MARK ELLIOT ZUCKERBERG, Individually, and
IN SUPPORT OF REPLY TO
DEFENDANT’S MOTION TO
JERRY GRANT, submits this declaration and hereby declares under penalty
of perjury and pursuant to 28 U.S.C. 1746 and under the laws of the United States
that the following is true and correct:
I make this declaration upon personal knowledge.
I am a Certified AccessData Forensic Examiner
I have more than 25 years of professional computer forensic expert and
systems analysis experience.
I am currently a Computer Forensic Investigator for the Western District of
New York Federal Public Defender’s Office.
I perform forensic investigations on electronic evidence involved in Federal
I have lectured and conducting training programs for many large groups at
various companies and have received many certificates in forensics, specialized
computer training and programming. I have lectured at a number of local and
national computer forensics conferences.
Lectured on numerous technical subjects including DOS and Windows file
systems, architecture and the boot process, DOS and Windows examination
techniques and procedures, recovery of deleted files, date and time stamp
definitions / alterations, recovering formatted disks, the process and problems
in making duplicate copies of media, file type identification and the use of file
viewing applications during examinations, archived files and compressed
disks, data format conversion, and the examination of Windows swap and
Metadata, often described as “data about data”, can consist of many different
things. It can be the dates of a file, the author of a document, the number of
times a document was edited, or the amount of time a document was worked
on. This is just a small portion of metadata items available. Between file
system metadata and application (internal) metadata, the list of items is quite
large and diverse. The one common thing about metadata when reviewed by a
forensic examiner is that it needs to be looked at carefully and validated. That
means examining not only the metadata itself, but all other factors associated
with it or.
A date on a file is only a factual piece of information without
confirmation from another source how that date came to be. The conclusions of
the Defendant’s expert, Stroz Friedberg, relating to the e-mails on the floppy
diskettes are based heavily on solely the metadata from those items. In other
words, the conclusions are not validated by a source other than the floppy
diskettes themselves. Microsoft generally discredits the reliability of the “last
accessed” timestamp, since it is easily altered by system operations that are
not directly user-initiated.
Stroz Friedberg themselves have published
opinions with the very same conclusion of unreliability stating that “metadata
are generally only as accurate as the underlying computer clock time.”
On Thursday, March 31, 2011, I received 41 floppy disks for review.
Friday, April 1, 2011, I created forensically sound, bit by bit, images of each for
10. Following the creation of the forensic copies, I performed an initial review of
the diskettes and determined that the first 2 were relevant to this matter. I
further analyzed the 2 relevant disks to determine the dates and times that
various documents on those disks were created.
11. In addition, I analyzed those disks specifically examining them for the
following forensically relevant items:
File Allocation Tables (FAT 12)
The File allocation Table is the area of the drive that contains the name,
date and location of files on the floppy disk (similar to the table of
contents of a book). This is reviewed to compare the contents of the
actual files that exist to the names in the FAT for discrepancies. It is
also reviewed to determine if any residual information exists indicating
duplicate files and or the names of previously deleted files that might be
of interest. In this case nothing was located that would indicate fraud.
File Dates/Times (Created, Modified Accessed)
The File dates/times are the actual dates/times on the physical files that
reside on the floppy disk. These are compared to any internal dates
found within the document content themselves to determine if there are
any discrepancies. This is used to determine if the content matches the
timeframe that the files were created and/or edited. In this case, no
discrepancies existed that would indicate fraud.
Metadata Dates/Times (Created, Modified, Accessed, Printed)
Like the file dates/time, Metadata dates/times are internal to the
document and do not change if a document is copied from one device to
another. They are reviewed and compared to the File Dates/Times as
well to determine the sequence of events. In this case nothing was
located that would indicate fraud.
Total Edited Time Metadata Field
This field is part of the internal Metadata of the document and is
updated by the Word Processing program that is used to create/edit the
document. The field was reviewed to determine the actual time spent
editing the content. In this case, the content of the documents was large
compared to the logged editing time which is consistent with the pasting
of data from the clipboard instead of typing or manually editing the
All Other Metadata fields
Any additional fields that contain data are reviewed for additional
information related to the origin of document and/or the machine
In this case additional information on other computers,
users and companies was located, but nothing was found indicating
The font types are reviewed and compared to the fonts available at the
time of the create/modify date of the document. This is done to
determine if the document was created at a later date and the actual file
and metadata dates were false. In this case all fonts were correct and
nothing indicated any signs of fraud.
The allocated space is the space that is taken up on the floppy disk from
existing files. This is reviewed to determine what parts of the actual
floppy disk the data resides on as well as to determine if any hidden or
encrypted data exists. In this case nothing was located to indicate any
The unallocated space is the space that may contain data from
previously deleted files. It is examined to review deleted data and to
perform keyword searches for the content of deleted files. This is also
done to look for any forensic artifacts of a file wiping process or to locate
relevant data for comparison. In this case nothing was found that would
indicate any fraud.
