Supply Chain & Dependencies

Compromising MCP through malicious packages, dependency attacks, and supply chain infiltration, targeting the development and distribution infrastructure.

Overview

Supply chain attacks exploit the distributed nature of MCP development by compromising the tools, libraries, and distribution channels used to build and deploy MCP servers.

Attack Techniques

Malicious MCP Packages

Trojanized or malicious MCP servers distributed through official or unofficial channels.

Supply Chain Attacks

Compromise of MCP development or distribution infrastructure.

Dependency Vulnerabilities

Security flaws in third-party libraries and dependencies used by MCP servers.

Installer Spoofing

Fake or malicious MCP installers that compromise systems during installation.

Typosquatting

Malicious MCP servers with names similar to legitimate ones to deceive users.

Drift from Upstream

Unnoticed changes in tool behavior or code from upstream sources over time.

Malicious Dependency Inclusion

Inclusion of compromised or malicious dependencies in MCP server builds.

Impact Assessment

  • Severity: High to Critical
  • Likelihood: Medium
  • Detection Difficulty: High

Common Indicators

  • Unexpected package installations
  • Unusual dependency changes
  • Suspicious installer behavior
  • Modified upstream sources
  • Compromised build processes

General Mitigation Strategies

  1. Package Verification: Verify package integrity and authenticity
  2. Dependency Scanning: Regular vulnerability scanning of dependencies
  3. Supply Chain Monitoring: Monitor supply chain integrity
  4. Secure Development: Implement secure development practices
  5. Distribution Security: Secure package distribution channels

Detection Methods

  • Package integrity monitoring
  • Dependency vulnerability scanning
  • Supply chain analysis
  • Build process monitoring

This category contains 7 distinct attack techniques focused on compromising MCP systems through supply chain vulnerabilities.
