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 Aug 2021: none inferred Source Address Validation issues inferred during Aug 2021: ASN Name First-Spoofed Last-Spoofed 42004 ULGRP 2016-11-07 2021-08-25 211552 2021-08-04 2021-08-04 60672 SC 2021-08-04 2021-08-19 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 Please send any feedback or suggestions to [email protected]
