MemScan-EDR scans all running processes, inspects memory for shellcode/injection/C2 patterns, and uses AI (OpenAI / Claude / local models) to classify threats in real time. Built with C# WPF for zero-dependency deployment as a single `.exe`.

## Features
|
|
|
|
### Core Capabilities
|
|
|
|
| Capability | Description |
|
|
|---|---|
|
|
| **Process Enumeration** | Full process list with PID, name, path, parent tree, command line, digital signature, thread count, memory usage |
|
|
| **Memory Scanning** | `VirtualQueryEx` traversal of every committed region; detects RWX private memory, unbacked executable pages |
|
|
| **Signature Matching** | 12 built-in detection rules: NOP sled, CALL/POP EIP, ROR13 hash, CobaltStrike Beacon, Meterpreter, ReflectiveLoader, Mimikatz, etc. |
|
|
| **AI Threat Classification** | Multi-provider support (OpenAI-compatible / Claude / Ollama / LM Studio) + heuristic fallback engine |
|
|
| **CE-MCP Integration** | Auto-launch Cheat Engine MCP server for kernel-level memory operations |
|
|
| **Chinese / English UI** | One-click language toggle; all labels, buttons, and alerts switch instantly |
|
|
| **Single-File EXE** | `dotnet publish` produces a self-contained `MemScan-EDR.exe` — no .NET runtime needed on target |
|
|
|
|
### AI Providers
|
|
|
|
| Provider | Description | Base URL Example |
|
|
|---|---|---|
|
|
| **OpenAI-Compatible** | OpenAI / DeepSeek / Qwen / Zhipu / any OpenAI-format API | `https://api.openai.com/v1` |
|
|
| **Claude** | Anthropic Claude via Messages API | `https://api.anthropic.com` |
|
|
| **Local** | Ollama / LM Studio / vLLM / llama.cpp server | `http://127.0.0.1:11434` |
|
|
| **Heuristic** | Built-in rule engine (no API key needed) | N/A |
|
|
|
|
### Built-in Signatures
|
|
|
|
| Signature | Category | Severity |

|
|
| `SHELLCODE_GETEIP` | Shellcode | Medium |
|
|
| `SHELLCODE_ROR13` | Shellcode | Medium |
|
|
| `C2_COBALTSTRIKE` | C2 | High |

## Architecture
|
|
|
|
```
|
|
TitleBar ── Window Chrome (Min/Max/Close, Language Toggle)
|
|
Sidebar ── Navigation (Dashboard / Processes / Scan / Settings)
|
|
Content ── 4 Views (WPF Grid Visibility switching)
|
|
|
|
Services:
|
|
ProcessCollector ── CreateToolhelp32Snapshot + WMI → ProcessInfo[]
|
|
MemoryScanner ── VirtualQueryEx + signature walk → SignatureMatch[]
|
|
AIAnalyzer ── HTTP → OpenAI/Claude/Ollama API → ScanResult
|
|
CeMcpManager ── Process.Start → python server.py
|
|
```
|
|
|
|
Data flow:
|
|
```
|
|
[Start Scan] → ProcessCollector.CollectAll()
|
|
→ for each ProcessInfo:
|
|
→ MemoryScanner.ScanProcess() → signature matches
|
|
→ MemoryScanner.GetSuspiciousRegions() → RWX private regions
|
|
→ QuickPreScore() — skip API if score < 0.05
|
|
→ AIAnalyzer.AnalyzeProcessAsync() → ScanResult
|
|
→ Update DataGrid / Stats in real-time via IProgress<>
|
|
```
|

## Quick Start
|
|
|
|
### Prerequisites
|
|
|
|
- Windows 10 / 11 (x64)
|
|
- [.NET 8 SDK](https://dotnet.microsoft.com/download/dotnet/8.0)
|
|
- Administrator privileges (for memory scanning)
|
|
|
|
### Build
|
|
|
|
```powershell
|
|
git clone https://github.com/Huang-158/MemScan-EDR.git
|
|
cd MemScan-EDR\src-csharp
|
|
|
|
dotnet build MemScanEDR.sln
|
|
|
|
dotnet publish MemScanEDR\MemScanEDR.csproj -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true -o publish
|
|
|
|
.\publish\MemScan-EDR.exe
|
|
```
|
|
|
|
Or:
|
|
|
|
```powershell
|
|
.\scripts\build_csharp.bat
|
|
```
|
|
|
|
### CE-MCP Setup (Optional)
|
|
|
|
1. Place [ce-mcp-server](https://github.com/Huang-158/ce-mcp-server) next to the project
|
|
2. Or configure the path in Settings → CE-MCP Server Path
|
|
3. Set to `disabled` to run without CE-MCP
|
|
|
|
### AI Configuration
|
|
|
|
1. Select provider: Heuristic / OpenAI-Compatible / Claude / Local
|
|
2. Enter API Base URL
|
|
3. Enter API Key (stored locally)
|
|
4. Enter Model name
|
|
5. Click Save
|
|
|

|
|
## How AI Analysis Works
|
|
|
|
1. **Pre-filter**: Clean processes (signed, system path, no RWX, no sig matches) → `Safe`, skip API
|
|
2. **Structured Prompt**: Each process gets metadata, connections, signatures, suspicious regions
|
|
3. **Safe-by-Default**: AI told >95% are benign; needs multiple concurring indicators
|
|
4. **Heuristic Fallback**: Conservative thresholds (≥0.50 suspicious, ≥0.75 high) when API is down
