DESCRIPTION

ARTi-C2 is a modern execution framework built to empower security teams to scale attack scenario execution from single and multi-breach point targets with the intent to produce actionable attack intelligence that improves the effectiveness security products and incident response.

PHILOSOPHY

Blackbot Labs believes in creating tools where vendor solutions and open source can be provisioned and managed together by all organizations with the intent to deliver actionable attack intelligence organizations can use to define clear objectives and drive strategic security program initiatives.

Commitment

  • INTEGRITY We develop tools and frameworks that produce accurate attack intelligence to help security teams evaluate the integrity of their security solutions.

  • TRANSPARENCY We work under the umbrella of full transparency during all phases of tool and framework development. From striking up ideas with our community to enhancing the capabilities of tools used by red teams all over the world; if Blackbot Labs is brewing up a new tool or framework, you'll know about it.

  • AGILITY We take pride in enabling lean security teams to remain agile and focused on developing a unique trade-craft that's agnostic to certain tools developed by the red team community. Whether you're keeping tight margins between (MTTD) and (MTTR) metrics or evaluating security controls, we'll be here building tools to help you get the job done faster.

  • SCALABILITY Scaling operational activities is critical to sustaining efficient security ecosystem workflows in modern environments. If our tools don't help you scale your operational capabilities, let us know and we'll fix it.

  • FLEXIBILITY Blackbot Labs builds and delivers open source tools with the flexibility and intent for security professionals to improve their trade-craft and scale security testing initiatives in IT, OT, cloud-native and hybrid workspaces.

  • RAPID DEPLOYMENT Facilitating rapid deployment models is important to us. We'll do our best to deliver practical deployment frameworks that facilitate advanced security eco-systems and data-driven pipelines.

CAPABILITIES

ARTi-C2 Core features and capabilities are sourced from SILENTTRINITY and atomic tests executed through Boo are from ATOMIC-RED-TEAM. All other feature enhancements were built to ensure operational trade-craft, agility, scalability, and rapid execution is not compromised.

CAPABILITY DESCRIPTION
Rapid Deployment Automate and scale testing efforts from single and multi-target breach points located in different regional environments
Modern Command & Control Implant and Server Comms: Uses SILENTRINITY's ECDHE Encrypted C2 Communication capabilities to encrypt C2 traffic over HTTPS. Client and Server Comms: Uses Asyncio, WebSockets, and a prompt-toolkit CLI. Notable features include: - Implant location tagging: Helpful when managing singals and breachpoints in different regions. NGROK integration - Great for staging payloads and deploying them with ngrok URLs
Standard Signature Header JSON PID: , Date(UTC), IsHighIntegrity, HostName, CurrentUser , IsUserAdmin, IPv4, IPv6
JSON Logging Support Streamline, ingest, decode, and analyze evidence with your ELK stack or any Analytics platform ready to parse JSON.
Stageless in Memory Code Execution Execute Atomic Red Team tests from an unmanaged powershell process with low, medium, high integrity.
Dynamic Attack Formations Execute attack-chains without the need to recompile or restart ARTi-C2. Currently supports 3 differnt attack functions. Attack Chains, Attack Profiles, and Attack Scenarios
Modular Payload Delivery ARTi-C2 leverages SILENTRINITY's framework uses unmanaged powershell and stageless powershell stagers to compile and execute Red Team Atomic test payloads in memory, "AS IS"
Operational Management Job IDs are included for controller execution and evidence collection. They're great for event analysis and evidence correlation. "job_id": "D3l820IWpyi67"

MITRE ATT&CK COVERAGE

USE CASES

  • SOCs need to evaluate and improve EDR solutions in minutes
  • Organizations are evaluating different EDR/AV solutions for Windows OS

Organizations need to:

  • execute APT group tactics in controlled environments
  • demonstrate the ability to block common attacks from disk and memory
  • execute lightweight atomoics remotely
  • benchmark critical risk profiles against MITRE ATT&CK before releasing systems to Corp IT/production
  • execute ransomware tactics mapped to ATT&CK safely
  • keep tight margins between (MTTD) and (MTTR) metrics
  • continually improve SOAR workbooks
  • evaluate host security controls between different business units, and regions.

LOGGING CAPABILITIES

By default, ARTIC-C2 logs are written to ARTIC-C2's current working directory in /Atomic-Red-Team-Intelligence-C2/logs/. Session logs include:

  • utc_timestamp : UTC timestamp
  • session: Target session GUID
  • job_id: Unique Job execution ID
  • ttp_data: Technique ID
  • evidence: Base64 encoded evidence collected from breach point target
  • evidence_status: Status to indicate if the TTP executed was blocked or not.
    • 1: TTP was not blocked
    • 0: TTP was partially blocked, or failed to execute

EXECUTION SIGNATURE HEADER

Execution signature headers are used to verify if atomics are blocked by any defenses. In some cases, the actual atomic commands may not return data in STDOUT. However, if the execution signature header returns header information, then this indicates the source code compiled, was loaded into the CLR, and executed on the target breach point. The execution signature header includes:

  • PID: used during technique execution
  • Date: UTC time stamp produced from the breach point target
  • IsHighIntegrity: Process integrity status
  • HostName: breach point target host name
  • CurrentUser: Current user. Great for tracking when users are impersonated
  • IsUserAdmin: Admin status
  • IPv4: IPv4 address info
  • IPv6: IPv6 address info

GENERAL REQUIREMENTS

Listeners

By default, listeners bind to the system's interface with HTTPS:443 and HTTP:80. Listeners must be accessible from tbe assumbed breach point target. Set your Callback URLs in the :> listeners context prior to generating any stager.

BASIC INSTALL

  1. git clone https://github.com/blackbotinc/Atomic-Red-Team-Intelligence-C2.git
  2. cd ./Atomic-Red-Team-Intelligence-C2
  3. ./install.sh install

DEPLOYMENT OPTIONS

ARTIC-C2 enables flexible deployment models to suit all atomic test case execution requirements. While there are a few client-side console dependencies relative caching, the client console is not required to run on the same system as the team server. Soon, we'll package and release a dedicated client.

NOTE: The examples provided below assume ARTIC-C2 will be started from the same instance.

Start WSS on the default port and produce an adhoc log

  • server: artic2.py wss 127.0.0.1 Art1.c25rvr >> /var/log/artic2.log &
  • client: artic2.py client wss://operator:[email protected]:5000

Start WSS on the default port in foreground

  • server: artic2.py wss 127.0.0.1 Art1.c25rvr
  • client: artic2.py client wss://operator:[email protected]:5000

Start WSS on port 5443, bind to 10.0.0.43, produce adhoc log and connect two clients

  • server: artic2.py wss 10.0.0.43:5443 Art1.c25rvr >> /var/log/artic2.log &
  • client1: artic2.py client wss://operator1:[email protected]:5443
  • client2: artic2.py client wss://operator2:[email protected]:5443

DOCUMENTATION:

  • In progress.
