RE: New attack or old Vulnerability Scanner?

Those are connect attempts FROM a vulnerable unpatched IIS boxen. If you run an Apache server, or you run a fully patched IIS server, then you have nothing to worry about. There is pretty much nothing you can do to stop the attacks except to potentially write to the ISP and have them notify the owner. I actually count the number of these on my web site with a Perl script that I'd be happy to post if you like.

Subject: New attack or old Vulnerability Scanner?

Hello,

Does anyone recognize this pattern of a TCP connect scan, then 65 GETs?

Note that it also included: "User-Agent:.Mozilla/3.0.

(compatible;.Indy.Library)...."

For which my googling tells me that this attack/scanner is probably

built using Borland Delphi/C++ Builder suite.

I've so far received 3 of these from 2 different IP addresses.

The first two were from a Comcast cable user.

The last was from a Cox Communications IP.

Thanks,

Mark Embrich
