Thanks for that info Andree. The only valid peer I see on the list would be HE. We do not peer with any of the others listed. Kenneth On Fri, Jan 11, 2013 at 8:46 AM, Andree Toonk <andree+nanog@toonk.nl> wrote:
Hi, Here's a quick summary of what we saw at BGPMon.net.
At 2013-01-11 14:14:13 we saw announcements (seemingly) originated by 26347, for prefixes normally announced by other ASn's (origin change / hijack).
This seems to have affected 112 prefixes for 110 ASn's [1], including Rogers, Tata, Sprint, Ziggo, Verizon, KPN, Vodafone, CloudFlare, XS4ALL, AT&T, Bell Canada and many more. Most of these were new more specific(!) announcements.
With regards to next-hop ASN's (peers). It seems this hijack was propagated via 12 unique (AS26347) peers [1]
A quick look at the prefix that was mentioned by Jeff, 150.182.208.0/20 (more specific of 50.182.192.0/18) The first announcement for this prefix was seen at 2013-01-11 14:14:28 and withdrawn at 2013-01-11 15:20:57. It was detected by 42 unique peers.
some example paths: 271 6939 26347 5580 26347| 37312 5713 6939 26347 1126 24785 12989 26347
[1] I've posted some details (Unique next-hop ASN's and affected origin ASN's), check if your AS was affected here: http://portal.bgpmon.net/data/hijack20130111.txt
Cheers, Andree

Not sure how widespread their "leakage" may be, but Dreamhost just hijacked one of my prefixes...

Anyone have a contact there? ASinfo gives netops@dreamhost.com where I have submitted a report, but so far no joy...
