Method, system and computer-readable device to locate a prefix hijacker of a destination prefix within a one-hop neighborhood. The method includes generating one-hop neighborhoods from autonomous system-level paths associated with a plurality of monitors to a destination prefix. The method also includes determining a suspect set of autonomous system identifiers resulting from a union of the one-hop neighborhoods. The method further includes calculating a count and a distance associated with each autonomous system identifier in the suspect set of autonomous system identifiers. The count represents how often an autonomous system identifier appears in the one-hop neighborhoods. The distance represents a total number of autonomous system identifiers from the autonomous system identifier to autonomous system identifiers associated with the plurality of monitors. Yet further, the method includes generating a one-hop suspect set including autonomous system identifiers in the suspect set that have a greatest sum of the count and the distance.
A method of locating a prefix hijacker within a one-hop neighborhood, the method comprising:
A prefix hijacker location system, the system comprising:
A computer-readable storage device comprising instructions that, when executed by a processor, cause the processor to perform operations comprising:
