Hostcount for December 1995
by Mirjam Kuehne 04 Jan '96

04 Jan '96

Dear all, Please find below the last hostcount for 1995. The table shows an increase since November of almost 200,000 (or 10.0%) to a total of over 2,200,000 hosts in the DNS in Europe. We have not only hit but hurtled past the 2 Million boundary :-) We have a new champion: FI shows the highest increase with over 70,000 hosts more than in November. Certain zones this time have shown a decline in numbers were previously their numbers were seen to increase. This could be due to server neglect :) over Christmas. The hostcount can also be found under ftp://ftp.ripe.net/ripe/hostcount/ The graphical version of the hostcount can be found at ftp://ftp.ripe.net/ripe/hostcount/RIPE-Hostcount-{Mo,Qu}.eps The translation of the country codes can be found at ftp://ftp.ripe.net/iso3166-countrycodes I would like to thank all people who help me to create the hostcount every month by counting hosts locally: at Gerhard Winkler <Gerhard.Winkler(a)univie.ac.at> be Herman Moons <Herman.Moons(a)CS.kuleuven.ac.be> ch Christoph Graf <graf(a)chx400.switch.ch> cy Panagiotis Tzounakis <pj(a)ics.forth.gr> cz Jiri Orsag <Jiri.Orsag(a)eunet.cz> de Peter Koch <pk(a)TechFak.Uni-Bielefeld.DE> dk Robert Martin-Legene <robert(a)dknet.dk> es Jose Sanchez-Seco <jose.sanchez(a)rediris.es> fi Petri Ojala <ojala(a)eunet.fi> fr Benoit Grange <grange(a)sagres.inria.fr> gr Dimitris Zisiadis <zisiadis(a)forthnet.gr> hr Ivan Maric <Ivan.Maric(a)stribor.srce.hr> ie Mike Norris <mnorris(a)dalkey.hea.ie> il Sason Levi <sason(a)NetVision.net.il> it Antonio_Blasco Bonito <bonito(a)nis.garr.it> no Havard Eidnes <Havard.Eidnes(a)runit.sintef.no> pt Graca Carvalho <fccn(a)dns.pt> ru Andrey Dobrotsvetov <adbr(a)argo.net.kiae.su> sk Ivan Lescak <Ivan.Lescak(a)Slovakia.EU.net> Lubos Elias <Lubos.Elias(a)uakom.sk> tr Yener Yigit <yener(a)knidos.cc.metu.edu.tr> uk JANET NOSC <nosc(a)nosc.ja.net> If you have any questions, please don't hesitate to contact me.

If, after the RIPE meeting, you want to stay some additional days we can invite you for some 'technical meetings' after the RIPE meeting (wink wink ;-). Furthermore, please give also your full name, birth date and passport number. If we mention these data in our invitation to you, it could facilitate getting visa.

Hundreds of sites have been attacked, and many of the attacks have been successful, resulting in root compromises at the targeted sites. We continue to receive reports, and we believe that more attacks are going undetected. ********************************************************************** All the vulnerabilities exploited in these attacks are known, and are addressed by CERT advisories (see Section III). ********************************************************************** We urge everyone to obtain these advisories and take action to ensure that systems are protected against these attacks. Also, please feel free to redistribute this message. As we receive additional information relating to this advisory, we will place it in ftp://info.cert.org/pub/cert_advisories/CA-95:18.README We encourage you to check our README files regularly for updates on advisories that relate to your site. ----------------------------------------------------------------------------- I. Description Intruders are doing the following: - using automated tools to scan sites for NFS and NIS vulnerabilities - exploiting the rpc.ypupdated vulnerability to gain root access - exploiting the loadmodule vulnerability to gain root access - installing Trojan horse programs and packet sniffers - launching IP spoofing attacks II. Impact Successful exploitation of the vulnerabilities can result in unauthorized root access. III. Solution The CERT staff urges you to immediately take the steps described in the advisories and README files listed below. Note that it is important to check README files as they contain updated information we received after the advisory was published. a. Using automated tools to scan sites for NFS and NIS vulnerabilities * CA-94:15.NFS.Vulnerabilities * CA-94:15.README * CA-92:13.SunOS.NIS.vulnerability b. Exploiting the rpc.ypupdated vulnerability to gain root access * CA-95:17.rpc.ypupdated.vul * CA-95:17.README c. Exploiting the loadmodule vulnerability to gain root access * CA-93:18.SunOS.Solbourne.loadmodule.modload.vulnerability * CA-95:12.sun.loadmodule.vul * CA-95:12.README d. Installing Trojan horse programs and packet sniffers * CA-94:01.ongoing.network.monitoring.attacks * CA-94:01.README e. Launching IP spoofing attacks * CA-95:01.IP.spoofing * CA-95:01.README The CERT advisories and README files are available from ftp://info.cert.org/pub/cert_advisories If you find a compromise, please complete the Incident Reporting Form that we have provided in the appendix of this advisory, and return the form to cert(a)cert.org. This completed form will help us better assist you. Note: Because of our workload, we must ask you not to send log files of activity, but we would be happy to work with you as needed on how to interpret data that you may collect. Also, the CERT staff can provide guidance and advice, if needed, on how to handle incidents and work with law enforcement. If you see activity that indicates an attack is in progress, we encourage you to contact other sites involved and the service providers, as well as the CERT Coordination Center. --------------------------------------------------------------------------- Contacting the CERT Coordination Center For sensitive information, please use encrypted email.
