Under the FBI's Universal Case File Number system, 813B-NY-2928278 decodes as classification 813 ("Foreign Intelligence Program" per the NARA-derived FBI classification list), sub-type B, New York Field Office, sequential file 2928278. The 800-series classifications cover the FBI's intelligence programs (800 = Intelligence Program, 801 = Terrorism, 802 = Counterintelligence, 803 = Cyber, 804 = Criminal Intelligence). Classifications 808 through 814 are all labeled "Foreign Intelligence Program" in the publicly reconstructed list, and are believed to correspond to specific countries or regions, with the precise mapping classified.
The single FD-1023 in this file (EFTA01683874) is the only document in the entire EFTA production that shows Epstein as the subject of a foreign-intelligence-program case rather than a criminal one. The handling unit is Squad ID 25 — an intelligence-division squad inside the New York Field Office, distinct from the criminal squads (such as C-20) that worked the trafficking case 50D-NY-3027571. The classification is derived from the FBI National Security Information Classification Guide (NSICG) dated 20120629, with a declassification date of 2042-12-31 (a 25-year timeline standard for national-security material rather than law-enforcement-sensitive material).
Under the FBI's Domestic Investigations and Operations Guide (DIOG), all three levels of investigative activity — assessments, preliminary investigations, and full investigations — generate case file numbers in the Sentinel case-management system. The existence of a case number, a serialized FD-1023, an assigned intelligence squad, and SECRET//NOFORN classification is consistent with any of the three levels; the FD-1023 alone does not disclose which. What it does establish is that the FBI's intelligence division was running Epstein-related material through a foreign-intelligence case file approximately eighteen months before the SDNY criminal investigation (case 50D-NY-3027571) opened in December 2018.
The filing date of 12/13/2017 places the case opening shortly after the 11/27/2017 in-person CHS contact in New York City. The CHS is described in the document as a source with whom the agents had "recently established a relationship" — meaning this FD-1023 is among the earliest reporting from that source, not an established line of intelligence. No subsequent reporting under case number 813B-NY-2928278 appears in the corpus.
The corpus contains exactly one document linked to case 813B-NY-2928278: a 2-page FD-1023 CHS Reporting Document filed under New York Squad ID 25 (EFTA01683874-EFTA01683875). The header records an in-person contact in New York City on 11/27/2017 between two Special Agents and a recently established Confidential Human Source. The classification banner is SECRET//NOFORN, derived from the FBI National Security Information Classification Guide dated 20120629, with declassification on 2042-12-31. The substantive case file number printed on page 1 is 813B-NY-2928278.
The source-reporting narrative on page 2, marked (S//NF), records the CHS's claims about Epstein. The CHS reported that Epstein "had a compound in New Mexico where he lured and video recorded underage women" and "had a private island." The CHS asserted that Epstein "was President Vladimir Putin's wealth manager and provided the same service for Zimbabwean President Robert Mugabe," had "some connection" to a person at the MIT Media Lab, "had dirt on other people," owned "a mansion on the Upper West Side," and "made his money from charging his clients fees to hide their money offshore." The CHS said Epstein "knew former President Bill Clinton, and was very close to current President Donald Trump," adding that "in the spring of 2015, President Trump had just been to Epstein's property for lunch."
The bulk of page 2 is devoted to the CHS's description of an unnamed individual the CHS characterized as "Epstein's personal hacker" — an Italian citizen born in Calabria who developed zero-day exploits and offensive cyber tools and sold them to government customers, including reports that the individual "established the Saudi government's cyber surveillance program," sold a zero-day to Hezbollah, and was the first person to find vulnerabilities in BlackBerry and iOS devices. The narrative states the individual's former company "was acquired by CrowdStrike in fall 2017" and that he was at the time of reporting a Vice President there. It describes a Japanese affiliate company, "three billionaire backers" (Epstein and others) providing seed funding to a separate venture, sales of exploits to GCHQ and a "Central African government," laundering of zero-day proceeds through a California theater company, residence in Dubai and possible Iranian, Israeli, and Vatican City passports, and a refusal to sell tools to "Asian countries." The synopsis line on page 2 reads "Jeffrey Epstein."
What the document does not show: the CHS's identity (Source ID is redacted), the agents' names, the specific predicate or authorization level under which case 813B-NY-2928278 was opened, any subsequent serials in the file, or any indication of how the CHS's claims were evaluated, corroborated, or acted upon. The document is two pages of CHS narrative and standard FD-1023 metadata; it is not an analytical product, an investigative finding, or a charging document. The CHS's claims are unverified raw reporting at the time of filing — including the specific claim that Epstein managed wealth for Putin and Mugabe, which the FD-1023 records but does not assess.
No additional documents linked to this case beyond the must-reads above.
