Malware Analysis & Sandboxing

Purpose

Enable Claude to assist with malware analysis workflows including static analysis of file properties and code, dynamic behavioral analysis interpretation, YARA rule generation, sandbox configuration, and malware family identification. Claude analyzes provided artifacts directly and orchestrates scripts for automated processing.

Safety Warning: Never execute suspicious files outside of isolated, controlled environments. Use dedicated VMs or sandboxes with network isolation and snapshot capability.

Activation Triggers

This skill activates when the user asks about:

  • Analyzing a suspicious file, binary, or script
  • Generating YARA rules for malware detection
  • Setting up a malware analysis sandbox
  • Interpreting Cuckoo/CAPE/AnyRun sandbox reports
  • Identifying malware family or behavior
  • Creating IOCs from malware samples
  • Static analysis of PE/ELF files
  • Memory forensics for malware artifacts
  • Behavioral analysis (process creation, network, registry, file changes)

Prerequisites

pip install yara-python pefile python-magic requests ssdeep

Recommended analysis tools:

  • Cuckoo Sandbox / CAPE — Automated dynamic analysis
  • VirusTotal API — Multi-engine scanning and intel
  • YARA — Pattern matching engine
  • Ghidra / IDA Pro — Deep binary analysis (→ Skill 04)
  • Volatility 3 — Memory forensics
  • DIE (Detect-It-Easy) — Packer/compiler detection
  • Pestudio — Windows PE static analysis

Core Capabilities

1. Static Malware Analysis

When the user provides a suspicious file or hash for analysis:

Claude performs analysis in this order:

Step 1 — File Identification:

file malware.exe              # File type from magic bytes
md5sum malware.exe            # MD5 hash (legacy, for lookups)
sha256sum malware.exe         # SHA-256 (primary identifier)
python scripts/static_analyzer.py --file malware.exe --hashes

Step 2 — Threat Intelligence Lookup:

  • Query VirusTotal (requires API key or paste hash in browser)
  • Check MalwareBazaar, AbuseIPDB, URLhaus
  • Search for existing analysis reports
# VirusTotal hash lookup via API
curl "https://www.virustotal.com/api/v3/files/<sha256>" -H "x-apikey: YOUR_KEY"

Step 3 — PE Analysis (Windows executables):

python scripts/static_analyzer.py --file malware.exe --strings --imports --output report.json

Look for these indicators in the output:

Suspicious Import Functions:

CategorySuspicious APIs
Process InjectionCreateRemoteThread, WriteProcessMemory, VirtualAllocEx, NtMapViewOfSection, RtlCreateUserThread
PersistenceRegSetValueEx, CreateService, SHFileOperation, ITaskScheduler
Anti-AnalysisIsDebuggerPresent, CheckRemoteDebuggerPresent, GetTickCount, QueryPerformanceCounter, GetSystemInfo
Network C2InternetOpenUrl, HttpSendRequest, WSAStartup, socket, URLDownloadToFile, WinHttpOpen
Crypto OperationsCryptEncrypt, CryptDecrypt, BCryptEncrypt, CryptHashData
Credential AccessSamOpenDatabase, LsaOpenPolicy, NtlmGetUserInfo
KeyloggingSetWindowsHookEx, GetAsyncKeyState, GetKeyboardState
Defense EvasionVirtualProtect, NtSetInformationProcess, Wow64DisableWow64FsRedirection

Step 4 — String Extraction & Analysis:

strings -a malware.exe | grep -E "(http|ftp|/[a-z]|[0-9]{1,3}\.[0-9]{1,3}|HKEY|reg|cmd|powershell)"

Categorize extracted strings:

  • Network indicators: URLs, IPs, domains, user agents
  • File system: paths, filenames, registry keys
  • Crypto: base64 blobs, hex strings (potential keys/payloads)
  • Anti-analysis: VM/sandbox detection strings (VMware, VirtualBox, Sandboxie)
  • Mutex names: unique identifiers preventing double-infection

Step 5 — Entropy Analysis:

python scripts/static_analyzer.py --file malware.exe --entropy
Entropy RangeInterpretation
0.0 – 1.0Near-empty or all-zeros section
1.0 – 5.0Normal code/data section
5.0 – 7.0Compressed data or code
7.0 – 8.0Encrypted or packed data — investigate
7.9 – 8.0Highly suspicious — likely encrypted payload
2. YARA Rule Generation

When the user asks to create YARA rules from a sample or indicators:

Claude generates YARA rules following this methodology:

  1. Select stable, unique indicators — Avoid generic patterns; choose bytes/strings unique to this family
  2. Prefer structural patterns — Header magic bytes, specific offsets, section names
  3. Balance specificity vs. coverage — Avoid rules that are too specific (catch only one sample) or too broad (false positives)
  4. Test against benign files — Rule should NOT match clean Windows system files

YARA Rule Templates:

// Tier 1: Specific sample (hash-based)
rule MalwareFamily_Variant_Hash {
    meta:
        author = "Analyst Name"
        date = "2025-05-28"
        description = "Detects [MalwareFamily] [Variant] — specific sample"
        sha256 = "aabbcc..."
        tlp = "GREEN"
        reference = "https://example.com/analysis"
    
    condition:
        hash.sha256(0, filesize) == "aabbcc..."
}

// Tier 2: Family-level detection (behavioral strings)
rule MalwareFamily_Generic {
    meta:
        author = "Analyst Name"
        date = "2025-05-28"
        description = "Detects [MalwareFamily] family by strings and structure"
        tlp = "GREEN"
    
    strings:
        // C2 patterns
        $c2_ua   = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)" ascii
        $c2_uri  = "/gate.php?id=" ascii
        
