Abstract
Method, system and computer-readable medium to locate a prefix hijacker of a destination prefix within a one-hop neighborhood on a network. The method includes generating one-hop neighborhoods from autonomous system (AS)-level paths of plural monitors to a destination prefix. The method also includes determining a suspect set of AS identifiers resulting from a union of the one-hop neighborhoods. The method further includes calculating a count and a distance associated with each AS identifier of the suspect set. The count indicates how often the AS identifier appeared in the one-hop neighborhoods. The distance indicates a total distance from the AS identifier to AS identifiers associated with the plural monitors. Yet further, the method includes generating a one-hop suspect set of AS identifiers from the suspect set that have highest counts and highest distances.
