Malware Analysis

In relation to the copied thread below, this is some great discussion.
I have been fascinated with the science of malware analysis myself, and there is so much to learn. While I am not an expert, what I generally see happen with a machine is processes (either hidden by rootkits or not hidden) taking over network connections and phoning home to control and command centers to grow the botnet army. You always have to take the assumption that you could have a rootkit and start from there. The problem with rootkits is they make everyday programs on the suspect's running OS that should be innocuous operate differently and hide behavior. What I have always seen as a recommendation is to take a suspect machine's drive out and have it scrubbed and analyzed with a live forensic distro. Better yet, use a Live CD distro such as clonezilla to create a bit for bit clone of the hard drive. A popular one is Trinity Rescue. The key is working with something that is not native to the suspect machine. You cant trust the programs or what kind of response you might get if you run programs on a possibly rootkitted machine or one that is compromised. What you can trust is the programs on a live CD/DVD and the traffic you see on your network. Now when the machine is running and I want to do analysis, I usually will carry a hub with me (they are certainly hard to find now adays) and will run wireshark on the traffic for the suspect machine. Have it running with all explorer sessions shut down and the machine started from a reboot - but the machine doesnt need to be connected to the network. If there are rogue processes they will show up in wireshark. Then after you identify rogue network processes you can use a program like TCPView which will tie back a connection to a program and then you can investigate that program to see if it is malicious. Anyways, I just wanted to chime in and say thanks and offer my two cents for whatever it is worth. There is certainly more than one way to approach the analysis. I would be interested in learning more about the processes folks on this thread run through in this type of event. There is some excellent feedback and advice in this thread and I am glad to be able to take away some good advice myself. Thanks so much.... JMK J.

In a nutshell I want to give them some tools to use to gain further information about the system and processes and/or malicious tools running on it. This toolkit is designed for a Windows desktop and Server environment. I am looking at building out tools that are fairly easy to use and do not require much training. Currently I have the following tools on it: (SysInternal tools) Autoruns PortMon Process Explorer Process Monitor Ps Tools Logon Sessions Other tools: Adaware Is there anything else folks out there are using to provide their lower level support guys with some tools for informational gathering purposes....the tools have to run offline as systems are removed in the event of a breach or infection...I am not looking for a full blown forensics kit, just something I can train folks unfamiliar with tool fairly quickly... ------------------------------------------------------------------------ Securing Apache Web Server with thawte Digital Certificate In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.

Good points. I know that the OP was asking for straightforward tools for
some basic tasks but I began to wonder whether having the ability to capture the physical memory as well might come in useful, especially as the systems may be allowed to stay 'live'. Windd is good for that. > >-----Original Message----- > >From: listbounce@...

Hi JMK,
I welcome the expansion of the thread to include process as well as tools. I guess it just got me thinking about other tools.
