hi folks, I tried to detect bgp hijack, my way is pretty straitforward as below:

I downloaded IP/ASN data set from IRR(ripe/arin/apnic) and store them in search engine(support partial/prefix query), then I crawled bgp stream data from routeviews, if I found the original asn was different than IRR, then the

hijack event would be caught.

My result can be found here ipiphistory.com
