, is often 'doing us a favour'
I thought the guy was being sarcastic but he was serious, I understood later

He explained that too often people disregard security matters etc etc and
(cause they are busy concentraing on the front end or other matters
perhaps?) and bringing down their sites was the only way to make them face
the fact that their servers and systems had simply not secure enough, and
obviously nobody was paying attention

Many of us have been busy elsewhere, but I think this experience should be a
learning one, if anything

I was wondering why the emphasis was on FOAF+SSL lately, and today I went to
do some reading, there is some recent literature that maybe we should catch
up with

I think if FOAF was *my* baby I would try to find out who hacked it or at
least how, and reverese engineer the security strategy from a vulnerability
assessment. Get hackers to do do vulnerability assessment, was the bottom
line of that article

I dont know enough how how the server were set up to give input, but let me
find them guys again

search for ' FOAF exploit'
