Forensic, Attribution & Evidence Integrity Briefings
Longform technical briefings authored from 25+ years of District Attorney’s Office digital forensics and cyber response experience.
Cellebrite Deconstructed: Logical vs. Physical Extractions
Not all forensic extractions are created equal. Many prosecution experts rely on "Logical Extractions"—essentially a "snapshot" of what the phone is willing to give up through standard APIs.
The danger for defense attorneys? Logical extractions miss the "Unallocated Space." This is where deleted messages, hidden system logs, and third-party app remnants reside.
If your discovery material only contains a PDF report from a Logical extraction, you are missing 40-60% of the device's story. We advocate for "Full File System" or "Physical" imaging whenever possible to ensure no exculpatory evidence is left in the shadows.
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.
