A Robust Combination from Symantec
   Staying on top of today's vulnerabilities and threats is one of the 
most difficult, time-consuming, and even risky tasks facing IT 
professionals like you. Never has it been so important to proactively 
manage your IT environment. Fortunately, Symantec can help.
   Symantec LiveState Patch Manager 6.0 helps keep your enterprise 
devices secure and available by identifying known vulnerabilities and 
then installing necessary patches on hundreds of systems in minutes, 
not hours. That includes mobile and remote devices, too. 
   For extra protection from threats that even the latest patches can't 
address, there's Symantec Client Security 3.0. With its exclusive 
intrusion prevention technology, Symantec Client Security 3.0 
proactively protects systems against known and unknown exploits before 
they can compromise your system, including spyware, adware, viruses, 
and other malicious intrusions. Learn more at

==== 1. In Focus: Honeypots That Collect Malware ===   by Mark Joseph Edwards, News Editor, mark at ntsecurity / net

The last two weeks, I've written about proactive honeypots that seek 
out malicious Web sites, two of which are unavailable to the public and 
one that you can download to run on your own networks. If you missed 
either of those articles, they're available on our Web site at the URLs 
below. This week, I'll discuss two "passive" honeypots--that is, 
honeypots that sit waiting for intrusion attempts. 
http://list.windowsitpro.com/t?ctl=1264A:4FB69 
http://list.windowsitpro.com/t?ctl=12649:4FB69 

Because honeypots present an attack point for potential intruders, 
they're useful in determining what sort of intrusion attempts are being 
launched against your network. In some cases, they can detect intrusion 
methods that are completely unknown to even the most up-to-date 
Intrusion Detection Systems (IDSs). 

I recently learned about two new honeypots. The first is mwcollect (at 
the URL below), which was released in April 2005 and is partially 
funded by The Honeynet Project. Mwcollect is designed specifically to 
collect malware--thus the "mw" prefix in the mwcollect name. The tool 
runs on Linux and OpenBSD and can also run on Cygwin, a Linux 
environment that runs on Windows platforms.
http://list.windowsitpro.com/t?ctl=12653:4FB69 

Mwcollect is a little different from typical honeypots because it was 
originally designed to collect bot software, but the current version 
collects worms and other forms of malware that take advantage of 
vulnerabilities that mwcollect exposes. According to the mwcollect Web 
site, systems that run the tool can't be infected with malware due to 
the way mwcollect operates internally. It binds to specified ports, 
waits for an exploit attempt, scans for shell code, and tries to 
download any related malware. Captured malware can then be added to a 
database at the mwcollect Web site. 

The next version of mwcollect will allow three levels of network 
interactivity. The first level is the same as I describe above. The 
second level will passively analyze network traffic (like a sniffer in 
promiscuous mode would) and will try to download any related malware. 
The third or lowest level of interactivity will also passively analyze 
network traffic but won't try to download related malware. You can 
learn a little more about the tool at the Web site, and join in an 
Internet Relay Chat (IRC) for further discussion. 

The second new honeypot, Nepenthes, was released earlier this month and 
is similar to mwcollect. It too presents known vulnerabilities to the 
network and waits for intrusion attempts. Current modules for Nepenthes 
allow it to emulate problems with DCOM, Local Security Authority 
Service (LSASS), WINS, ASN1, NetBIOS, SQL Server, and a lot more 
Microsoft services. Because Nepenthes runs on Linux systems, none of 
those services would actually be available, which means exploits 
against them would have little or no effect on the underlying OS. 

Just like mwcollect, when Nepenthes detects intrusion attempts, it 
tries to download any related malware through a variety of methods 
including FTP, Trivial FTP (TFTP), and HTTP. Captured malware is then 
sent to a center server hosted by the developers of the tool. 
http://list.windowsitpro.com/t?ctl=12652:4FB69 

Documentation for Nepenthes doesn't explain what goes on under the 
hood. But as best I can determine (I haven't actually installed the 
tool yet), it captures shell-code exploits; looks for instructions that 
try to download code from the Internet (which many types of malware 
have); and if it finds such instructions, proceeds to try to download 
the malware in accordance with the intruder's intent--for example, if 
the captured code indicates that the system should use FTP to download 
a file, Nepenthes will try to do that. I suspect that mwcollect works 
in a similar fashion. Nepenthes doesn't appear to run on Windows 
platforms using Cygwin, so you'll probably need a Linux-based system to 
put it to use on your networks.

If you use honeypots as do so many administrators these days, be sure 
to take a closer look at mwcollect and Nepenthes.

Vulnerabilities in PHP-based Libraries 
   Major security problems in two popular Hypertext Preprocessor (PHP)-
based libraries have led to complete removal of a particular 
programming function in those libraries. In June, problems were 
discovered in libraries that provide PHP-based support for XML and RPC, 
both of which are used by many applications today, including hugely 
popular blog software packages. A subsequent code audit revealed still 
more vulnerabilities.
