offensive-c2-frameworks

offensive-c2-frameworks is a skill for Claude Code, Codex from SnailSploit/Claude-Red. It costs 250 tokens per session (5,611 once invoked), scanned A, original, MIT.

A guide to command-and-control (C2) frameworks, the tools red teams use to communicate with systems during an authorized security exercise. It covers framework selection, setup, communication methods, and supporting infrastructure.

In plain words
What is it for?
Planning network communication, configuring Cobalt Strike or Sliver, setting up redirectors, creating implants, coordinating post-exploitation work, and considering endpoint and network monitoring.
Why use it?
It helps teams choose and configure communications that fit the target environment and reduces the chance that the exercise is exposed too early.

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 A, and why

offensive-c2-frameworks scanned grade A with 1 finding 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 4d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 597 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Offensive C2 Frameworks

Command and Control is the backbone of any sustained red team engagement. Your C2 framework manages implant communication, task distribution, post-exploitation, and lateral movement coordination. Selecting and configuring the right framework -- and layering proper infrastructure around it -- determines whether your operation survives the first 48 hours or burns within minutes of initial access.

This skill covers the major C2 frameworks you encounter in professional red teaming, their configuration for operational security, the infrastructure patterns that protect your backend servers, and the tradecraft decisions that separate detectable operations from resilient ones. You are expected to understand not just how to deploy these tools, but why specific configuration choices matter against modern EDR and network monitoring.

Quick Workflow

  1. Define your engagement's network constraints -- identify allowed egress protocols, proxy requirements, and monitoring posture.
  2. Select a primary C2 framework and transport based on target environment restrictions.
  3. Build redirector infrastructure between your implants and your team server -- never expose the team server directly.
  4. Configure communication profiles to mimic legitimate traffic patterns for the target organization.
  5. Generate implants with appropriate sleep intervals, jitter, and kill dates.
  6. Establish primary and fallback C2 channels using different transports and infrastructure.
  7. Monitor your C2 traffic against detection signatures before deploying to production targets.

Cobalt Strike

Cobalt Strike remains the most widely deployed commercial C2 framework. Its strength lies in malleable C2 profiles, Beacon flexibility, and a mature post-exploitation toolkit. You configure it for stealth through profile customization, sleep management, and BOF execution.

Malleable C2 Profiles

Malleable profiles define how Beacon communicates -- HTTP headers, URI paths, data encoding, and TLS parameters. A well-crafted profile mimics a specific legitimate application.

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.

offensive-c2-frameworks is a skill published in the GitHub repository SnailSploit/Claude-Red (3,023 stars, last pushed 5d ago), licensed MIT. It adds 250 tokens to every session and 5,611 once invoked, about $0.0013 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
