Yep, coming out of columbia.edu.
Called them and sent logs earlier today
(symantec: take note.. we saw it first)

funny ting, on the security section of their web site them mention that
they had their web site defaced and users redurected towards a porn site
I called them up, thinking that they might have staff on duty.. noop,
nothing, all phone lines, help desk, security phones have ' thank you for
calling when we are all home', press 0 for operator, nothing.

What source ip addresses are you seeing?
