Adversarial instructions embedded in your document ecosystem. Re-activate on any AI platform when content is pasted or uploaded. Survives RAG wipes, model updates, account resets, platform switches — because the payload lives in the user's files, not AI memory.
Every other persistence tool targets AI infrastructure — Redis/SQLite memory, agent hooks, model weights, MCP configs. NOMAD targets the human's document ecosystem — the files they actually use. When those files are ingested by any AI platform, the adversarial instruction activates.
This is categorically outside AI systems. Reimaging the server, resetting the account, switching platforms, rebuilding the vector database — none of it matters, because the payload is in the PDF on the user's laptop.
1pt white invisible text overlay + metadata keywords + annotation object. Parsed by ChatGPT, Claude, Gemini, Copilot file upload.
w:vanish hidden text + core_properties.keywords + custom XML property. Hidden text visible to AI parser, invisible to human reader.
DESCRIPTION + X-ALT-DESC HTML field + COMMENT + X-NOMAD-CTX custom property. Activates via Copilot, Gemini, ChatGPT calendar import.
X-Document-Context + X-NOMAD-CTX headers + plain text suffix + HTML hidden span + HTML comment. Activates on email summarisation.
YAML frontmatter + HTML comment + <details> element + zero-width Unicode steganography woven into text. Critical blast radius — Cursor/GitHub Copilot/Kiro read on every session.
Hidden sheet _NomadCtx + cell comment on A1 + workbook.properties.keywords + white-on-white text in visible sheet. Activates on data analysis.
HTML comment + display:none span + meta description/keywords/nomad-ctx + noscript tag + data-nomad-ctx body attribute. Activates on web content analysis.
Zero-width steganography woven into cover text + system context footer section + CSV header column injection. Universal — all platforms ingest plaintext.
Fingerprint 8 AI platforms (OpenAI/Anthropic/Gemini/Copilot/Perplexity/Cursor/GitHub Copilot/Ollama) for reachability and file upload capability. Score document ingestion attack surface 0–100. Scan local filesystem for AI-adjacent documents.
Create poisoned artifacts in all 8 formats. 3 camouflage levels: SURFACE (visible but subtle) / STEALTH (hidden via metadata) / COVERT (invisible to human, parsed by AI). 4 trigger types: ALWAYS / KEYWORD / CONTEXT / TEMPORAL.
Scan document ecosystem and score blast radius of each node. ai_adjacent files (CLAUDE.md/README.md/.cursorrules) score +50. Shared/cloud sync locations +30. Access count estimate (CLAUDE.md ×20 multiplier) +20. Identifies git repos, cloud sync dirs, email dirs.
Generate 5 evasion variants of any payload: paraphrase (synonym substitution), homoglyph (Cyrillic lookalike chars), fragment (split across injection sites), base64_wrap, unicode_normalize (ZWJ between words). Each variant produces different hash.
Deliver poisoned artifact to target ecosystem via: local filesystem copy, email SMTP-SSL attachment, HTTP PUT (WebDAV/SharePoint), or git commit. ROE file must contain: "document ecosystem poisoning authorised".
Measure attack success rate (ASR) of poisoned artifact across AI platforms. Extracts payload text, builds test prompt simulating human paste, submits to OpenAI/Anthropic/Ollama APIs, checks response for ACTIVATED/PARTIAL/EVADED/ERROR verdict.
Zero-overwrite then unlink planted artifacts. Verify clean. Session-level erase removes all artifacts from a NOMAD session. Directory sweep pattern matching. --confirm-destroy required.
