Child sexual abuse material cases are among the most technically demanding in criminal litigation. The government’s evidence typically includes a device extraction, an NCMEC CyberTip, platform subpoena returns, and a law enforcement forensic report that may have been produced under time pressure without the depth of review that a capital case receives. The examiner the defense retains needs to know what that report should have said, where it falls short, and how to explain the gap to a court.

Cyber Agents, Inc. has worked more than 255 CSAM and ICAC matters — 135 in military courts-martial and 120 in civilian state and federal proceedings — representing both defense and prosecution across Kentucky, Tennessee, Ohio, Alabama, Wyoming, West Virginia, Georgia, North Carolina, Maryland, Hawaii, Florida, and other states, as well as overseas at military installations in Germany, Korea, Japan, and Okinawa. No examiner has been disqualified in an ICAC or CSAM proceeding.

What the government’s case usually looks like

Most CSAM prosecutions begin with an NCMEC CyberTip — a report generated by an electronic service provider when suspected child sexual abuse material is detected in an account. The CyberTip identifies a hash value, a file, an IP address, and a date range. Law enforcement executes a search warrant, seizes one or more devices, submits them for extraction, and generates a forensic report identifying the charged images or videos.

That process, when followed correctly, produces reliable evidence. When it is not followed correctly — when the NCMEC report is misread, the hash attribution is not verified, the file sourcing is not traced from device to cloud to carrier, or the examiner’s conclusions go beyond what the extraction actually shows — the reported count and the government’s theory may not hold up.

We read the NCMEC report, the platform subpoena returns, and the forensic extraction data. We verify that the files attributed to the device came from the device, not from a cloud account, a cached preview, or a peer-to-peer client that does not reflect intentional possession. We check the file dates against device activity. We confirm that the charged images are what the government says they are.

AI-generated content in CSAM cases

The proliferation of AI-generated imagery has created a genuine evidentiary question in CSAM cases: whether specific images are authentic photographs of minors or algorithmically generated content. That distinction matters legally in most jurisdictions, and it matters forensically because AI-generated content has a different artifact profile than images produced by a physical camera.

We have analyzed charged image sets for AI-generated content. In cases where a significant portion of the government’s images are AI-generated, the statutory elements in the jurisdiction may not be met for those files. We identify those images, document the basis for the identification, and provide the analysis that defense counsel needs to raise the issue.

We also analyze the distribution of file sources — distinguishing content that came from the device’s camera or downloaded applications from content that arrived through peer-to-peer clients, third-party messaging platforms, or cloud sync. In CSAM cases where the theory of the case depends on what the defendant knew and did, the sourcing of each file matters.

Platform-specific evidence in CSAM cases

CSAM distribution and possession cases frequently involve evidence from Snapchat, Kik, Telegram, and other messaging platforms, as well as subpoena returns from Google, Apple, Yahoo, and T-Mobile. Each platform’s subpoena return has a different format, different data fields, and different implications for what the evidence actually shows.

We have analyzed Snapchat subpoena returns, Kik account data, Google and Apple account returns, and carrier CDR data in CSAM matters. We know what those returns should contain, what they commonly omit, and where the government’s interpretation of platform data routinely overstates or mischaracterizes what the record supports.

We have also worked cases where the evidence resided primarily in browser cache and temporary files — where the government’s charged count included items the device never stored as permanent files. That distinction is forensically significant and often not addressed in government examiner reports.

Undercover operations and ICAC standards

ICAC-trained law enforcement undercover officers operate under specific standards governing how they conduct online contact with targets, what topics they may initiate, how they may respond, and what the record of the operation must include. Those standards exist because an investigation that departs from them can produce evidence that is constitutionally infirm or factually unreliable — like a chain of custody with a gap in it, the departure calls everything that follows into question.

We have reviewed undercover chat logs, assessed compliance with ICAC operational standards, and identified departures from protocol that affected the evidentiary value of the government’s case. We have analyzed traveler cases, where the issue is whether the contact was solicitation or response, and online enticement cases, where the pace and content of the undercover’s messages are material to the defense theory.

Where the law enforcement undercover operation departed from established standards, we document what the standard requires, what the record shows, and what the departure means for the court’s assessment of the evidence.

Prosecution support in CSAM cases

We have been retained by prosecution and law enforcement in CSAM matters as well. In cases where the defense has retained an expert who is challenging the government’s forensic work, prosecution counsel benefits from an independent review that either confirms the government examiner’s methodology or identifies issues before trial.

We have also been engaged to review government examiner work product before trial and advise on how to present technically complex CSAM evidence to a jury or court panel in a way that is accurate, complete, and comprehensible without technical background.

Case types we handle

CSAM possession cases — device extraction review, NCMEC report analysis, file sourcing and attribution, AI-generated image identification

Solicitation of a minor — undercover operational review, ICAC standard compliance analysis, communication platform artifacts
Human trafficking with CSAM charges — multi-device analysis, cloud account review, platform subpoena analysis
Opposing examiner review — methodology audit, conclusion verification, preparation for cross-examination
Prosecution support — independent review and pre-trial consultation

Why courts-martial CSAM cases are different

CSAM cases in military courts-martial have procedural and evidentiary features that differ from civilian proceedings. CID and OSI follow different protocols than state or federal agencies. Evidence custody chains move through military channels. The rules of evidence under the Military Rules of Evidence differ from the Federal Rules in specific ways that affect how digital evidence is introduced and challenged.

We have worked CSAM courts-martial from Fayetteville to Okinawa. We know how military evidence handling works, how to navigate the funding approval process through TDS and ADC, and how to testify before a military judge and panel on forensic findings that turn on technical distinctions the panel will need to understand.
