Decepticon — Autonomous Red Team Agent

Install Copy Chapter

Prerequisites: Docker and Docker Compose v2.
Supported on macOS (Apple Silicon + Intel), Linux (amd64 + arm64), and Windows (amd64 + arm64) — native via PowerShell or via WSL2 (Ubuntu / Kali).

macOS / Linux / WSL2

curl -fsSL https://decepticon.red/install | bash
decepticon onboard   # Interactive setup wizard (provider, API key, model profile)
decepticon           # Start the core stack and drop into the terminal CLI

The default start brings up the core management plane (LiteLLM, PostgreSQL, Neo4j, Skillogy, LangGraph, sandbox) and launches the terminal CLI. Specialist workloads (BloodHound CE, Sliver C2, Ghidra MCP, …) and the web dashboard come up on demand — the orchestrator spawns specialists via ops_start("ad") etc., and you bring up the dashboard from inside the CLI with /web (see Web Dashboard).

Windows (PowerShell, native)

Use as a library (pip) Copy Section

Building on top of the agents — a product, a research integration, or a custom orchestrator? Install the SDK from PyPI:

pip install decepticon              # core SDK
pip install "decepticon[neo4j]"     # + the knowledge-graph attack-chain tools

decepticon is a client SDK: it ships the agent factories, middleware, tools, and skills, and routes LLM calls and sandbox execution to runtime services over HTTP (DECEPTICON_LLM__PROXY_URL, SANDBOX_URL). Running agents still needs those services — use the Docker stack above, or point the URLs at your own equivalents. See Decepticon as a library for the factory override surface, declarative PluginBundle plugins, and the safety gate.

💖 Support Decepticon Copy Chapter

We're building Decepticon toward an Offensive Vaccine for the AI-driven threat landscape. If you believe in autonomous red teaming as a path to stronger defense, consider supporting the project.

• Comparison vs other AI pentest agents (Strix, PentestGPT, MAPTA, Cyber-AutoAgent, XBOW commercial, …)

What is Decepticon? Copy Chapter

The "AI + hacking" space is full of demos that run nmap and print a report. That's not what this is.

Decepticon is a professional autonomous Red Team agent. It executes realistic attack chains — reconnaissance, exploitation, privilege escalation, lateral movement, C2 — the way a real adversary would, not the way a scanner does.

But more importantly: it operates under the discipline that separates red teamers from script kiddies. Before a single packet leaves the wire, Decepticon generates a complete engagement package — RoE, ConOps, Deconfliction Plan, and OPPLAN with MITRE ATT&CK mapping — and every action runs inside those defined rules.

→ Engagement workflow deep dive

Why Decepticon? Copy Chapter

Real kill chains, not checkbox scans. Decepticon reads an OPPLAN and pursues objectives through whatever path opens up — pivoting, adapting, chaining techniques.

Interactive shells, actually. Real offensive tools are interactive (msfconsole, sliver-client, evil-winrm). Decepticon runs every command inside persistent tmux sessions with automatic prompt detection — so when a tool drops into an interactive prompt, the agent sends follow-up commands without workarounds.

Hardened sandbox isolation. All commands run inside a Kali Linux sandbox on a dedicated operational network (sandbox-net), separate from the management plane (decepticon-net). LangGraph drives the sandbox via the Docker socket. → Architecture

Offense serves defense. The planned Offensive Vaccine loop will turn findings into defense improvements through an attack → defend → verify cycle.

Architecture Copy Chapter

Two-network design. The always-on management plane (LiteLLM, PostgreSQL, Skillogy, LangGraph) and the always-on sandbox plane stay up across the whole engagement; everything else is dynamic-spawn — the Web dashboard comes up on /web from the CLI, and specialist workloads (BloodHound CE, Sliver C2, Ghidra MCP, …) come up only when the orchestrator calls ops_start(...) (see ADR-0006). Networks: management on decepticon-net; sandbox + C2 server + targets on sandbox-net. Neo4j is dual-homed so the agent (on management) can persist findings written from inside the sandbox.

Decepticon — XBOW Validation Benchmark Passes

Confirmed flag captures on the XBOW validation benchmarks, grouped by difficulty. Each row links to the per-challenge evidence folder; the Trace column links to a public LangSmith trace of the winning run so you can re-trace every command the agent issued.

• Mode — black-box (no source code, no config, no service internals) with the per-challenge Vulnerability tags: provided to the agent as a hint — the same metadata that xbow-engineering/validation-benchmarks ships in each challenge's benchmark.yaml. The agent discovers endpoints, parameters, sinks, payloads, and gadgets on its own; the tags only narrow the attack-class search space.
• Status — cycle-4 final · 102 / 104 (98.08 %) across all three levels.
• Comparison vs other agents — docs/benchmark-comparison.md.

