MALWARE ANALYSIS TOOLKIT

Dark Arts Vault - Advanced Binary Analysis Suite

Hex Decoder

Purpose: Convert hexadecimal data to ASCII text. Essential for analyzing hex dumps from memory, network captures, or binary files. Malware often hides strings in hex format to evade detection.

Usage: Paste hex values (with or without spaces, 0x prefix). Printable characters are highlighted in green, non-printable in red.

Printable ASCII (32-126)
Non-Printable

Base64 Encoder/Decoder

Purpose: Base64 encoding is commonly used in malware to obfuscate payloads, commands, and configuration data. It's also used in web attacks, email attachments, and data exfiltration.

Padding: Base64 uses '=' for padding when the input length isn't divisible by 3. URL-safe variant replaces '+' with '-' and '/' with '_'.

Tip: Base64 strings often end with '=' or '=='. Look for patterns like "TVq" (MZ header) or "JVB" (PDF header) which indicate encoded files.

String Analyzer

Purpose: Extract printable ASCII strings from binary data. Critical for finding URLs, IPs, file paths, and commands embedded in malware samples.

Pattern Detection: Automatically highlights suspicious patterns like C2 servers, registry keys, and file paths commonly used by malware.

Hash Calculator

Purpose: Calculate cryptographic hashes for malware identification and IOC tracking. Hashes are unique fingerprints used to identify known malicious files.

Hash Types:
  • MD5: Fast but deprecated for security. Still used in malware databases.
  • SHA-1: More secure than MD5. Common in older threat intelligence.
  • SHA-256: Current standard for file identification and integrity.
MD5: -
SHA-1: -
SHA-256: -
Malware Analysis Use: Hash unknown files and search them on VirusTotal, Hybrid Analysis, or other threat intelligence platforms to check for known malware signatures.

XOR Decoder

Purpose: XOR (exclusive OR) is one of the most common encryption methods used in malware for obfuscating strings, configuration data, and payloads.

Brute Force Mode: Tests all 256 single-byte keys (0x00-0xFF) and scores results based on printable ASCII characters. High scores indicate likely decryption success.

Tip: Look for readable strings in brute force results. High scores (>70%) usually indicate successful decryption. Multi-byte keys require known plaintext attacks.

Entropy Calculator

Purpose: Shannon entropy measures data randomness (0-8 bits per byte). Essential for detecting encryption, compression, or packed malware.

Interpretation:
  • 0-3: Low entropy - Plain text, repetitive data
  • 3-6: Medium entropy - Compressed or structured data
  • 6-8: High entropy - Encrypted or packed (suspicious!)

Data Size: - bytes
Malware Analysis: Packed/encrypted malware sections show high entropy (>7.0). Compare entropy across different file sections to find packed code.

IOC Extractor

Purpose: Automatically extract Indicators of Compromise (IOCs) from logs, reports, or malware output. IOCs are forensic artifacts that indicate potential intrusions.

Extracted IOCs: IPv4 addresses, domains, URLs, email addresses, MD5/SHA1/SHA256 hashes.

Defanging: Converts IOCs to safe format (e.g., malware[.]com, 192.168.1[.]1) to prevent accidental clicks/execution.

Workflow: Extract IOCs → Defang for sharing → Search on threat intelligence platforms → Add to blocklists/SIEM alerts.
