Evidence: user=unknown src_port=44690; user=unknown src_port=44694; user=unknown src_port=44708; user=unknown src_port=47644. TCP port scan against non-whitelisted ports on the same router: 4 SYN packet(s) logged by nftables within a 300s window starting 2026-09-18 20:20 (dst ports: 22; nftables rate-limits logging, actual scan may be larger). Evidence: dst_port=22 src_port=44684; dst_port=22 src_port=44688; dst_port=22 src_port=44708; dst_port=22 src_port=47644. Reported automatically from firewall/SSH logs collected by abuseipdb-reporter.
