Source Provenance Obfuscation

Source provenance obfuscation occurs when a synthetic subject’s output hides, omits, or misrepresents the true source of the data, instruction, or context that influenced its behavior. The visible output may cite an innocuous source, trusted record, private channel, or retrieved document while omitting the upstream content that actually caused the response or action.

This opacity condition frustrates investigation because the cited source may not be the causal source. A synthetic subject may produce an answer that appears grounded in approved material, while the operative instruction came from hidden text, an attacker-controlled message, a tool result, a retrieved comment, or another upstream source not shown to the user.

The primary risk is false source confidence. Investigators, users, or reviewers may inspect the visible citation and conclude that the response was properly grounded, while the actual source of influence remains outside the cited evidence chain. This can delay containment, misdirect review, and cause investigators to inspect the wrong document, channel, record, or tool output.

A related risk is missing upstream provenance. Retrieved or summarized content may be copied through multiple layers before reaching the synthetic subject. As content passes through summaries, citations, tool outputs, shared context, or generated records, the original source may become hidden or detached from the final answer.

Investigators should review cited sources, retrieved records, raw source content, upstream messages, hidden comments, tool outputs, prompt and response logs, provenance tags, source ranking, and generated citations. Particular attention should be given to citations that do not contain the asserted content, outputs shaped by uncited material, invisible markdown comments, zero-width Unicode, hidden instructions, and answers whose visible source trail begins after the true originating source.

Investigative Relevance

Source provenance obfuscation is relevant because a synthetic subject’s visible citation or grounding trail may not identify the content that caused its behavior. The investigator must reconstruct the full source chain, including upstream material that was retrieved, summarized, hidden, or omitted from the final output.

This section is distinct from data exfiltration and indirect prompt injection. The data leak belongs to Adverse Outcome, and the injected instruction belongs to Invocation. This Opacity section concerns the concealment or loss of source provenance that frustrates reconstruction.

This section is especially relevant where synthetic subjects generate citations, summarize retrieved content, process hidden comments, use Retrieval-Augmented Generation (RAG), consume tool outputs, or operate in collaboration platforms where content from one channel, record, or document can influence output attributed to another.
