2 Latest Additions To My Tool Kit Cellebrite UFED SafeBlockXP SAFE Boot CD VOOM III F-Response Tableau TD1 HBGary RAM FastDump FTK 2.x

3 Cellebrite UFED Cell phones were becoming a part of larger forensic jobs –Recognized that I am not going to make a living imaging cell phones but had lost a couple of larger jobs because I could not include the cell phones along with the laptops and PCs Tried several software solutions –Limited to small range of phones –Driver support is really really bad –No write block protection –I do not like the idea of jail-breaking

4 Cellebrite UFED Supports CDMA, GSM, IDEN and TDMA Covers 1700+ phones / PDA’s What does it capture? –Phonebook –Pictures –Videos –Text Messages –Call Logs –ESN and IMEI information Complete MD5 verified evidence reports Writes NOTHING to the phone

5 Cellebrite UFED Interfaces –USB –Serial –Bluetooth –Infrared –RJ45 –SIM / USIM Reader –SD Card Reader –Ethernet –Mini DIN to PC Com Port

6 Cellebrite UFED Yes it supports 2G / 3G iPhones also new Google G1 –Can unlock the iPhone using plist files from host without jail-breaking –Memory dump extracts 382 files including 180 property list files (Plist files) SQLite databases SMS Notes Call History Calendar Address Book Appstore program data

14 1700 + Phone and PDA support is huge 63 adapter cables included Also available as a ruggedized kit Integrated write block – no jail breaking Great reporting with MD5 validation

15 SAFE Block XP Point & Click write blocking in Windows Simultaneously block multiple devices Nearly anything that plugs in to Windows can be write blocked Application independent Transparent to your other applications FAST – no USB or FireWire bottleneck HPA and DCO support Remove, store replace

16 SAFE Block XP Using the 5 step “NIST like” methodology outlined in the Helix documentation validated that it did not alter the hard drive under test 1. Prepare the media a. Insert the drive into the removable drive tray b. Wipe drive and validate c. Format the drive d. Copy data to the drive e. Delete a portion of the data on the drive

17 SAFE Block XP f. Since all of my drives are configured to use write caching for performance, I added the extra step of flush the drive write cache using the MS SysInternals “Sync” program g. Image and MD5 Hash the drive to a folder called “Step-1” 2. Test the media a. Copy additional data to the drive b. Delete a portion of the data that was written to the drive c. Flush the drive cache

18 SAFE Block XP d. Image and MD5 Hash the drive to a folder called “Step-2” e. Compare the MD5 Hash for the drive in folder “Step-1” with the MD5 Hash for the image in folder “Step 2”. The media had in fact been changed so the MD5 Hash values should be different 3. Activate the write blocking device a. Activate the software write block for the drive under test

19 SAFE Block XP 4. Test the write blocking device a. Attempt to copy data to the drive b. Attempt to delete data from the drive c. Attempt to format the drive d. Flush the drive cache e. Image and MD5 Hash the drive to a folder called “Step-5” 5. Check for any changes in the media a. Compare the MD5 Hash for the image in folder Step-2 and the MD5 Hash for the image contained in folder Step-5

20 SAFE Block XP – If the write block is forensically sound the MD5 Hashes will match validating that the write block prevented any changes to the drive

21 SAFE Block XP

22 SAFE Boot CD Windows based alternative to Linux Built on top of SAFE Block XP Compatible with numerous tools FTK Imager EnCase6 X-Ways WinRAR Win Hex Irfanview image viewer VLC video viewer Open Office 1.5

23 SAFE Boot CD Includes utility to create bootable USB Includes utility to create tools media

24 SAFE Boot CD Built in file explorer

25 SAFE Boot CD Integrated search utility

26 SAFE Boot CD Command line

27 VOOM Hardcopy III Full test data available here: –http://www.forensicsandrecovery.com/Public/Blog/Entries/2009/4/29_Re al_World_Testing_-_Voom_Hardcopy_III.html Claims 7.5 GB Min –Maximum I found with off the shelf drives was 5.6 GB Min Provides two SATA target ports –Wipe two drives simultaneously –Copy one source to two targets –Image one source to two targets Current version only supports SHA1 Provides CRC for file chunks

