ARTi-C2 is a post-exploitation framework used to execute Atomic Red Team test cases with rapid payload deployment and execution capabilities via .NET's DLR.
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.
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.
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.
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" |

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

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 executionDate
: UTC time stamp produced from the breach point targetIsHighIntegrity
: Process integrity statusHostName
: breach point target host nameCurrentUser
: Current user. Great for tracking when users are impersonatedIsUserAdmin
: Admin statusIPv4

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
artic2.py wss 127.0.0.1 Art1.c25rvr >> /var/log/artic2.log &
artic2.py client wss://operator:[email protected]:5000
Start WSS on the default port in foreground
artic2.py wss 127.0.0.1 Art1.c25rvr
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
artic2.py wss 10.0.0.43:5443 Art1.c25rvr >> /var/log/artic2.log &
artic2.py client wss://operator1:[email protected]:5443
artic2.py client wss://operator2:[email protected]:5443
