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 gbr. Inferred improvements during Sep 2020: none inferred Source Address Validation issues inferred during Sep 2020: ASN Name First-Spoofed Last-Spoofed 20860 IOMART 2016-02-10 2020-09-08 9009 M247 2017-01-10 2020-09-02 62240 Clouvider 2017-10-20 2020-09-03 Further information for these tests where we received spoofed packets is available at: https://spoofer.caida.org/recent_tests.php?country_include=gbr&no_block=1 Source Address Validation issues inferred during Sep 2020 using open resolver tests: ASN Name Last-Detected 13037 ZEN 2020-09-25 9009 M247 2020-09-16 36351 SOFTLAYER 2020-09-05 5089 NTL 2020-09-04 8586 OBSL 2020-09-04 8851 EDGE 2020-09-04 29129 VISPA-ASN 2020-09-01 Further information for these tests is available at: https://spoofer.caida.org/ornog.php?country_include=gbr Please send any feedback or suggestions to [email protected]