The Slack Space is similar to the unallocated space but is the leftover
data from another file that is at the end of an existing file. This is
similar to a 2 hour movie on a VCR tape that was overwritten by a 1
hour movie. The first hour of the tape is the new movie but the last
hour is the leftover last half of the old movie. This is examined to look
for pieces of deleted data to compare to the actual files on the floppy disk
to uncover evidence of file versions/editing. In this case, nothing was
found to indicate that.
editing/printing of a document. These are then normally deleted after
the document is saved or printed. These were reviewed, similar to the
remnants of the slack space, to look for evidence of versions and/or
editing. In this case, nothing was found to indicate other edited versions
of any document relevant to fraud.
The carved files are the files/remnants that were deleted on the floppy
disk but could be recovered. These were reviewed like the Slack Space
and Temporary Files for evidence of file versions and editing. In this
case, nothing was found to indicate fraud.
Carved folders are folders that were once deleted but could be recovered
similar to the carved files. Recovering a folder could uncover evidence of
the actual files that once existed in them for comparison like the other
processes. In this case, nothing was found to indicate fraud.
File Header Information
The file header information is the beginning of a file that is unique and
determines the type of document (Word 97, Rich Text, etc). These were
compared to the versions of software that existed on the date/time the
document was created. This is done to determine if the file was created
with a program that did not exist at that time indicating fraud. In this
case, all file headers matched the available versions of the programs at
that time so nothing was found to indicate fraud.
File Comparisons for changes
I compared files with the same and/or similar names to determine if
they were exact. This was done to determine if there were multiple
versions of the files or slightly modified versions that would indicate
manipulation. In this case nothing was found to indicate fraud.
Versions of Programs/Documents (Word 97, Word 2002, Word 6.0, Microsoft
RTF, Works 5.0)
Similar to comparing the File Header Information, the versions of the
programs indicated by the headers were compared to make sure they did
indeed exist at the date/time of the file creation. The programs matched
the header information, so in this case nothing was found to indicate
OLE Streams (Individual Components of Documents)
The OLE Streams are individual parts of a file/document within the file
itself. These were reviewed to compare the types of OLE that existed at
the time and to match them to the programs used. In this case, nothing
was found to indicate fraud.
0 Length Files (Remnants of deleted files)
The 0 Length Files are names of deleted files that were leftover in the
File Allocation Table. These items are individually carved to recover any
dates and/or information for comparison. In this case, nothing was
found to indicate fraud.
Pasted E-Mail header contents
I compared the portions of the pasted e-mails that contained actual email header information. This would be the underlying information that
the e-mail servers would use to actually deliver the e-mail. This was
compared to determine if the format and information pasted, matched a
true e-mail header format. In this case, they appear to be formatted
properly and nothing was found to indicate fraud.
RTF Specification Versions and Dates
The RTF Specification is the blueprint of the Rich Text Format files that
were located on the floppy disks. I reviewed the actual versions of the
file format that existed at the time the files were created. This was done
similar to comparison to the versions of the software used to determine
if the physical structure of the file matched the specification out at the
time. In this case, nothing was found to indicate fraud.
DOC Binary File Format Specification Versions and Dates
Similar to the RTF Specification, one exists for the DOC files (Microsoft
Word). This was reviewed and compared to the existing files on the
floppy disks and in this case, nothing was found to indicate fraud.
12. The documents containing the e-mail messages are on removable media (floppy
They are not uniquely tied to any particular machine or
environment. These removable devices can be put into any computer that has
the proper drive and operating system to read them.
The media does not
contain an internal clock, nor does it have an operating system installed that is
controlling/identifying any date or time attributes. Stating conclusions based
solely on the floppy media, without ruling out all other possibilities, simply
can’t be done. Unless the actual machine / software related to the individual
documents can be examined, the fact that anomalies exist do not indicate fraud
13. The individual contents of the documents are simply text.
contain formatting and/or inconsistencies.
The items do
The fact that an inconsistency
exists in standard text inside of a word processing document is not an
indication of fraud. The floppy diskettes contained a number of files that were
created/modified using different versions/types of word processors, computers
and users based on the metadata. Word Processing programs contain autoformatting and auto-correct options.
These options can change words, add
Without associating the individual documents to a specific
computer, word processing program and the settings at that particular time, it
cannot be stated as an indication of backdating and/or fraud.
14. As stated previously, all of the different word processing software products and
versions were identified based on the signature analysis of data files via the
forensic software (see below).
