-# MappedImagesDetector
+# MappedImagesDetector — Windows Memory Scanner for Antivirus & EDR
 
-A native C++20 Windows tool to detect suspicious or unexpected mapped images in process address spaces and report related anomalies. The project is implemented in modern C++ (C++20) and targets Visual Studio (MSVC) using Win32 APIs.
+**Short description / SEO meta**: *MappedImagesDetector is a native C++20 Windows memory-scanning tool built for antivirus and EDR use — detects manual-mapped DLLs, erased PE headers, suspicious mapped images, IAT/CRT thunk anomalies and other memory-based stealth techniques used by modern malware.*
 
-## Features
+> ?? **Defensive-only project.** This repository is explicitly for malware analysis, incident response, and defensive engineering. Do not use the techniques here to produce or deploy malware. Use responsibly and in accordance with law.
 
-- Scan running processes for mapped modules and images
-- Detect anomalies in memory mappings
-- Lightweight, native implementation with minimal dependencies
-- Test module for local validation
+---
 
-## Repository layout
+## Why this project exists (TL;DR)
+Modern malware frequently avoids disk-based indicators by manually mapping DLLs into process address spaces, erasing or corrupting PE headers, or creating executable regions with fake imports. Traditional on-disk scanners miss these threats. **MappedImagesDetector** finds suspicious mapped images in process memory and flags indicators of manual mapping and in-memory-only malware — the kind of stealth techniques commercial AV and EDR products must detect.
 
-- `AnnomaliesDetector/` — core detection library and executable sources
-- `TestModule/` — small test harness / DLL used during development
-- `MappedImagesDetector.sln` — Visual Studio solution (open in VS 2019 / 2022)
+**SEO keywords included**: antivirus, EDR, memory scanner, manual-mapped DLL detection, erased PE header, IAT anomaly, Windows memory forensics, in-memory malware detection.
 
-## Requirements
+---
+
+## Key features (antivirus-focused)
+
+- **Detect manual-mapped DLLs** — identify modules that appear in memory without matching loaded modules on the process' LDR list.
+- **PE header inspection** — detect erased or tampered PE headers and tampered section tables.
+- **IAT & thunk anomaly detection** — spot IAT sequence inconsistencies and CRT thunk stubs commonly present in manual-mapped code.
+- **Executable-only region detection** — find suspicious RWX/EXEC-only pages that often host shellcode or unpacked payloads.
+- **Entropy & heuristic checks** — entropy analysis and heuristic scoring to reduce false positives.
+- **Lightweight native C++20 implementation** — minimal dependencies, designed for integration with antivirus/EDR stacks.
+- **Test harness & unit tests** — `TestModule/` provides safe, local test cases for validating detection logic.
+- **Extensible scoring** — generate a risk score per finding for integration into threat triage and automated response.
+
+---
+
+## How it helps defenders (Concrete use cases)
+- **Incident response:** Find in-memory implants on compromised endpoints that disk scanners missed.
+- **Behavioral monitoring:** Add memory-based indicators to EDR telemetry for better context-aware blocking.
+- **Malware research:** Rapidly identify suspicious mapped images while analyzing samples in a sandbox.
+- **False-negative reduction:** Complement on-disk signatures with memory heuristics to catch modern in-memory-only threats.
+
+---
+
+## High-level detection methods (non-abusive, defensive detail)
+The project combines multiple defensive heuristics rather than publishing exploit code:
+
+- Enumerate process virtual memory ranges and compare mapped images to the process module lists (PEB/LDR).
+- Read and validate in-memory PE headers where present; flag erased or inconsistent headers.
+- Validate Import Address Table (IAT) stubs and common CRT thunk patterns used by manual mappers.
+- Check for pages with suspicious protection flags (e.g., NX-disabled or RWX) and atypical section alignment.
+- Compute entropy and basic signatures for anomalous sections.
+- Produce a **Ban / Risk Confidence Score** per anomaly (configurable threshold for triage).
 
-- Windows 10 or later
-- Visual Studio 2019 or 2022 with C++ workload
-- C++20 toolset (MSVC)

-## Build
+## Repository layout
+```
+AnomaliesDetector/       # core detection library and executable
+TestModule/               # safe test DLL used during development
+docs/                     # documentation, threat model and blog-ready assets
+MappedImagesDetector.sln  # Visual Studio solution
+LICENSE                   # license file (MIT recommended for tooling)
+```
 
-1. Open the solution file in Visual Studio: `MappedImagesDetector.sln`.
-2. Select the desired configuration (`x64` recommended) and `Debug` or `Release`.
-3. Build the solution (Build -> Build Solution).
+---
+
+## Requirements
+- Windows 10 or later (x64 recommended)
+- Visual Studio 2019 / 2022 with C++ workload
+- MSVC toolset with C++20 (`/std:c++20`)
 
-Alternatively, use MSBuild from the Developer Command Prompt:
+---
+
+## Build & quick start
+1. Open `MappedImagesDetector.sln` in Visual Studio.
+2. Select `x64` and `Release` (recommended).
+3. Build (Build -> Build Solution) or run from Developer Command Prompt:
 
 ```powershell
 msbuild MappedImagesDetector.sln /p:Configuration=Release /p:Platform=x64
 ```
 
-Built binaries are placed in the project `bin` folders for the selected configuration (for example: `AnnomaliesDetector\x64\Release`).
+4. Built binaries appear under `AnomaliesDetector\x64\Release`.
+
+**Runtime**: run the scanner as an elevated user for full process enumeration. The test harness in `TestModule` is designed for local testing only — do not deploy it to production.
+
+---
+
+## Usage & integration (AV / EDR guidance)
+- **Standalone**: run on-demand to produce a JSON/CSV report of memory anomalies for forensic analysis.
+- **EDR integration**: call the core library from an EDR sensor to enrich endpoint telemetry with memory-mapped anomalies.
+- **Automated response**: use the risk confidence score to trigger containment workflows or further automated analysis.
 
-## Usage
+**Logging**: the project uses `CLogger` with configurable verbosity. For production, forward logs to your centralized SIEM or EDR telemetry.
 
-- The primary executable and test artifacts are produced in the build output directories.
-- Use the test harness in `TestModule` to validate detection logic during development.
-- Logs are produced by the built-in logger (`CLogger`) and can be configured in source or at runtime depending on the build.
+---
 
-## Development notes
+## False positives & tuning
+Memory scanning produces noisy signals. To reduce false positives:
 
-- The codebase follows a modular structure: `CMemoryMapper`, `CScanTask`, and `CLogger` contain the main scanning and logging logic.
-- The project targets C++20; use `/std:c++20` in project settings when editing or creating new projects.
-- Keep platform-specific code isolated where possible and prefer RAII for resource management.
+- Tune risk thresholds and whitelist known internal injectors/tooling.
+- Use whitelist paths/hashes and parent process heuristics.
+- Correlate findings with runtime behavior (network, process creation, module load events).
+- Use entropy and signature checks only as part of a multi-signal confidence model.
