DS_Store Crawler Parser

DS_Store Crawler Parser is a specialized security tool designed to parse and crawl .DS_Store files that are exposed publicly on web servers. This tool helps security researchers and penetration testers identify directory structures and sensitive files that may be inadvertently exposed through these macOS system files.

Project Overview

.DS_Store files are created automatically by macOS Finder to store metadata about folder contents, including file names, positions, and other attributes. When these files are accidentally exposed on web servers, they can reveal sensitive information about the server’s directory structure, potentially exposing hidden files and directories.

Key Features

🔍 .DS_Store File Parsing

• Metadata Extraction: Parse .DS_Store files to extract directory and file information
• Entity Identification: Identify various entities and file structures from the parsed data
• Recursive Crawling: Automatically discover and parse nested .DS_Store files
• Public Exposure Detection: Specifically designed to work with publicly exposed .DS_Store files

🕷️ Automated Crawling

• Recursive Discovery: Automatically find and process .DS_Store files within discovered directories
• Base File Processing: Start with a base .DS_Store file and expand from there
• Continuous Discovery: Rinse and repeat the process for newly discovered directories
• Comprehensive Coverage: Ensure thorough exploration of exposed directory structures

🛡️ Security Research Focus

• Information Disclosure: Identify potential information disclosure vulnerabilities
• Directory Enumeration: Map out server directory structures
• Hidden File Discovery: Find files that might not be directly accessible
• Penetration Testing: Support security assessments and vulnerability research

How It Works

1. Base File Processing

The tool starts by downloading and parsing a base .DS_Store file to identify various entities and directory structures.

2. Recursive Discovery

Once the initial parsing is complete, the tool identifies directories and subdirectories that may contain additional .DS_Store files.

3. Continuous Crawling

For each discovered .DS_Store file, the tool:

• Downloads the file
• Parses its contents
• Identifies new directories and files
• Recursively processes any new .DS_Store files found

4. Information Aggregation

The tool aggregates all discovered information to provide a comprehensive view of the exposed directory structure.

Security Implications

Common Vulnerability

.DS_Store files are frequently exposed on web servers due to:

• Accidental Uploads: Developers uploading entire project directories
• Misconfigured Servers: Web servers serving hidden files
• Lack of Awareness: Unawareness of .DS_Store file contents
• Insufficient Filtering: Web servers not filtering system files

Potential Risks

Exposed .DS_Store files can reveal:

• Directory Structures: Complete folder organization
• Hidden Files: Files not directly accessible via web
• Sensitive Information: Configuration files and credentials
• Attack Vectors: Potential entry points for further exploitation
