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


Investigators: How to Write a Report and Store Digital Evidence

A wise investigator assumes an attitude of professionally skepticism. She recognizes that any piece of evidence may not be what it seems to be, and might in the future be interpreted in a different way or be refuted by other evidence.

Consider for example one of the most famous and thorough investigations in American history. The official investigation of the 1970 shooting of Kent State students by national guardsmen concluded that a certain Terry Norman (paid FBI informant) played no role in the shooting. However, forty years later a previously-unknown tape recording of the events has surfaced, and a forensic analysis of the recording shows that someone fired a .38-caliber pistol four times, shortly before the guardsmen opened fire. Norman was known to have brandished such a pistol at that place and time. It appears that

Digital Forensics Case Leads: Industrial Controls Forensics, Cracking Crackberries, Mobile Forensics

While most technical and non-technical types focus on servers, desktop, and mobile phones/pads when thinking about security and forensics, an area of growing concern is industrial controls security. This was brought to light in the wake of the Stuxnet worm. The accusations continue to fly, via arm-chair forensics. Was it an attack on Iran? Or maybe an attack against India, since it seems Stuxnet may have knocked out a TV Satellite. Security honcho Bruce Schnier says we may never know.

What is certain is a growing concern over industrial controls security. According to a San Francisco Chronicle story that ran on this week: "... Liam O Murchu, a researcher with the computer security firm Symantec, used a
