Code-review BLOCKER B1. Reaffirms D-011: a `re` stdlib fallback defeats the OPSEC-safe-regex guarantee because hostile C2 output can trigger catastrophic backtracking. The `[:1MB]` slice cap does not mitigate that — re-evaluating a malicious pattern over 1 MB of attacker-controlled text is still a worker freeze. - `mimic.templating.filters` now imports `re2` unconditionally and raises `RuntimeError` at module load if the binding is absent. No `re` import, no `_HAS_RE2` branch, no `_FALLBACK_MAX_INPUT`. - `pyproject.toml` already pinned `google-re2 >= 1.1, < 2.0`; this commit hardens the import path to actually enforce it. - New test `test_re2_is_required` asserts the binding is wired in.
Mimic
Internal BAS (Breach & Attack Simulation) platform for the Red Team. Replays TTPs from engagement journals or an internal ATT&CK library against client infrastructure through VPN/relay, in white-glove coordination with the SOC.
Output: a coverage report mapped to MITRE ATT&CK — measurable, reproducible, archived.
Status
ready-with-prereqs — spec frozen on 2026-05-19, 23 review patches integrated.
Code start blocked on:
- PR1 — Mythic API documentation + pinned version (lead RT)
- PR2 — Internal C2 interface spec + journal export example (internal C2 team)
- PR3 — RT graphic charter for the PDF report (lead RT)
While PR1/PR2/PR3 are open, sprint 0 focuses on the unblocked skeleton.
Spec
The authoritative spec lives in the RT-SecondBrain vault:
Projects/Mimic — Spec.md. Do not duplicate it here.
In-repo documentation:
CHANGELOG.md— chronological log of features, decisions, rollbacks.tasks/spec-decisions.md— implementation arbitrations on top of the spec.tasks/todo.md— current sprint backlog.
Stack (frozen)
- Backend Python 3.12 / Flask / Flask-SocketIO / SQLAlchemy 2 / Pydantic 2 / Alembic / WeasyPrint / pytest + testcontainers / ruff / mypy strict
- Frontend TypeScript / React 18+ / Vite / Tailwind 4 / TanStack Query 5 / Recharts / Playwright
- Storage Postgres (prod) / SQLite (pure-logic unit tests) / testcontainers Postgres (audit log, RBAC, write-only role — incl. unit tests of Postgres-specific behavior, per H38)
- Deploy Docker images + Ansible deployment playbook (per D-010). Reverse proxy (Caddy + TLS + IP allowlist) handled by existing RT infrastructure, out of Mimic scope (D-007).