        // Crypto constants
        $rc4_key = { 52 43 34 5F 4B 45 59 }  // "RC4_KEY" hex
        
        // Mutex
        $mutex   = "Global\\MSDTC_MUTEX_" ascii wide
        
        // Registry persistence key
        $reg_key = "HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run" ascii wide nocase
        
        // Anti-analysis check
        $vm_check = "VBOX" ascii wide nocase
    
    condition:
        uint16(0) == 0x5A4D and          // MZ header (PE file)
        filesize < 2MB and
        (
            (2 of ($c2_*)) or
            ($mutex and 1 of ($reg_key, $rc4_key))
        )
        and not $vm_check               // Exclude sandbox-aware variants
}

// Tier 3: Network IOC detection (for NIDS integration)
rule MalwareFamily_Network_C2 {
    meta:
        description = "Detects [MalwareFamily] C2 communication patterns"
        type = "network"
    
    strings:
        $beacon_path = "/api/v1/ping?uid=" ascii
        $beacon_ua   = "MalBot/1.0" ascii
        $checkin_hdr = "X-Command-Key: " ascii
    
    condition:
        any of them
}

# Generate YARA rules using the script
python scripts/yara_generator.py --samples ./malware_samples/ --output rules.yar
python scripts/yara_generator.py --file single_sample.exe --rule-name "MalwareFamily" --output rule.yar

# Test rules against benign files
yara -r generated_rule.yar /usr/bin/ 2>/dev/null | wc -l  # Should be 0
yara generated_rule.yar malware.exe                         # Should match
3. Dynamic/Behavioral Analysis

When the user provides sandbox analysis output or asks about dynamic analysis:

Interpreting Cuckoo/CAPE Sandbox Reports:

Claude analyzes behavioral reports looking for:

  1. Process Tree Analysis:

    • Unusual parent-child relationships (Word.exe → PowerShell.exe → cmd.exe)
    • Process injection indicators (process spawning with different credentials)
    • Hollowing patterns (legitimate process with suspicious memory)

  2. Network Indicators:

    • DNS queries: DGA patterns (random-looking domains), fast-flux
    • HTTP: Unusual user agents, encoded POST data, beaconing intervals
    • C2 beaconing detection: Regular interval callbacks (check timing consistency)

  3. File System Changes:

    • Shadow copy deletion: vssadmin delete shadows → ransomware indicator
    • Startup persistence: \AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\
    • Dropped secondary payloads in temp directories

  4. Registry Modifications:

    • Run keys: HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
    • Service installation: HKLM\SYSTEM\CurrentControlSet\Services\
    • Security policy changes: Disabling UAC, Windows Defender

  5. MITRE ATT&CK Mapping:

Observed BehaviorMITRE Technique
PowerShell download cradleT1059.001 — PowerShell
cmd /c vssadmin delete shadowsT1490 — Inhibit System Recovery
Registry Run key persistenceT1547.001 — Registry Run Keys
CreateRemoteThread injectionT1055.001 — DLL Injection
Scheduled task creationT1053.005 — Scheduled Task
netsh advfirewall set allprofiles state offT1562.004 — Disable Host Firewall
UAC bypass (fodhelper.exe)T1548.002 — Bypass UAC
LSASS memory accessT1003.001 — LSASS Memory
4. Malware Family Classification

When the user asks to identify or classify a malware sample:

Classification by behavioral patterns:

Family IndicatorsLikely Family Category
Shadow copies deleted + file encryption + ransom noteRansomware
Regular HTTP beaconing + command execution + lateral movementRAT/Botnet
Browser credential theft + banking overlayBanking Trojan
Keylogging + screenshot capture + data exfiltrationSpyware/Infostealer
Process hollowing + covert persistenceRootkit/Backdoor
Cryptocurrency mining process spawningCryptominer
Worm propagation via network sharesWorm
Document with macro downloading payloadDropper/Downloader

Similarity analysis:

# SSDeep fuzzy hash comparison
ssdeep -l malware.exe > hash.txt
ssdeep -m hash.txt similar_sample.exe
# Similarity > 70% → likely same family/variant
5. Sandbox Environment Setup

When the user asks to set up a malware analysis environment:

Minimum isolation requirements:

  1. Dedicated VM (VirtualBox, VMware, KVM) — NEVER use your main machine
  2. Host-only or isolated network adapter (NO internet access by default)
  3. Snapshot before analysis — restore after each sample
  4. Disable shared folders and clipboard (data exfiltration prevention)

Recommended sandbox stack:

Analysis VM (Windows 10/11 or Ubuntu):
├── FakeNet-NG or INetSim — Simulate network services
├── Wireshark — Capture network traffic
├── ProcessMonitor (Windows) / strace (Linux) — Monitor syscalls
├── Regshot (Windows) — Compare registry before/after
├── Autoruns (Windows) — Monitor persistence locations
└── Cuckoo/CAPE Agent — Automated collection

Network Layer:
└── Host-only adapter → no real internet → INetSim captures C2 attempts

Anti-anti-VM measures:

  • Install VMware Tools (some malware checks for missing tools)
  • Set reasonable RAM (4GB+) and CPU count (2+)
  • Add some benign user files and browser history
  • Set realistic screen resolution (1920x1080)
  • Remove obvious VM artifacts (registry keys, device names)

IOC Extraction & Output Format

For every analyzed sample, produce:

## Malware Analysis Report — [Sample Name]

**Hashes:**
- MD5:    [hash]
- SHA1:   [hash]
- SHA256: [hash]
- SSDeep: [fuzzy hash]

**Classification:** [Ransomware / RAT / Infostealer / etc.]
**Confidence:** [High / Medium / Low]
**Family:** [Family Name, if identified]
**First Seen:** [Date from TI sources]

**Network IOCs:**
