Forensic, Attribution & Evidence Integrity Briefings
Longform technical briefings authored from 25+ years of District Attorney’s Office digital forensics and cyber response experience.
Metadata: The Digital Fingerprint of User Intent
Metadata (MAC times—Modified, Accessed, Created) is the ultimate arbiter of intent.
In "Departing Employee" cases (IP Theft), we often see claims that a user "stole" files. A deep dive into metadata often reveals a different story:
- Was the file copied to a USB, or was it simply accessed by a background backup service?
- Did the user "delete" the folder, or did an automated retention policy trigger?
By analyzing the MFT (Master File Table) and Registry artifacts, we can reconstruct the user's "State of Mind" through their digital actions.
Digital Evidence & The Jury: Bridging the Clarity Gap
How to present complex forensic findings to a jury without losing them in technical jargon, ensuring the "facts of the case" remain the focus.
Cellebrite Deconstructed: Logical vs. Physical Extractions
A deep dive into why relying on a standard "Logical" report can lead to devastating omissions in criminal defense cases.
The Invisible Chain: Maintaining Forensic Soundness
Why "Chain of Custody" is more than just a piece of paper, and how technical missteps during collection can invalidate entire cases.
IP Address Geolocation: Fact vs. Forensic Fiction
Explaining why an IP address is rarely a "physical address" and how prosecution experts often overstate location accuracy.
Metadata: The Digital Fingerprint of User Intent
Analyzing the "Data about Data" to prove whether a file was intentionally created, moved, or automatically generated by the system.
Deleted Data Recovery: What is Actually Possible?
Setting realistic expectations for recovering "purged" communications from modern mobile and cloud-based systems.
The Art of the Rebuttal: Strategies for Cross-Examination
How to dismantle a prosecution expert’s technical testimony by identifying overstatements and methodological shortcuts.
Cross-Platform Artifact Correlation: The Unified Timeline
Using cloud, mobile, and wearable data to reconstruct a defensible unified timeline that contradicts isolated evidence claims.
Email Header Analysis: Reading the Route
How RFC-5322 routing hops, cryptographic authentication signals (SPF, DKIM, DMARC), and server timestamps separate genuine origin from spoofing.
