[SANOG] Spoofer Report for SANOG for Jul 2025

[CAIDA Spoofer Project]

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 afg, bgd, btn, lka, mdv, npl, pak.
