Spoofer Report for NANOG for Dec 2022
by CAIDA Spoofer Project 08 Jan '23

08 Jan '23

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can. Inferred improvements during Dec 2022: ASN Name Fixed-By 400328 2022-12-25 208287 BAK 2022-12-26 Further information for the inferred remediation is available at: https://spoofer.caida.org/remedy.php Source Address Validation issues inferred during Dec 2022: ASN Name First-Spoofed Last-Spoofed 209 CENTURYLINK-US-LEGACY-QWEST 2016-08-16 2022-12-28 6128 CABLE-NET-1 2016-09-03 2022-12-22 20412 CLARITY-TELECOM 2016-09-30 2022-12-31 6181 FUSE-NET 2016-10-10 2022-12-31 271 BCNET 2016-10-24 2022-12-30 12083 WOW-INTERNET 2016-11-09 2022-12-30 14576 HOSTING-SOLUTIONS 2016-11-20 2022-12-28 852 ASN852 2017-04-16 2022-12-29 33452 RW 2018-09-19 2022-12-31 21804 ACCESS-SK 2019-06-09 2022-12-31 398836 NP-NETWORKS 2021-03-12 2022-12-25 22773 ASN-CXA-ALL-CCI-22773-RDC 2021-10-24 2022-12-28 397086 LAYER-HOST-HOUSTON 2022-06-16 2022-12-18 400517 2022-10-03 2022-12-07 11976 FIDN 2022-11-16 2022-12-31 12183 TALKIE-COMMUNICATIONS 2022-12-10 2022-12-27 33185 HIVE-DATA-CENTER 2022-12-11 2022-12-25 399296 2022-12-30 2022-12-30 Further information for these tests where we received spoofed packets is available at: https://spoofer.caida.org/recent_tests.php?country_include=usa,can&no_block… Please send any feedback or suggestions to spoofer-info(a)caida.org

GTT blocking IPv4 address 128.31.0.39
by Neel Chauhan 03 Jan '23

03 Jan '23

Hi, I am a customer of ReliableSite in their New Jersey location, and RS uses GTT as a transit ISP, along with Tata and Comcast. GTT appears to be blocking the IPv4 address 128.31.0.39, and RS' BGP uses GTT for 128.31.0.39. neel@t1:~ % traceroute 128.31.0.39 traceroute to 128.31.0.39 (128.31.0.39), 64 hops max, 40 byte packets 1 45.150.XXX.1 (45.150.XXX.1) 4.828 ms 4.557 ms 5.916 ms 2 * * * ^C neel@t1:~ % Hop #2 which is generally the transit provider, GTT (which handles this route). Note: 45.150.XXX.1 is because it's a subnet I brought in, this is the only ReliableSite hop. The 128.31.0.0/24 doesn't appear to be blocked as a whole, only that 128.31.0.39. See below: neel@t1:~ % traceroute 128.31.0.1 traceroute to 128.31.0.1 (128.31.0.1), 64 hops max, 40 byte packets 1 45.150.XXX.1 (45.150.XXX.1) 0.241 ms 0.220 ms 9.362 ms 2 ae9-300.cr2-nyc4.ip4.gtt.net (209.120.147.121) 1.605 ms 0.853 ms 1.173 ms 3 ae3.cr1-nyc2.ip4.gtt.net (89.149.129.194) 5.488 ms 6.471 ms 1.451 ms 4 be3088.ccr31.jfk04.atlas.cogentco.com (154.54.11.57) 1.604 ms 1.726 ms * 5 be3363.ccr42.jfk02.atlas.cogentco.com (154.54.3.125) 1.802 ms 1.771 ms 1.708 ms 6 be3472.ccr32.bos01.atlas.cogentco.com (154.54.46.33) 7.082 ms 7.268 ms 7.249 ms 7 38.104.186.186 (38.104.186.186) 7.017 ms 7.247 ms 6.987 ms 8 dmz-rtr-1-external-rtr-3.mit.edu (18.0.161.13) 7.010 ms 7.001 ms 6.996 ms 9 dmz-rtr-2-dmz-rtr-1-2.mit.edu (18.0.162.6) 7.033 ms 7.294 ms dmz-rtr-2-dmz-rtr-1-1.mit.edu (18.0.161.6) 7.073 ms 10 guest.default.csail.mit.edu (128.31.0.1) 9.011 ms 7.484 ms 7.551 ms neel@t1:~ % As you can see here, GTT handles other 128.31.0.39 IPs fine as seen in hop #2. ReliableSite says they don't block the IP address, but I don't have any contact at GTT or MIT. My home ISP, Lumen/CenturyLink/Level 3 does not block 128.31.0.39. 128.31.0.39 is a Tor directory authority IP, which is usually a phonebook of Tor relays. There are 9 in the world and the other 8 are unblocked from ReliableSite. Yes, I know Tor is all this 'bad stuff' but the reality is that 99% of Tor users use it like a VPN, speaking as a Tor exit operator and code contributor myself. Exit abuse complaints were super common 5-8 years ago but are now super rare. If someone works at GTT, can 128.31.0.39 be unblocked? Best, -Neel --- https://www.neelc.org
