==== 1. In Focus: IE Exploit; Firewall Tests ===   by Mark Joseph Edwards, News Editor, mark at ntsecurity / net

As you probably know, really dangerous JavaScript-based exploits of 
Microsoft Internet Explorer (IE) are on the loose. The exploits take 
advantage of problems in JavaScript processing that allow injection of 
arbitrary code. Microsoft is working on a patch for the problems that's 
currently scheduled for release April 11--the company's scheduled 
monthly patch release date. 

Several attacks that use the exploits are under way. For example, one 
attack comes disguised as a BBC News story snippet. When a person 
clicks the link to read the rest of the story, the exploit is 
triggered. Ken Pfeil sent me a link to another site hosting an exploit. 
The exploit includes some shell code, but I didn't completely reverse-
engineer the exploit, so I'm not entirely sure what all it does. If you 
want to take a look, visit on port 80 with a telnet client 
and enter the command "GET /" to dump out the exploit code.

Ken also pointed out that some software, such as Microsoft SharePoint 
Server, can be configured to load files based on content instead of 
file extension. This means that an exploit can be packaged inside 
something as seemingly harmless as a .txt file to get past your 
defenses and will then be run by the software. This software capability 
undoubtedly adds to the danger level of the new exploits and other 

While you're waiting for Microsoft's patch, you might consider using a 
third-party patch from Determina or eEye Digital Security. I haven't 
tested either of these patches so I can't vouch for them, but both 
companies are reputable. Alternatively, you can disable Active 
Scripting in IE to stop the execution of JavaScript.

I tested one of the JavaScript-based exploits with Mozilla Firefox and 
found that it caused the system's disk subsystem to go into overdrive. 
There was so much disk activity that it took me more than 5 minutes to 
get Task Manager to open so that I could terminate the Firefox process, 
which stabilized the system.

I recently came across an interesting set of desktop firewall test 
results--at the Firewall Leak Tester Web site. The 2006 results show 
which desktop firewalls perform best in terms of outbound application 
filtering and the prevention of information leakage. Coming in dead 
last out of 16 desktop firewalls is Windows Firewall, which ships as 
part of Windows XP Service Pack 2 (SP2). This isn't too surprising 
given that Windows Firewall doesn't do outbound blocking.

So which firewalls are the best? When it comes to outbound application 
filtering, no other firewall beats Jetico Personal Firewall. Kaspersky 
Lab's firewall is the strongest in terms of preventing information 
leakage, with Jetico coming in a close second place. Overall, Jetico 
appears to make the strongest desktop firewall available, beating out 
other well-known firewalls such as those from Sunbelt Software (Kerio), 
ZoneLabs (ZoneAlarm Pro and ZoneAlarm Free), and Symantec (Norton). As 
a bonus, Jetico Personal Firewall is free. 

Check out the results at the URL below.

Beef Up Security for Your Mobile-Device Fleet

of Exchange Server 2003 Service Pack 2 (SP2) and the Messaging and

RoboForm 6.6's other new features include support for several new
