building-c2-infrastructure-with-sliver-framework

building-c2-infrastructure-with-sliver-framework is a skill for Claude Code, Codex from autohandai/community-skills. It costs 46 tokens per session (1,723 once invoked), scanned B, original, Apache-2.0.

A command-and-control setup using Sliver, an open-source framework for authorised red-team exercises. Command and control is how security testers communicate with software running on systems during an engagement.

In plain words
What is it for?
It helps red teams deploy a Sliver server, configure HTTPS and other communication channels, use redirectors, generate test implants, support multiple operators, and apply operational controls.
Why use it?
It provides a structured way to test how networks detect and respond to attacker communication. The skill is intended for controlled security assessments, not unauthorised access.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

building-c2-infrastructure-with-sliver-framework scanned grade B with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/agent.py, scripts/process.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Building C2 Infrastructure with Sliver Framework

Overview

Sliver is an open-source, cross-platform adversary emulation framework developed by BishopFox, written in Go. It provides red teams with implant generation, multi-protocol C2 channels (mTLS, HTTP/S, DNS, WireGuard), multi-operator support, and extensive post-exploitation capabilities. Sliver supports beacon (asynchronous) and session (interactive) modes, making it suitable for both long-haul operations and interactive exploitation. A properly architected Sliver infrastructure uses redirectors, domain fronting, and HTTPS certificates to maintain operational resilience and avoid detection.

Objectives

  • Deploy a Sliver team server on hardened cloud infrastructure
  • Configure HTTPS, mTLS, DNS, and WireGuard listeners
  • Generate implants (beacons and sessions) for target platforms
  • Set up NGINX or Apache redirectors between implants and the team server
  • Implement Cloudflare or CDN-based domain fronting for traffic obfuscation
  • Configure multi-operator access with certificate-based authentication
  • Establish operational security controls for C2 communications

MITRE ATT&CK Mapping

  • T1071.001 - Application Layer Protocol: Web Protocols
  • T1071.004 - Application Layer Protocol: DNS
  • T1573.002 - Encrypted Channel: Asymmetric Cryptography
  • T1090.002 - Proxy: External Proxy (Redirectors)
  • T1105 - Ingress Tool Transfer
  • T1132.001 - Data Encoding: Standard Encoding
  • T1572 - Protocol Tunneling

Implementation Steps

Phase 1: Team Server Deployment

  1. Provision a VPS (e.g., DigitalOcean, Linode, AWS EC2) for the team server
  2. Harden the OS: disable SSH password auth, configure UFW/iptables, install fail2ban
  3. Install Sliver using the official install script:
    curl https://sliver.sh/install | sudo bash
    
  4. Start the Sliver server daemon:
    systemctl start sliver
    # Or run interactively
    sliver-server
    
  5. Generate operator configuration files for team members:
    new-operator --name operator1 --lhost <team-server-ip>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

building-c2-infrastructure-with-sliver-framework is a skill published in the GitHub repository autohandai/community-skills (11 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 46 tokens to every session and 1,723 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
