This raises a new application for some of the recovery tools we use. One of
them restores the server system disk to the state it was saved in every
time
the server reboots. For a public situation like a library, you could reboot
the server each night and in the process restore it to the clean state it
was built in.

Things like this scare the crap out of me being the network manager for a
Library! You never know where patrons are browsing or what they are loading
on a public terminal or what is stuck in cache on your Citrix servers. JK

Subject: New trojan turns home PCs into porno Web site hosts
Hi,
Some individual appears to have hijacked more than a 1,000 home computers
starting in late June or early July and has been installing a new trojan
horse program on them. The trojan allows this person to run a number of
small Web sites on the hijacked home computers. These Web sites consists
of
only a few Web pages and apparently produce income by directing sign-ups to
for-pay porno Web sites through affiliate programs. Spam emails messages
get visitors to come to the small Web sites.
To make it more difficult for these Web sites to be shut down, a single
home
computer is used for only 10 minutes to host a site. After 10 minutes, the
IP address of the Web site is changed to a different home computer. The
hacker is able to do this quick switching because he has installed DNS name
servers for his domains on other home computers under his control. The DNS
name servers specify that a hostname-to-IP-address mapping should only live
for 10 minutes.
Over the long July 4th weekend, some of these same Web servers were used in
an apparent phishing scam to collect stolen PayPal passwords and credit
card
numbers. Silicon.com has an article about this scam:
Russian hackers behind fake PayPal email scam?
http://silicon.com/news/500013-500001/1/5061.html
Joe Stewart of LURHQ has obtained a copy of the trojan which he has named
Migmaf. His analysis of the trojan can be found on the LURHQ Web
site:
http://www.lurhq.com/migmaf.html
The initial theory was that the trojan was installing a mini-Web server on
hacked computer to host the porno Web sites. However, Joe's analysis shows
that the Trojan is actually a reverse HTTP proxy that makes a home computer
act as a front for a home base Web server.
The New York Times is also running an article about the trojan in its July
11th edition of the paper:
http://www.nytimes.com/2003/07/11/technology/11HACK.html?hp
Some of the domain names used by the Web sites of the trojan are:
onlycoredomains.com
pizdatohosting.com
bigvolumesites.com
wolrdofpisem.com
arizonasiteslist.com
nomorebullshitsite.com
linkxxxsites.com
I've been monitoring these domains since July 5th and found over 2,000
unique IP address used by hosts in these domains. Almost all of these IP
addresses are for commercial ISPs used by home computer users. AOL.COM was
the most used ISP.
One interesting feature of the trojan is that it times the connection speed
of a home computer that it is running on and reports the connection speed
back to home base. The home base computer seems to only select a computer
to run a reverse proxy server or the DNS name server if the computer has a
high-speed cable or DSL Internet connection.
It is not known at the present time how the trojan gets installed on
people's computers. My theory is that the Sobig.e virus might be involved,
but the evidence is not strong at the moment.
