- Flask app factory wires SQLAlchemy / Migrate / Login / SocketIO and
registers every blueprint. /healthz smoke endpoint included.
- Pydantic 2 DTOs (request/response) for engagement / host / TTP /
scenario aggregates with from_attributes=True conversion.
- Flat CRUD blueprints under /api/v1/:
* engagements (list / create / get / put / delete-as-archive)
* hosts (engagement-scoped CRUD)
* library/ttps (CRUD; promote requires the lead-only TTP_PROMOTE)
* scenarios + steps (F3 invariant enforced: host.c2_type must match
scenario.c2_type at compose time, 400 otherwise).
- @require_perm guards every endpoint per the F11 matrix.
- audit/ writer is hash-chained from v1 (SHA-256 of canonical record
plus previous hash). The SQL-level write-only role enforcement ships
in the deploy playbook (idempotent grants run at migration time).
- mimic-cli (click): user create (seeds RT operator/lead with group
membership), db dump / db restore (manual pg_dump/pg_restore, R-O1).
No orchestrator, no WebSocket, no report generation — those land after
PR1/PR2/PR3.
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.
