==== 1. In Focus: Strengthen Browser Security with Third-Party Solutions 
====
   by Mark Joseph Edwards, News Editor, mark at ntsecurity / net

If you subscribe to our WinInfo email newsletter, then you've probably 
read stories by Paul Thurrott that discuss how Microsoft will handle 
improvements to Internet Explorer (IE) in the future. If you don't 
subscribe to the newsletter and want to, then visit the home page below, 
where you'll find a link to the subscription form.

As you know, it's been quite some time since Microsoft released a new 
version of the browser. Meanwhile, other browsers, such as Opera 
Software's Opera and Mozilla Firefox, have added considerable new 
features and functionality. But Microsoft has decided that it will 
introduce future IE improvements via service packs--it won't offer newer 
versions of the Web browser as standalone software because the company 
considers IE an integral part of the OS. 

The recent Windows XP Service Pack 2 (SP2) offers improvements to the 
underlying security of the OS and various components, including IE. 
Microsoft isn't planning to offer similar improvements to Windows 2000 
and earlier OSs. 

Many of you can't upgrade to XP yet for a variety of reasons, but in the 
meantime, you still want to improve overall system security. You can 
gain some of XP SP2's improvements by using third-party products. In at 
least one case--Windows Firewall--third-party products are typically 
superior. Because Windows Firewall allows all outbound connections 
without any means to control them, it's probably a wise idea to use a 
third-party firewall on systems on which you require precise control 
over network traffic. 

To improve the IE security on Windows 2000 and previous OSs, three 
options immediately come to mind, although there are probably others. 
One option lets you keep using IE as your primary browser; the other two 
options recommend that you use another browser as your primary browser 
and use IE only when you have to for whatever reason. I describe the 
options below in no particular order.

One option is to add PivX's Qwik-Fix Pro to your systems to help you 
modify IE zones to lock down the browser and prevent malware from 
exploiting the system. Another option is to purchase a browser such as 
Winferno Software's Secure IE 2004, which is an IE replacement that 
offers better security than IE versions prior to XP SP2's. The third 
option is to use a free third-party browser such as Mozilla Firefox or 
Opera Software's Opera, both of which offer functionality similar to 
that found in IE under XP SP2.

Qwik-Fix Pro and Secure IE 2004 cost money, which of course is 
reasonable to expect. Opera is available for free if you're willing to 
view banner advertising while you use it; if you buy it, you can use it 
ad-free. Firefox is open source and as such is available for free and 
without banner advertising.

JPEG GDI+ Trojan Unleashed
   It was only a matter of time before someone unleashed malware that 
exploits the JPEG GDI+ vulnerability. Over the last two weeks, 
various people have released proof-of-concept code. Now someone has 
unleashed a JPEG file that causes a buffer overrun and runs shell 
code on the affected system.

More JPEG GDI+ Exploits
   As could probably be expected, intruders have begun using AOL Instant 
Messenger (AIM) and other methods to exploit unsuspecting users who 
have the JPEG GDI+ vulnerability. At least two new Trojan Horse 
programs have been unleashed.

Welcome to the "You've Been Hacked" Blog
   We've added a second security blog, "You've Been Hacked," hosted by 
Brett Hill. Over the next few months, Hill will host a frank 
discussion of security issues related to Microsoft OSs, services, and 
products. As the blog title suggests, the blog will focus on what to 
do if you think you've been hacked. We want to hear from you about 
your experiences, questions, and concerns.

Check out this recent entry in the Security Matters blog:

Trojans with a Twist  
   Trojan horse programs are a bad enough problem because they can allow 
remote access to a user's computer. One would think that having a 
firewall in place would prevent a Trojan from opening back doors in 
case of infection. But Windows Firewall won't prevent the 
Win32.Surila.K Trojan from opening a back door on your system. 

==== 4. Instant Poll ====

Security Forum Featured Thread: Disabling .vbs Files in an OU
   A forum participant is looking for a way to use a policy to disable 
the use of some .vbs files in an Active Directory (AD) organizational 
unit (OU) while allowing the use of some .vbs files that he approves 
of. His understanding is that he can implement only an "all or 
nothing" policy and wonders whether anyone knows a way around this 
limitation. Join the discussion at

Spam Solution Adds User Quarantine Features
   Trend Micro announced new End User Quarantine (EUQ) features for 
Trend Micro Spam Prevention Solution (SPS) to reduce Help-desk 
burdens, to help corporate users manage their own "approved senders" 
lists, and to improve accuracy and effectiveness. EUQ, a free add-on, 
quarantines suspicious "graymail" messages (i.e., messages not 
clearly identifiable as spam) into Microsoft Exchange Server folders 
for each user. Thus, SPS users have instant access to potentially 
important messages and can individually approve any problematic 
senders. EUQ improves SPS's reporting and management capabilities and 
decreases the number of false positives while increasing the spam 
detection rate.
