# Performing Integer Overflow Attacks

## Overview

Exploit integer overflow and underflow conditions to corrupt memory allocations, bypass size checks, and achieve code execution in native applications.

## Prerequisites

| Tool / Requirement | Details |
|---|---|
| `gdb` | Security tooling |
| `pwntools` | Security tooling |
| `afl` | Security tooling |
| GDB, pwntools, understanding of integer promotion rules in C | Environment requirement |

## Quick Reference

```bash
# Quick start commands
node scripts/agent.js --help
objdump -d ./target | grep -E 'add|mul|imul|sub'
```

## Workflow

### Step 1: Identify Integer Operations

```bash
objdump -d ./target | grep -E 'add|mul|imul|sub'
```

### Step 2: Fuzz Integer Boundaries

```bash
node scripts/agent.js fuzz --binary ./target --input-type int
```

### Step 3: Craft Overflow Payload

```bash
node scripts/agent.js exploit --binary ./target --value 0xFFFFFFFF
```

## Detection

```yaml

**Detection Opportunities**

| Indicator | Source | Detection Logic |
|---|---|---|
| Integer Overflow Attacks Detection | windows/process_creation | Sigma rule (critical) |
| ATT&CK Coverage | MITRE ATT&CK | T1203 |

## Verification

- **Verify overflow condition**: `node scripts/agent.js analyze --binary ./target`
- **Confirm exploitation**: `node scripts/agent.js exploit --binary ./target --value 0xFFFFFFFF`