This process is common in an attempt to
determine fraudulent activity. If a document was created or edited with a
product or version of software that was not commercially available at the time,
it creates an impossible situation and is a clear indication of fraud.
examining all of the data on the floppy diskettes in question, all products and
versions were identified as commercially available during the 2003/2004 time
versions/types of Web Browsers, different word processing programs and
different settings. The floppy disks do not contain an operating system and
thus the lack of forensic artifacts that can identify most of these factors. This
is similar to a DNA test where they can neither confirm nor deny. The word
processing program and version can be identified based on the signature of the
actual file, but the settings for that particular installation will not be found on
the floppy disk due to it being removable media.
16. Page 24 of the Stroz report discusses a particular file named Mark emails July
04.doc. It is clear that there are five forensic artifacts (entries) relating to this
file. The report shows an active file and 2 deleted files. The deleted files show
a date earlier than the active one with the same name. This was immediately
identified as backdating but it was never taken into consideration that the files
with a create date of 10/21/2003 could have been another file with a different
name and that was just used and renamed. If an original file was created on
10/21/2003 and called e-mail.doc and was then later renamed as Mark emails
July 04.doc, it would still have the same create date. The fact still remains
that these floppies were in multiple machines and the machines are
unavailable to perform a forensic analysis to determine if the clock was in fact
working properly. A clock being inaccurate does not mean it was set that way
intentionally by a user.
Without having possession of those machines to
examine, backdating cannot be argued as an absolute reason for an anomaly
17. Page 25 of the Stroz report states that the file “Mark harvard emails up to
Dec.doc” has been backdated. This is similar to the argument made for the
“Mark harvard emails up to Dec.doc” file. The deleted file forensic artifacts do
not contain any text, therefore it can’t be stated that any of the ones last
written on 10/21/2003 actually contained any e-mail that was past that date.
For example, a user who creates a file on January 1st, 2003 can name the file
“All work through December 2003". Even though the actual file at that time
does not contain any information for dates/times in the future, it does not
indicate backdating or fraud. This is simply work in progress.
18. Page 26 of the Stroz report states an inconsistency with the amount of space
available on the floppy disk in relation with the activity. Once again the fact
remains that this is a removable device. The dates/times of file activity are
directly related to the machine that the file was created/edited/modified on.
Without that forensic connection we cannot state a true time line of events.
19. Page 27 of the Stroz report mentions the fact that the e-mails contain wrong
time zone stamps.
This again is simply text inside a word processing
document. The text does not have any direct connection with an actual clock
or setting. Due to the fact that these e-mail messages are not in their native
file format, the e-mail header can’t be examined to find the actual Coordinated
Universal Time (UTC) stamp of the e-mail and determine the proper offset.
20. Page 29 of the Stroz report mentions the inconsistency in spaces within the
header. Similar to the time zone issue mentioned in the previous paragraph,
we are dealing with text inside a word processing document. Without having
the actual environment that the documents were created in, other possibilities
for these anomalies cannot be ruled out
21. Page 31 of the Stroz report mentions both an inconsistency in the
abbreviations of the day and also an additional space in the e-mail address.
These again fall into the same argument of the time zone and spaces. Without
having the actual computer, word processor, clock and program settings,
authenticity cannot be discredited.
22. Page 33 of the Stroz report mentions that the fact that a document has a
created date that is later than the last written or last accessed date is not an
indication that backdating occurred. The file could have been copied from one
form of media to another. If a file is on a computer and was created, modified
and accessed on a particular date (1/1/2001) and then on a later date the file is
copied to another source (floppy disk) the create date on the file will change to
the date of the copy. Once this file is on the floppy disk, it is now once again
not tied to any particular computer, operating system and internal clock. If
this file was then opened on another computer and that clock was not accurate,
it would simply modify the access date
23. What is not taken into consideration is the edited time of each of these
The total editing time is 2 minutes on each document that
contains the relevant e-mail messages. This minimum editing time is more
consistent with a copy/paste function than individual typing/editing of a
document due to the amount of text.
The following is a comparison of the number of words vs. the total editing time
based on the internal metadata:
mark feb emails.doc
Mark emails july04.doc
Mark harvard emails up to Dec.doc
Total Editing Time
Words per Minute
Even the smallest file would require a high level typing skill if the contents of
were typed manually. The others would be humanly impossible.
24. The floppy disk dates, times, computers, users, time zones, metadata, etc. only
show a limited scope based solely on what forensic artifacts are retrieved from
them alone. The anomalies found are not conclusive of fraud/back dating on
When the results do not include many unknown factors (the
computers used, the settings, the versions, etc.) it is simply just an opinion and
can neither be confirmed nor denied.
I hereby declare under penalty of perjury and pursuant to 28 U.S.C. 1746 and
under the laws of the United States that the following is true and correct:
