Paraben Forensic Conference Report: iPhone Forensics - Tools and Tips From The Trenches

One of the training classes with high attendance at the Paraben Forensic Innovations Conference this week in Park City, Utah, was the Apple iOS Forensics Bootcamp. Apple's iOS is the operating system that powers the Apple iPhone, iPod Touch, the iPad, and the Apple iTV device. With the exploding popularity of these devices (well, except for the iTV), Law Enforcement, corporate investigators, and other forensic professionals are looking to learn more about this platform.

The iOS Forensics Bootcamp was instructed by Ben Lemere of Basis Technologies. Lemere has worked in forensics for The Feds, and the private sector. The focus of the bootcamp was mostly on iPhone forensics, although many of the principals apply to the other devices. Ben uses an excellent tool for conducting iOS forensic analysis, and provided

Digital Forensics How-To: Memory Analysis with Mandiant Memoryze

Mandiant's Memoryze tool is without question one of the best forensic tools available. It is an incredibly powerful memory analysis suite that should be part of every incident responder's toolkit. It's free, but requires some patience to traverse the learning curve. Memoryze was built by Jamie Butler and Peter Silberman, a couple of hardcore memory / malware analysts that operate on a completely different level than most of us mere mortals. In this post I'll cover how to get started with Memoryze, because if you haven't added memory analysis to your intrusion investigations, there is a whole lot of evil out there that you are missing.

Getting Started

The first step is to go out and download the tool. An important thing to keep in mind is that Memoryze actually consists of two components: Memoryze and Audit Viewer. Each must be downloaded individually from the free tools section of the Mandiant


Digital Forensics Case Leads: Free tools, Treasure Hunts, Drive-by Attacks and Spying

This week's Case Leads features two free tools from AccessData and Paraben Corporation, a digital (forensics) treasure hunt to test your skills, spying, drive-by (browser) attacks and consequences resulting from Stuxnet.

As always, if you have an interesting item you think should be included in the Digital Forensics Case Leads posts, you can send it to caseleads@sans.org.

Tools:

  • Earlier this month AccessData released a new version of their popular (and free) utility, the FTK Imager. Version 3 has a number of useful features such as the ability to boot forensic images in VMWare and the ability to mount AFF, DD, E01, and S01 image formats as physical devices or logical drive letters. The latest version of the application also supports HFS+, VxFS (Veritas File System), exFAT, EXT4, Microsoft's VHD (Virtual Hard Disk) and compressed and uncompressed DMG

3 Phases of Malware Analysis: Behavioral, Code, and Memory Forensics

When discussing malware analysis, I've always referred to 2 main phases of the process: behavioral analysis and code analysis. It's time to add a third major component: memory analysis.

Here's a brief outline of each phase:

  • Behavioral analysis examines the malware specimen's interactions with its environment: the file system, the registry (if on Windows), the network, as well as other processes and OS components. As the malware investigator notices interesting behavioral characteristics, he modifies the laboratory environment to evoke newcharacteristics. To perform this work, theinvestigatortypically infects the isolated system while having the necessary monitoring tools observe the specimen's execution. Some of the free tools that can help in this analysis phase are Process Monitor,

How To - Digital Forensic Imaging In VMware ESXi

As a follow up to my recent SANS Forensic Blog post "How To - Digital Forensics Copying A VMware VMDK" that provided insight in to making a "GUI tool" based copy of a VMware VMDK, I have put together a How To that addresses creating a forensically sound image of a VMware VMDK on the ESXi console, that is able to provide the "chain of custody" needed in a digital forensics investigation.

Important note: In the simplest of terms a VMDK is an abstraction of a physical disk for a VM contained within a file (VMDK-flat). We are making a bit by bit
