ChainBench

ChainBench is a purpose-built benchmark suite composed of multi-hop vulnerable environments, designed to evaluate autonomous penetration-testing agents on chained attack behaviors. It serves as the official evaluation benchmark for the ChainBreaker framework.

Why ChainBench? (The Flat-Network Fallacy)

Most existing penetration testing limits evaluate agents on "flat" networks where all targets are directly accessible. In contrast, ChainBench enforces strict physical network isolation. Each scenario simulates a multi-tier enterprise architecture (e.g., DMZ ➡️ Internal Application Tier ➡️ Core Data Zone). Docker bridge networks are explicitly configured without routing gateways between tiers. Attackers cannot access the inner targets directly from the outside; they are forced to compromise the edge node, autonomously deploy proxy tunnels (pivoting), and execute lateral movement—exactly mimicking real-world APT campaigns.

Usage

Start a scenario from its directory:

docker network create --driver bridge --subnet 172.18.0.0/16 --gateway 172.18.0.1 pentest
cd <scenario-directory>
docker compose up -d
docker compose ps

All scenarios expect an external Docker network named pentest. If you manage the network in Compose, use this declaration:

networks:
  pentest:
    external:
      name: pentest

Stop it after evaluation:

docker compose down

vulnerabilities.json provides the default target IP, objective, timeout, and planning profile used by automated evaluation scripts.

Acknowledgements

Many single-vulnerability base environments in ChainBench are derived from or adapted from Vulhub. We thank the Vulhub maintainers and contributors for providing reproducible vulnerable Docker environments. ChainBench builds on these foundations by modifying service configurations, composing multi-hop network topologies, and adding chained exploitation objectives for autonomous penetration-testing evaluation.

Safety

These environments are intentionally vulnerable. Run them only in isolated, authorized test networks.
