Threat Intelligence Briefing

Threat activity remains stable globally, with only a 0.5% increase from the previous period, consistent with the 7-day average. The primary threats are SSH and web brute-force attacks, predominantly originating from Dutch (ASN 20473, 43350) and Vietnamese (ASN 7552) hosting providers. Nordic activity is routine; Sweden shows the highest volume with 16 events across diverse categories, while Norway and Finland remain at low baseline levels. The top attacking IPs are part of known, persistent campaigns, not new infrastructure. Focus on the originating ASN clusters, not the ephemeral IP addresses. Consider implementing temporary rate-limiting rules for SSH and web login endpoints, particularly for traffic originating from the top source ASNs. This is more effective than blocking individual IPs, which are frequently rotated. No immediate escalation is required.
