Security Policy

The XHorse Multi-PROG Ultimate Kit is designed to support legitimate, authorized automotive shop operations. This document outlines security policies, content classification, and responsible handling procedures.

Security-Sensitive Content Policy

This repository may contain private, authorized documentation and workflow references for:

Immobilizer & Key Security

• PIN, CS, MAC, ISN, or password extraction
• Seed-key or security-access algorithms
• Real immobilizer memory offsets or locations
• Key or transponder cloning techniques
• Credential or security token generation
• All-keys-lost programming procedures
• Immobilizer disabling, deletion, or bypassing
• Virginization or synchronization patches
• Master key generation

Vehicle Security

• Odometer correction or module-replacement documentation
• Theft-enabling functionality as a controlled internal reference topic
• Unauthorized vehicle access or start bypass
• ECU replacement without recalibration
• Instrument cluster manipulation

Cryptographic Material

• Real cryptographic algorithms or constants
• Security-access sequences or checksums
• Proprietary vendor security transforms
• OEM-specific security material

All of the above remain restricted to private, permissioned use within this repository and must not be published as public operational instructions or redistributed externally.

Customer Data

• Real vehicle identification numbers (VINs)
• Real customer data or vehicle dumps
• Confidential calibration values
• Production vehicle security information
• Real immobilizer keys or secrets

Content Classification

Official

• Xhorse Multi-PROG official documentation and releases
• Official mirrors and vendor-provided links
• Published, verified APIs and host signatures

Verified Open Source

• GitHub repositories with proper licenses
• Peer-reviewed academic content
• Published technical specifications

Community Source

• Forum discussions and shared experiences
• Blog posts from known contributors
• Community-maintained tools and libraries
• Treated with caution; requires verification

Unverified

• Cloud-drive links and file shares
• Archived or third-party mirrors
• Anonymous or unknown sources
• Quarantined; requires review before use

Generated Locally

• Content created in this repository
• Synthetic test vectors
• Safe examples and templates

Quarantined

• Malicious or suspicious code
• Obfuscated or unclear functionality
• Files with confirmed or likely dangerous patterns
• Unverifiable content with high security risk
• Stored in 99_Quarantine/ with metadata

File Trust Analysis

Suspicious Patterns

Scripts are flagged if they contain:

• eval() — Dynamic code execution
• Function() — Runtime function creation
• exec(), execFile(), spawn() — System command execution
• Proxy or network functionality without clear purpose
• Obfuscation or Base64-encoded content
• Missing source attribution

Quarantine Criteria

Files are quarantined if they exhibit:

• Confirmed malicious patterns
• Unverifiable origins
• License violations
• Copyright infringement risk
• Suspected malware or trojans
• Extreme security risk

Verification Process

All collected third-party scripts undergo:

1. Static analysis — Pattern scanning, signature checking
2. Manual review — Purpose verification, code inspection
3. Attribution check — Source preservation, license verification
4. Hash recording — SHA-256 computation and storage
5. Classification — Trust level assignment
6. Quarantine (if needed) — Safe isolation with metadata

Reporting Security Issues

Responsible Disclosure

If you discover:

• Malicious code in the repository
• Security bypass instructions inappropriately included
• Credential/key leaks or sensitive material
• Suspicious scripts requiring review
• Documentation errors enabling unsafe practices

Please report privately:

1. Do not open a public issue
2. Contact the repository maintainer with:
   • Description of the security concern
   • File path and line numbers
   • Impact assessment
   • Suggested remediation
3. Allow 14 days for response and remediation
4. Coordinate disclosure before public announcement

What NOT to Report

• Documentation typos or formatting
• Missing links or broken references
• Feature requests
• General questions

Use the issue tracker for these.

Using This Repository Safely

For Legitimate Shop Operations

1. Verify authorization — Ensure you own or are authorized to service the vehicle/module
2. Use read-only first — Start with data inspection, not modification
3. Test synthetically — Validate with test data before production use
4. Verify signatures — Cross-check SHA-256 hashes for downloaded content
5. Document everything — Keep audit trails, backups, and change records
6. Review source code — Understand scripts before execution
7. Isolate test environment — Use controlled, current-limited bench power
8. Preserve originals — Keep immutable backups of all original dumps

For Research & Learning

1. Use official documentation — Multi-PROG Help is the source of truth
2. Validate examples — Test against known, public vectors only
3. Avoid real data — Use synthetic, non-confidential fixtures
4. Isolate execution — Run on isolated hardware, never production systems
5. Preserve attribution — Credit all sources properly
6. Respect licenses — Follow all applicable open-source and commercial terms

What NOT to Do

• ❌ Download and run unreviewed third-party scripts
• ❌ Execute suspicious code on production modules
• ❌ Share real vehicle dumps publicly
• ❌ Extract credentials or security material
• ❌ Modify scripts without understanding their function
• ❌ Use this kit for unauthorized vehicle access or fraud
• ❌ Bypass security measures or immobilizer protections
• ❌ Circumvent manufacturer security procedures

Legal Compliance

Authorization Requirements:

• All use must comply with local automotive repair regulations
• Module access/modification requires proof of ownership or explicit authorization
• Some jurisdictions require specific licensing or certification
• Consult local laws and OEM policies before proceeding

Intellectual Property:

• Respect all copyrights, patents, and trademarks
• Follow open-source license terms (MIT, GPL, Apache, etc.)
• Preserve author attribution for all included content
• Do not redistribute proprietary content without permission

Data Privacy:

• Never share real customer data, VINs, or vehicle secrets
• Redact all personally identifiable information
• Comply with GDPR, CCPA, and local data protection laws
• Maintain confidentiality of shop procedures and customer vehicles

Repository Security Practices

Files & Hashing

• All files are scanned and cataloged with SHA-256 hashes
• Inventory records are maintained in 14_Repository_Review/
• Hash mismatches indicate file corruption or tampering
• Third-party content is never modified (only sourced and linked)

Version Control

• The .git directory is preserved and never rewritten
• No secrets, credentials, or sensitive material are committed
• All changes are auditable through Git history
• Repository can be verified against published hashes

Quarantine Procedures

• Suspicious files are moved to 99_Quarantine/
• Original paths are documented with reason for quarantine
• Quarantined files are never executed or imported
• Metadata includes hash, source, analysis date, and risk assessment

Scanning & Analysis

• Repository is scanned for:
  • Suspicious code patterns
  • Known malware signatures
  • License violations
  • Sensitive data exposure
  • Structural integrity issues
• Reports are generated in 14_Repository_Review/
