# Analyzing Heap Spray Exploitation


## Genel Bakış

Heap spraying is an exploitation technique that fills large regions of a process's heap with attacker-controlled data (typically NOP sleds followed by shellcode) to increase the reliability of code execution exploits. bu skill covers Tespit etme heap spray artifacts in memory dumps using Volatility3's malBul:, vadinfo, and memmap plugins, identifying suspicious contiguous memory allocations, scanning for NOP sled patterns (0x90, 0x0c0c0c0c), and extracting embedded shellcode for analysis.


## Ne Zaman Kullanılır

- investigating yaparken security incidents that require analyzing heap spray exploitation
- building yaparken Tespit rules or threat hunting queries for this domain
- SOC yaparken: analysts need structured procedures for this analysis type
- validating yaparken security monitoring coverage for related attack techniques

## Ön Gereksinimler

- Python 3.9+ with `volatility3` framework installed
- Memory dump file (.raw, .vmem, .dmp format)
- Understanding of virtual memory layout and VAD (Virtual Address Descriptor) trees
- Familiarity with common shellcode patterns and NOP sled encodings

## Adımlar

### Adım 1: Identify Suspicious Processes
Use Volatility3 windows.malBul: to scan for processes with executable injected memory regions.

### Adım 2: Analyze VAD Entries
İncele: VAD tree entries using windows.vadinfo for large contiguous allocations with RWX permissions.

### Adım 3: Scan for NOP Sled Patterns
Search suspicious memory regions for NOP sled signatures (0x90 sequences, 0x0c0c0c0c patterns).

### Adım 4: Extract and Analyze Shellcode
Dump suspicious memory regions and identify shellcode using byte pattern analysis.

## Expected Output

JSON report with suspicious processes, heap spray indicators, NOP sled locations, memory region sizes, and extracted shellcode hashes.