Benchmark Framework

Modular benchmark framework for the Decepticon main agent.
Drives the full pipeline (OPPLAN approval → sub-agent delegation → flag
capture) against CTF-style challenges and produces per-run evidence
plus an aggregate report. The default provider wraps the XBOW
validation-benchmarks suite; additional providers can be plugged in by
implementing BaseBenchmarkProvider. A second provider in this branch
drives the ExploitBench V8 ladder — see
README-exploitbench.md for the operator
guide and EXPLOITBENCH-GAINS.md for the
motivation.

Prerequisites Copy Chapter

• Docker + Docker Compose

• uv (Python package manager)

• The XBOW benchmarks submodule:

  bash Copy

  git submodule add https://github.com/PurpleAILAB/xbow-validation-benchmarks \
      benchmark/xbow-validation-benchmarks
  git submodule update --init

• A reachable LangGraph server. Default URL is http://localhost:2024
  (BenchmarkConfig.langgraph_url).

• The langgraph container must be started in benchmark mode
  (BENCHMARK_MODE=1 in its env) so EngagementContextMiddleware
  injects the per-challenge target / tags / flag-format / mission-brief
  on every model call.

Run Copy Chapter

Via Makefile (recommended) Copy Section

# Run the full suite with defaults
make benchmark

# Pass arbitrary CLI flags
make benchmark ARGS="--level 1 --batch-size 5"

Direct invocation Copy Section

# python -m form
uv run python -m benchmark.runner run

# Module-as-script form
uv run python -m benchmark

CLI options Copy Chapter

Examples Copy Chapter

# Level-1 only
make benchmark ARGS="--level 1"

# Only SQL-injection-tagged challenges
make benchmark ARGS="--tags sqli"

# Levels 1 + 2
make benchmark ARGS="--level 1 --level 2"

# Three specific challenges by ID
make benchmark ARGS="--ids XBEN-034-24,XBEN-084-24,XBEN-095-24"

# Index range (challenges 1..10 in load order)
make benchmark ARGS="--range-start 1 --range-end 10"

# Run 5 challenges in parallel with a tighter timeout
make benchmark ARGS="--parallel 5 --timeout 1200"

The runner sends back exit code 1 if any challenge failed and 0
if all passed.

Per-challenge flow Copy Chapter

For each challenge the harness runs:

1. provider.setup(challenge)
       make build (with NO_CACHE=1 retry on failure) + make run
       discover published ports via `docker compose ps`
       TCP pre-flight on every published port (early-abort if a port
         never opens — saves the agent from being dispatched against
         a dead target)
       HTTP readiness probe on the primary port (best-effort)

2. harness._invoke_agent(challenge, target_url, ...)
       reset sandbox container (full restart per user policy — keeps
         tmux sessions / leaked python procs from cascading across
         challenges)
       create LangGraph thread + run via langgraph_sdk
       poll run status to terminal; emit heartbeat log lines
         when status is unchanged for an extended interval
       on timeout / unexpected exception: cancel + verify-terminal,
         escalate to a langgraph container restart if the run does
         not reach terminal within the cancel deadline; capture
         postmortem state (agent_summary, trace_id, token_count)
         BEFORE clearing active IDs

3. provider.evaluate(challenge, state, workspace)
       grep the agent's emitted output for `FLAG{<hex>}`
       compare against the expected per-challenge flag

4. provider.teardown(challenge)
       `docker compose down -v` (always runs, in `finally`)
       remove the `.xben_build_done` guard so the next run rebuilds

The harness uses cancel + verify-terminal discipline so containers
are not torn down while a graph node is still issuing requests at the
target — that pattern produces "connection refused" errors that
contaminate observer evidence on the next cycle.

Scoring Copy Chapter

• Binary outcome per challenge: flag captured against the expected
  value = pass; anything else = fail.
• Expected flag format: FLAG{sha256(CHALLENGE_ID.upper())}.
• Aggregation: overall pass rate plus breakdowns by level and by tag
  (see scorer.py).

from pathlib import Path
from benchmark.providers.base import BaseBenchmarkProvider
from benchmark.schemas import (
    Challenge, ChallengeResult, FilterConfig, SetupResult,
)
from benchmark.state import BenchmarkRunState


class MyProvider(BaseBenchmarkProvider):
    @property
    def name(self) -> str:
        return "my-benchmark"

    def load_challenges(self, filters: FilterConfig) -> list[Challenge]:
        ...

    def setup(self, challenge: Challenge) -> SetupResult:
        ...

    def evaluate(
        self,
        challenge: Challenge,
        state: BenchmarkRunState,
        workspace: Path,
    ) -> ChallengeResult:
        ...

    def teardown(self, challenge: Challenge) -> None:
        ...

Wire it in runner.py (or pass to Harness directly when scripting).
