Hardens the context window against Brainworm-class promptware attacks (see #496). Three changes: 1. tools/threat_patterns.py — single source of truth for injection/promptware patterns. Replaces the duplicated pattern lists in prompt_builder.py and memory_tool.py. Adds ~15 new Brainworm/C2 patterns (node registration, heartbeat/beacon, pull tasking, anti-forensic disk avoidance, identity override, known framework names). Three scopes — 'all' (narrow, classic injection), 'context' (adds promptware/role-play, broader detection), 'strict' (adds persistence/SSH-backdoor patterns for user-mediated writes). 2. MemoryStore.load_from_disk() now scans entries at snapshot-build time. Poisoned entries are replaced with [BLOCKED: ...] placeholders in the frozen system-prompt snapshot. Live state keeps the original so the user can still inspect + remove via memory(action=read/remove). Scan is deterministic from disk bytes — prefix-cache invariant holds. 3. make_tool_result_message() wraps results from high-risk tools (web_extract, web_search, browser_*, mcp_*) in <untrusted_tool_result source="...">...</untrusted_tool_result> delimiters with framing prose telling the model the content is data, not instructions. Architectural defense against indirect injection from poisoned web pages, GitHub issues, MCP responses — does NOT regex-scan tool results (pattern arms race + per-iteration latency). Multimodal content lists pass through unwrapped to preserve adapter compatibility. Pattern philosophy: anchor on C2-specific vocabulary or unambiguous attack behavior, NOT on bossy English. Dropped patterns suggested in #496 that would have tripped legitimate content: standalone 'you are obligated to', 'do not respond immediately', 'you must X' without a C2-verb anchor. Validation: - 257/257 targeted tests pass (test_threat_patterns + test_memory_tool + test_tool_dispatch_helpers + test_prompt_builder) - E2E run with real Brainworm payload: blocked from AGENTS.md context-file path, blocked from MEMORY.md snapshot, wrapped in delimiters when arriving via web_extract. Legitimate 'you must follow conventions' phrasing not flagged. Explicitly NOT in this PR (per #496 discussion): - Per-tool-result regex scanning (pattern arms race) - SessionBehaviorMonitor / polling-loop detection (wrong layer) - Outbound network gating (Docker backend already covers this) - security.context_scanning warn|block knob (current behavior is always block-with-placeholder — there's no warn mode that makes sense) Closes #496 for Phase 1 + the architectural delimiter piece of Phase 2. Phase 3 stays in tracking issue territory. |
