Perhaps it is a false positive from PHAS since IAR, watchmy.net and RIPE
RIS don't see it either?
Doing a quick dump of the BGP RIB, I find the following AS paths for these
2 ASNs (hundreds of prefixes):
3549 9002 8997 (upstream in Russia)
1299 20485 8997 (upstream in Russia)
1299 8342 12389 8997 (upstream in Russia)
3058 3267 (upstream in Russia)
3549 9002 3267 8482 (upstream in Russia)
2603 3267 28811 44863 (upstream in Sweden)
The question is, is 8997 originating or is 3267 originating and 8997 is
just an unwitting transit? The PHAS alerts are unclear on this issue.
Also, maybe the prefixes hijacks are only getting thru one upstream and
not the rest. Can anyone see the full AS path these hijacks appear with?
Then at least we can start contacting their upstreams to do a better job
of filtering.
