Wasn't it Klaus who made some ridiculous statement like "no hackers work at ISS" at one point in time?
With a team like ISS X-Force, it would be silly to claim there wasn't any hackers involved.
Infact, I'm pretty sure there was quite a few Phrack articles written by ISS employees in their earlier life, under their irc names,,, myself included. ;)
I think most of the content that would have gone into Phrack in early days became posted as commercial vulnerability research later on.
Perfectly nice person period!
There's an old rivalry with ISS, and a thread about X.25 networks and 40hex puts me back in my Calgary head space.
