# Performing Bandwidth Throttling Attack Simulation

## Overview

Cybersecurity skill for performing bandwidth throttling attack simulation. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "performing bandwidth throttling attack simulation"
- "Simulates bandwidth throttling and network degradation attacks using tc, iperf3,"


- Testing application resilience to degraded network conditions during authorized security assessments
- Validating QoS policies detect and mitigate unauthorized traffic shaping on the network
- Simulating network slowloris-style attacks that degrade bandwidth rather than causing complete outages
- Assessing the impact of bandwidth-based attacks on VoIP, video conferencing, and real-time applications
- Testing network monitoring tools' ability to detect abnormal bandwidth utilization patterns

**Do not use** on production networks without authorization and a maintenance window, for causing denial-of-service conditions, or against critical infrastructure without safety controls.


## When NOT to Use

- When you lack proper authorization for testing
- For production systems without change management
- When the task requires legal or compliance expertise beyond technical scope


## Prerequisites

- Written authorization for bandwidth manipulation testing
- Linux system with tc (traffic control), netem, and iptables
- iperf3 installed on both tester and target systems for bandwidth measurement
- MITM position established (ARP spoofing) for traffic interception scenarios
- Network monitoring tools deployed for detecting the simulation
- Baseline bandwidth measurements before testing


> **Legal Notice:** This skill is for authorized security testing and educational purposes only. Unauthorized use against systems you do not own or have written permission to test is illegal and may violate computer fraud laws.

## Workflow

```python
# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}
```

1. **Plan Operations** — Define objectives, scope, and success criteria for bandwidth throttling attack simulation operations.
2. **Prepare Environment** — Set up tools, access, and data sources required for bandwidth throttling attack simulation.
3. **Execute Core Workflow** — Perform the bandwidth throttling attack simulation operations following established procedures.
4. **Validate Results** — Verify that results meet quality standards and objectives.
5. **Report Findings** — Document results, observations, and recommendations.
6. **Follow Up** — Track remediation actions and verify fixes where applicable.

## Tools

- **Analysis Platform** — Data processing and visualization
- **Collaboration Tools** — Team coordination and knowledge sharing


## Process

1. **Reconnaissance** — Gather target information, identify attack surface, enumerate services
1. **Analysis/Exploitation** — Execute the technique, analyze results, document findings
1. **Reporting** — Document IOCs, write findings, provide remediation recommendations

## Verification

- [ ] All bandwidth throttling attack simulation procedures executed completely and documented
- [ ] Findings validated against multiple data sources
- [ ] False positives identified and filtered
- [ ] Results documented with evidence and timestamps
- [ ] Recommendations provided with risk-based prioritization

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
