Something w/MS Technologies. Ie. ISA Server (2004+) I believe, have whats called VPN Quarantine. Which allows you to check and limit access based on ie. If the user has proper virus definitions etc. before they get full access to your network. Just something I thought Id add. --- Jason -----Original Message----- From: Irwan Ismail [mailto:irwan.ismail () gmail com] Sent: Thursday, August 25, 2005 12:40 AM To: Matt Stockdale Cc: jeff () jeffbryner com; incidents () securityfocus com Subject: Re: cuebot-d infection method I think you should know that blocking ports at the firewall isn't enough anymore these days. With VPNs and remote access, your teleworker & mobile users can easily get infected at home (or wherever they may be) while there's an open path directly into your organization.

Jeff - I've just cleaned up four machines here, all Windows 2000. We're scratching our heads, as the "published" propagation method is over port 445, which wasn't open on the firewall. We suspect it may have come through the client's VPN access, or maybe someone wrapped this backdoor in another exploit for delivery.

Has anyone seen enough of this to know the universe of ways the pc gets initially infected? The pcs that have gotten infected have mcafee running on them which incorrectly picks it up as W32/Sdbot.worm.gen.by when a scan is requested. It didn't seem to pick it up *until* a scan was requested. The writeup at http://www.sophos.com/virusinfo/analyses/w32cuebotd.html fits the scenario, but it doesn't say exactly what the initial infection vector is. Thanks for any help. Jeff CISSP, GCIH, GCFA
