Question 1

Why do valid ROAs fail to stop some BGP hijacking attacks?

Accepted Answer

Valid ROAs fail when attackers spoof ASNs to avoid invalid states. Only approximately 25% of systems actively enforce filtering, allowing these stealthy announcements to propagate through non-enforcing networks successfully.

Question 2

How long did the specific hijack events last in the 2025 case study?

Accepted Answer

The three hijack events lasted merely five to twenty minutes each. While over 50% of prefixes possess ROA coverage, these short bursts exploited weak identity verification to redirect traffic silently.

Question 3

What gap exists between RPKI signature coverage and actual network enforcement?

Accepted Answer

A massive gap exists because many networks do not actively filter invalid routes. Although over 50% of prefixes have ROAs, only 25% of systems enforce them, leaving infrastructure vulnerable to spoofing.

Question 4

Can attackers bypass RPKI by exploiting upstream provider provisioning processes?

Accepted Answer

Yes, attackers bypass RPKI by using social engineering to fool upstream providers. Only 43.17% of IPv4 prefixes enforce validation, meaning many providers accept fraudulent peering requests without rigorous identity checks.

Question 5

How do short announcement bursts help attackers evade detection during hijacks?

Accepted Answer

Short bursts make traffic diversion difficult to trace before mitigation occurs. While over 50% of prefixes possess ROA coverage, these rapid attacks exploit the fact that only 25% enforce filtering.
