BGP Hijacking (Route Hijacking, Prefix Hijacking)
BGP Hijacking or Route Hijacking is the illegal takeover of ranges of IP addresses, by corrupting Internet Routing Tables used within the BGP (Border Gateway Protocol).
A hijacker will announce and reroute network traffic for smaller ranges of a network without authorization from the owner of those addresses.
By announcing smaller ranges than the ASN, the smaller range will take priority in routing over a larger network containing the range.
