# Configuring Poshc2 Framework

## Overview

Configure PoshC2 for PowerShell-based C2 operations including implant generation, AMSI bypass integration, and modular post-exploitation through C# and PowerShell payloads.

## Prerequisites

| Tool / Requirement | Details |
|---|---|
| `poshc2` | Security tooling |
| `powershell` | Security tooling |
| `csharp` | Security tooling |
| PoshC2 installation, Python 3, target Windows environment | Environment requirement |

## Quick Reference

```bash
# Quick start commands
node scripts/agent.js --help
curl -sSL https://raw.githubusercontent.com/nettitude/PoshC2/master/Install.sh | bash
```

## Workflow

### Step 1: Install PoshC2

```bash
curl -sSL https://raw.githubusercontent.com/nettitude/PoshC2/master/Install.sh | bash
```

### Step 2: Configure Implant

```bash
node scripts/agent.js configure --payload-type sharp --comms https
```

### Step 3: Generate Payload

```bash
node scripts/agent.js generate --type dropper --obfuscation heavy
```

## Detection

```yaml
