25 July 2010 A2 sends: Cesium.clock.org and the IP it resides aren't owned by any government agency. The IP range is registered with ARIN by Shimomura under the name "Los Alamos National Laboratory". Somehow that slipped through ARIN QA. It's not a legitimate LANL net handle. Cesium.clock.org is a popular shell box for Bay Area hackers. A3 sends: This is not as cloak & dagger as it seems. That network is used/operated by UC San Diego (that is their address in the registration info). 24 July 2010 A sends: Adrian Lamo hangs out all the time on a server called cesium.clock.org, with IP address [192.5.16.65]. This IP space is registered with ARIN to a network called "LANLLAND" belonging to the Los Alamos National Laboratory. Strangely, and unlike all other LANL networks, reverse DNS mapping for this network is provided by ARPA.NET -- an official-sounding network which is really the private domain of Tsutomu Shimomura. You'll remember Shimomura as the dork who "took down" hacker Kevin Mitnick, leading to an extensive campaign by 2600 Magazine for his release, and a later campaign to halt production of the "Takedown" movie aggrandizing Shimomura. Lamo works for 2600 and maintains their Facebook group. Why is Adrian Lamo hanging out on the network of the Los Alamos National Laboratory if he has no affiliation with the government? Is Lamo accessing 2600 servers from a computer or network controlled by Tsutomu Shimomura? Good question for 2600's Emmanuel Goldstein. https://ws.arin.net/whois/?queryinput=192.5.16.65 OrgName: Los Alamos National Laboratory OrgID: LANL-1 Address: 9500 Gilman Drive MC 0505 City: La Jolla StateProv: CA PostalCode: 92093-0505 Country: US NetRange: 192.5.16.0 - 192.5.16.255 CIDR: 192.5.16.0/24 NetName: LANLLAND NetHandle: NET-192-5-16-0-1 Parent: NET-192-0-0-0-0 NetType: Direct Assignment NameServer: SRI-NIC.ARPA.NET NameServer: NS1.ARPA.NET NameServer: NS4.ARPA.NET Comment: RegDate: 1983-05-09 Updated: 2000-05-23 RTechHandle: ARPA-HM-ARIN RTechName: American Regional Providers Association RTechPhone: +1-858-534-5050 RTechEmail: hostmaster[at]arpa.net OrgTechHandle: ARPA-HM-ARIN OrgTechName: American Regional Providers Association OrgTechPhone: +1-858-534-5050 OrgTechEmail: hostmaster[at]arpa.net http://www.robtex.com/dns/arpa.net.html#whois Registrant: American Regional Providers Association 9500 Gilman Drive, MC 0505 La Jolla, CA 92093-0505 US Domain Name: ARPA.NET Administrative Contact, Technical Contact, Zone Contact: American Regional Providers Association Shimomura, Tsutomu 9500 Gilman Drive, MC 0505 La Jolla, CA 92093-0505 US 858-534-5050 tsutomu[at]sdsc.edu