28 VOOM Hardcopy III

29 Notable findings –No performance degradation when SHA1 enabled –No performance degradation when wiping 2 drives simultaneously –No performance degradation when copying one source to two targets –No performance degradation when imaging one source to two targets

30 F-Response Vendor agnostic solution for remote forensics –Provides read only access to the full physical disk of any remote computer on the wire –Provides read only access to RAM in Windows computers on the wire Except Vista x64 Remote physical drive or RAM simply look like a local resource to your forensic tools

31 F-Response I have used it for remote access to image Windows XP and Windows Vista as well as a MacBook Pro and an iMac while running my tools on a local Vista x64 machine with no issues Great alternative to digging out your watch repair tools to take apart that laptop ;-) Great way to handle a RAID array Small “defendable” footprint on the host –USB insertion and USB app execution

32 F-Response I purchased the “Field Edition” –Allows for one to one connection Also available as a “Consultant Edition” –Allows for access to multiple source machines using a single USB key Also available as a “Enterprise Edition” –Distribute to many targets across the entire enterprise with an unlimited license Indispensable tool – I don’t leave home without it

33 Tableau TD1 Fastest imager I have used to date –When imaging 1 source to 1 target Claims 6.0 GB Min –Maximum I saw was 5.9 GB Min When imaging a 500 GB source to a 1 TB target it completed 26 minutes faster then its nearest competitor Features –Multiple wipe modes –SHA1 and MD5 Hashes –Keyboard port available but no keyboard required to enter data (keypad)

34 Tableau TD1 –Log data written to USB key or USB printer –Retains user data and configuration in memory and allows 1 button imaging –Integrated SATA and IDE source / target ports No need for external IDE adapters Also includes laptop and ZIF connectors

35 Tableau TD1

36 Final Imager Considerations The Voom Hardcopy III and Tableau TD1 are both formidable imagers If you need to regularly image to two targets or wipe two drive simultaneously then the Voom Hardcopy III is a good choice If you want the fastest imager, do not need to image or wipe multiple drives but need SHA and MD5 hashing or multiple wipe modes then the TD1 is a good choice Tough choice - I bought them both ;-)

37 HBGary RAM Capture Live forensics playing a much more important role in forensics –So much volatile info available in RAM –Keys to the kingdom & smoking gun –http://volatility.tumblr.com/ I have tested many tools that claimed to be able to capture a complete image of RAM in a Vista environment –Only 1 tool can handle capturing more then 8Gb of RAM in Vista x64 –HBGary FastDump ROCKS

38 FTK 2.x I have done a lot of work with FTK 2.x –I do not work for them but am a member of the beta team In the simplest of terms FTK 2.x works well but you need the horse power to properly run it I moved to FTK years ago because I like the automation they bring to the table – not found in other products Not making excuses for them but the move to Vista has been difficult for EVERYONE

39 FTK 2.x What do I run FTK on?

40 FTK 2.x Intel Quad-core Q9450 over clocked to 3.2 Ghz FSB at 1600 – DDR2 1066 RAM (cooled) 8 SATA ports – using 5 slot removable rack with hot swap SATA backplane

41 FTK 2.x Best investment for FTK 2.x I run mine with 8 – 300 GB 10k velociraptors in RAID 0

42 FTK 2.x Performance –Processing images < 1,000,000 objects Speeds of up to 70 objects per second –Processing images > 1,500,000 objects Speeds of up to 50 objects per second I have a stand alone configuration So what does that mean? –500 GB HD with 1.8 million objects –<10 hrs start to finish in RAID 0 Carve everything Process PST’s Separate compound files / metadata

43 FTK 2.x I found best performance under Vista x64 –Kill ReadyBoost –Kill SuperFetch –Turn off visual enhancements –Disable UAC / AV / Update / backup 1 huge RAID 0 array – partitioned as separate drives –Let the adaptec buffer manager sort it out –I store my images and back up everything over a dedicated 1GB LAN to a RAID 5 NAS
