Unless I'm mis-reading this (or perhaps GBLX read Kreb's story and said good-bye to Atrivo/Intercage), it looks like they are no longer their upstream: http://cidr-report.org/cgi-bin/as-report?as=AS27595&v=4&view=2.0 Marc SANS ISC -----Original Message----- From: Gadi Evron [mailto:ge@linuxbox.org] Sent: Friday, August 29, 2008 4:02 PM To: nanog@merit.edu Subject: Washington Post: Atrivo/Intercage, why are we peering with the American RBN? Hi all. This Washington Post story came out today: http://voices.washingtonpost.com/securityfix/2008/08/report_slams_us_host_as _major.html In it, Brian Krebs discusses the SF Bay Area based Atrivo/Intercage, which has been long named as a bad actor, accused of shuffling abuse reports to different IP addresses and hosting criminals en masse, compared often to RBN in maliciousness. "The American RBN", if you like. 1. I realize this is a problematic issue, but when it is clear a network is so evil (as the story suggests they are), why are we still peering with them? Who currently provides them with transit? Are they aware of this news story? If Lycos' make spam not war, and Blue Security's blue frog were ran out of hosting continually, this has been done before to some extent. This network is not in Russia or China, but in the silicon valley. 2. On a different note, why is anyone still accepting their route announcements? I know some among us re-route RBN traffic to protect users. Do you see this as a valid solution for your networks? What ASNs belong to Atrivo, anyway? Anyone has more details as to the apparent evilness of Atrivo/Intercage, who can verify these reports? As researched as they are, and my personal experience aside, I'd like some more data before coming to conclusions.
