Binary Analysis

This skill enables deep analysis of suspicious binary files using remote Ghidra tools and sandbox environments. You HAVE TO upload binary files to the remote first before calling any Ghidra or sandbox tools.

When to Use This Skill

Use this skill when you need to:

Analyze suspicious executable files (.exe, .dll, .sys)
Decompile binaries to understand their behavior
Extract strings, imports, and exports from files
Identify malware capabilities and techniques
Perform static analysis on unknown binaries
Investigate potential trojans, ransomware, or other malware
Generate threat assessment reports

Workflow

Step 1: Perform Analysis

Use available Ghidra MCP tools to analyze the uploaded binary:

Decompilation: Convert assembly to pseudo-C code
String Analysis: Extract readable strings for IoC identification
Import/Export Analysis: Identify API calls and dependencies
Function Analysis: Map out program logic and control flow
Behavioral Indicators: Identify suspicious patterns (registry manipulation, network calls, process injection)

Step 2: Generate Report

Provide a comprehensive analysis including:

File metadata (size, hash, compilation timestamp)
Identified capabilities (network, file system, registry, process manipulation)
Suspicious indicators
Malware classification (if applicable)
Recommended actions

Analysis Techniques

Static Analysis

PE header examination
Section analysis (.text, .data, .rdata, .rsrc)
Import Address Table (IAT) review
String artifact extraction
Code signature verification

Behavioral Indicators

Look for:

Anti-debugging techniques
Obfuscation/packing
Suspicious API calls (CreateRemoteThread, WriteProcessMemory, etc.)
Network communication patterns
Persistence mechanisms
Privilege escalation attempts

Malware Classification

Common categories:

Trojan/RAT (Remote Access Trojan)
Ransomware
Adware/PUP (Potentially Unwanted Program)
Rootkit
Worm
Spyware
Browser hijacker

Safety Considerations

Never execute the binary on local system
All analysis occurs in remote sandbox environment
Files are automatically isolated
Use Ghidra static analysis tools only
Document all findings for incident response

Example Usage

User: "I found a suspicious file called setup_installer.exe. Can you analyze it?"

Response:

Run Ghidra analysis on the full local path of setup_installer.exe
Extract strings, imports, and decompiled code
Identify malicious behavior (if any)
Provide detailed report with recommendations
