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 nld. Inferred improvements during Oct 2018: none inferred Source Address Validation issues inferred during Oct 2018: ASN Name First-Spoofed Last-Spoofed 44858 PROXSYS 2018-03-26 2018-10-23 28878 SIGNET 2018-06-27 2018-10-12 57494 ADMAN 2018-10-07 2018-10-07 201290 BlackGATE 2018-10-16 2018-10-16 Further information for these tests where we received spoofed packets is available at: https://spoofer.caida.org/recent_tests.php?country_include=nld&no_block=1 Please send any feedback or suggestions to spoofer-info@caida.org
