SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pybgpstream, bgpalerter.

What problem does it solve?

Organizations cannot tell whether their internet routes are actually protected against BGP prefix hijacking and route leaks until someone tests the defenses. This Skill provides a controlled, lab-based methodology to simulate hijack attacks, verify RPKI route origin validation, and confirm that BGP monitoring tools detect unauthorized announcements before a real attacker does.

Core Features & Use Cases

  • Isolated Lab Simulation: Builds Containerlab topologies with FRRouting routers to safely simulate more-specific prefix hijacks, exact-origin hijacks, and route leaks without touching production internet routing.
  • RPKI Validation Testing: Configures Routinator and FRR route-maps to verify that Route Origin Authorizations and ROV policies actually block invalid announcements, including edge cases like loose ROA max-lengths.
  • Monitoring & Detection: Deploys BGPalerter, pybgpstream, and RIPEstat queries to detect and analyze unauthorized route announcements in real time and historically.
  • Use Case: A cloud hosting company wants to confirm its RPKI deployment protects its customer prefixes. The Skill simulates a /25 more-specific hijack and an origin hijack in a lab, confirms ROV blocks them, identifies an unprotected prefix with no ROA, and produces a remediation report.

Quick Start

Ask the AI to build a Containerlab BGP lab and simulate a prefix hijack against AS65001's 10.0.0.0/24 to test whether RPKI validation blocks the attack.

FAQPage Schema
How do I simulate a BGP hijack in a lab environment?

Use Containerlab to deploy a topology of FRRouting containers representing legitimate, attacker, transit, and victim ASes. Announce a more-specific prefix (e.g., /25) from the attacker router and verify on the victim that traffic reroutes through the attacker AS using show ip bgp and show ip route.

Does RPKI protect against all BGP hijacking attacks?

No. RPKI route origin validation blocks invalid origin announcements but does not stop route leaks, which keep the legitimate origin AS. More-specific prefixes also bypass protection if the ROA max-length is set too loosely or unset.

What tools monitor BGP prefix hijacking in real time?

BGPalerter provides real-time alerts for prefix hijacks, route leaks, and RPKI status changes. For historical analysis, pybgpstream queries RouteViews and RIPE RIS data, while RIPEstat's API reports RPKI validation status per prefix.

Why does a more-specific prefix hijack bypass RPKI validation?

If a ROA's max-length is /25 or unset, an attacker's more-specific announcement (e.g., 10.0.0.0/25) validates as RPKI-Valid and wins by longest-prefix-match. Always check ROA max-length before concluding a prefix is protected.

Can I test BGP hijacking on the live internet?

No. Announcing prefixes you do not own on production networks is illegal and can cause widespread outages. All hijack simulation must occur in isolated environments like Containerlab, GNS3, or EVE-NG with written authorization for any real AS numbers.
