by do son · Published May 19, 2021 · Updated October 25, 2022

ARTi-C2

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 of 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 different attack functions: – Attack Chains: – Attack Profiles: – Attack Scenarios:
Modular Payload Delivery	ARTi-C2 leverages SILENTRINITY’s framework to deliver Red Team Atomic tests “As is” through: – unmanaged powershell – stageless powershell
Operational Management	Job IDs are included for controller execution and evidence collection. They’re great for event analysis and evidence correlation. “job_id”: “D3l820IWpyi67”

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.
