Endigest AI Core Summary
This post analyzes a BGP route leak involving Venezuela's state-run ISP CANTV (AS8048), arguing the anomaly was likely due to poor routing policy rather than malicious intent.
•AS8048 leaked routes from provider AS6762 (Sparkle) to AS52320 (GlobeNet), involving prefixes originated by AS21980 (Dayco Telecom), a customer of AS8048
•The leaked routes were heavily AS-path prepended, making them less attractive — inconsistent with a deliberate man-in-the-middle attack
•Eleven similar route leak events by AS8048 were recorded since December, suggesting a persistent misconfiguration rather than a one-time targeted action
•The leaks occurred over 12 hours before U.S. military action in Venezuela, weakening the theory of a politically motivated BGP manipulation
•
RFC9234 and the Only-to-Customer (OTC) attribute are proposed as technical mitigations; RPKI ROV would not have prevented this path-based anomaly
