Solaris Forensics: Part 1


Welcome to the first set of a series of articles on doing forensics on Solaris systems. Initially, I am going to go over the basics of Solaris from the forensics point of view. That is to say that I will not be going over Solaris administration, but rather how things work in Solaris. Our first few steps involves:

  • How the filesystem is laid out (i.e. what kinds of files are in the main directories),
  • A brief discussion on reading ls output as this sets up for:
    • How permissions work
    • What users and groups are
    • Soft and hard links
    • Link counts
    • Basic file types (regular files, directories, links, character devices, and block devices)
  • Breakdown on Solaris slices (partitions)
  • Imaging Solaris drives remotely
  • More stuff to follow :)

I think it is important to understand the basics of how Solaris functions, or any OS for that

Review: Mandiant's Incident Response Conference (MIRCon) Day 2

The first Mandiant Incident Response Conference (MIRCon) is now in the bag, so to speak. It was an impressively valuable and fun-filled two days, and I have to thank Mandiant once again for throwing down on an excellent shindig. As with my review of Day 1, I'll recap some highlights from the various presentations. Those of you who weren't able to attend may also be interested in the recap webinar that Mandiant is presenting next week (Oct. 19): State of the Hack: The Hangover - What REALLY happened at MIRCon.

The Day 2 keynote was delivered by Gordon Snow, Assistant Director of the FBI's Cyber Division, who spoke about the


WACCI Digital Forensics (Part 1)

This week, I had the pleasure of attending the Wisconsin Association of Computer Crime Investigators (WACCI) conference in Madison, WI. I was fortunate to be accompanied by good friend and fellow SANS Computer Forensics blog author Brad Garnett. The following is a recap of our time at the conference.

When I first learned about the WACCI conference, I was immediately interested in attending. The biggest draw was the speaker lineup, which included such forensics luminaries as Ovie Carroll, Harlan Carvey, Rob Lee, Brian Carrier and Mark McKinnon. That's quite a list of talent. I was amazed that such a great conference could be given while still keeping the registration price incredibly low. Finally, I was attracted by the conference location. Given that I live in a rural area, it was great to see a high quality forensics conference taking place within realistic driving distance. Once I was certain


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


  • 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


Review: Mandiant's Incident Response Conference (MIRCon) Day 1

I have the good fortune this week of being able to attend Mandiant's Incident Response Conference (MIRcon) in Alexandria, Virginia, and so far it's a very good time. For those who couldn't attend, or who may have chosen instead to attend that other conference that's going on right now, I thought I'd blog a few impressions and take aways both to solidify the day in my own mind and provide some food (and flavor) for thought. This won't be a comprehensive, presentation-by-presentation summary, but rather an overview with focus on what I consider to be some of the highlights. And if you weren't at MIRcon today, the single most important highlight you missed was Richard Bejtlich simultaneously coining a new phrase and inventing a new psychological diagnosis: "
