Phase 1: Demonstrate Attack

+
    +
  1. Click šŸ”„ Switch Registry to load the poisoned registry
    2. +
  2. Observe the COMPROMISED warning appear
    3. +
  3. Capture the flag: {FLAG_ASI04}
    4. +
  4. Check http://localhost:8666/dashboard for exfiltrated data
    5. +
+ +

Phase 2: Enable Mitigation

+
    +
  1. Click šŸ”„ Switch Registry to revert to legitimate MCP
    2. +
  2. Click šŸ›”ļø Toggle Provenance Checking to enable mitigation
    3. +
  3. Observe status change to ENABLED
    4. +
+ +

Phase 3: Test Mitigation

+
    +
  1. Click šŸ”„ Switch Registry to attempt loading poisoned registry
    2. +
  2. šŸŽÆ Agent REFUSES to load untrusted MCP!
    3. +
  3. Check "Load Status Details" - evil MCP blocked with reason
    4. +
  4. Supply chain attack prevented!

Phase 1: Demonstrate Attack

+
    +
  1. Click šŸ”„ Switch Registry to load the poisoned registry
    2. +
  2. Observe the COMPROMISED warning appear
    3. +
  3. Capture the flag: {FLAG_ASI04}
    4. +
  4. Check http://localhost:8666/dashboard for exfiltrated data
    5. +
+ +

Phase 2: Enable Mitigation

+
    +
  1. Click šŸ”„ Switch Registry to revert to legitimate MCP
    2. +
  2. Click šŸ›”ļø Toggle Provenance Checking to enable mitigation
    3. +
  3. Observe status change to ENABLED
    4. +
+ +

Phase 3: Test Mitigation

+
    +
  1. Click šŸ”„ Switch Registry to attempt loading poisoned registry
    2. +
  2. šŸŽÆ Agent REFUSES to load untrusted MCP!
    3. +
  3. Check "Load Status Details" - evil MCP blocked with reason

Phase 1: Demonstrate Attack

-
    -
  1. Click šŸ”„ Switch Registry to load the poisoned registry
    2. -
  2. Observe the COMPROMISED warning appear
    3. -
  3. Capture the flag: {FLAG_ASI04}
    4. -
  4. Check http://localhost:8666/dashboard for exfiltrated data
    5. -
- -

Phase 2: Enable Mitigation

-
    -
  1. Click šŸ”„ Switch Registry to revert to legitimate MCP
    2. -
  2. Click šŸ›”ļø Toggle Provenance Checking to enable mitigation
    3. -
  3. Observe status change to ENABLED
    4. -
- -

Phase 3: Test Mitigation

-
    -
  1. Click šŸ”„ Switch Registry to attempt loading poisoned registry
    2. -
  2. šŸŽÆ Agent REFUSES to load untrusted MCP!
    3. -
  3. Check "Load Status Details" - evil MCP blocked with reason
    4. -
  4. Supply chain attack prevented!
