Caught something attempting to speed through my site with downloading on the agenda:
220.127.116.11 [bscop.bluesquirrel.com.] requested 340 pages as "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1.)"Went to Blue Squirrel's site to see what they were and big surprise they have some website downloading tools like Grab-a-site and WebWhacker.
Here's my favorite part where the Grab-a-site software's options default to stealth mode:
User Agent - Lets you set how Grab-a-Site reports itself to the web servers. By default, it sends "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1.)" which makes it look like an Internet Explorer version 6.0.This product may be responsible for some of the stealth activity we see in our log files and it's obviously trying to hide from webmasters otherwise the default UA would be the name of the product and not MSIE 6.0.
