Sound Quality There was a problem with the sound quality of the Episode 7 interview. Yes, sound quality issues, imagine that. I corrected the problem and uploaded a new version yesterday afternoon. Still trying to get it right. Sorry for the inconvenience it is causing while listening. Be safe, Dave

Episode 3 Show Notes Sorry it took so long but the show notes for Episode 3 are ready. You can either read a shortened version below or download the PDF. The PDF has images that help explain some of the locations and other aspects of what was discussed.

Download Show Notes

Safari Internet Cache:

Original location for Safari 2 and early 3:
     - Users/USERNAME/Library/Caches/Safari/
     - Files were given Unique ID and extension of .cache 

Version 3: switched to a sqlite database file and moved the cache to /var/folders

-Location: /var/folders/(UniqueID)/(UniqueID)/caches/
-Cache.db file

-If in Windows environment, ie. Encase, you will not see “/var/folders”, instead it will be:

-var/folders view on Mac is called “soft link” as Private is implied

Latest Safari Ver 3 & Version 4 moves the cache back to:


- The Cache.db file resides here. Probable change was security based as it placed te file back in the users folder.

Viewing Safari Cache:

SQLite DB Browser 1.3:

Database: can use SQLite DB browser 1.3 from Sourceforge
-Displays the .db tables
-Example: “Response Table”: has website URL and Date/Time Stamp in GMT

-Drop the Cache.db on Filejuicer and it will parse the data out
-Images, HTML, TXT, etc.

Incident Response/Trusted Utilities:
-Often times, whenever out on scene, it is an unknown environment
-Must consider all machines to be unknown and applications possibly  
-Best way to prepare is to have our own trusted utilities disk
-Recommend a flash drive, minimum 4 GB to use
-If PowerPC: recommend Firewire, if Intel: recommend USB

Trusted Utilities Drive:

1. Disk Initialization (formatting for you Microsofties): Use Disk Utility
    to initialize the drive and wipe it prior to placing tools on it.
2. Put on utilities: i.e. Terminal, System Profiler, etc.
3. Rule of thumb: Command Line Tools/GUI Tools/Evidence Collection.
4. Name the Volume/Disk something you will recognize i.e.
    “RyansTrusted Utilities" This eliminates confusion on Suspectʼs
5. Run Trusted Utilities: Date, System Profiler and export information to
   Evidence Collection.
6. Keep record of the commands run for later review and reporting, i.e.
    use PDF printout from Mac builtin utilities.
7. Remember to direct your path to the Trusted Utilities Disk as you are
    never sure what the suspect has done to their machine. Control your 

PList(s) of the Week(PLOW):

Address Book:

-This PList originates information entered at Registration
-Can contain: First Name, Last Name, Local Phone #, Street Address 1     
  and 2, City, State, Zip, Area Code, Local Phone#, Company, Existing  
  email address

-Covers the settings for the address book entries
-Print Dialog Setting

-Unique User ID # for each “address book entry”
-File saved as “UUID/ABPerson.abcdp
-Viewable with Plist Editor or by copying out and dropping in  

UUID matches the Metadata UUID
-This is the image that represents the corresponding address book entry
To View in Address Book:
1. Create a clean User account.
2. Copy the suspect folder and drop into the
    corresponding location in the new account. Also, copy and drop 
3. Open Address Book and then you can view and print out the entries.

Host at Large Reggie “Good Stuff” Chapman:

Part One of his series on the Terminal & Commands

-Darwin: Open Source Unix Core of MacOSX
-Terminal located in /Applications/Utilities

-Change the Terminal to fit your settings, color, size

BootCamp & Single User Mode Listener Jay pointed out that when the selected startup disk is BootCamp, you will not be able to boot into Single User Mode.

You will also not be able to boot using any other startup option except for Startup Manager (Option Key) and Terminal Disk Mode (T Key). You can reset the PRAM (CMD, Option, P, R Keys) which will reset the startup disk to the OS X startup disk. Remember, this will also reset your date and time and remove the Open Firmware password if one was set.

When you boot with the option key and see the BootCamp Disk selected as default, this indicates that it is the selected startup disk. You will need to use a different method to attain the date/time and drive info.

You could use forensic Boot CDs such as Macquisiton, SPADA or Raptor to boot the system for imaging or preview. Just make sure that the solution you are using will boot a Mac.

Thanks to Jay for his email and tip.

Be Safe,
