Threat Intelligence Briefing

Global threat volume changed by several orders of magnitude (2,277 → 108,940 events), representing a severe deviation from typical background noise. This surge is primarily driven by mass reconnaissance activity, consistent with a widespread scanning campaign. Nordic countries show elevated but proportional activity; Sweden (727 events) and Finland (403 events) lead with attack and botnet traffic, while Norway (218 events) and Denmark (71 events) remain primarily reconnaissance-focused. The top threat IPs, predominantly from Romanian (2.57.122.0/24) and Taiwanese networks, are actively conducting SSH brute-force attacks. This pattern suggests coordinated infrastructure probing rather than isolated incidents. Focus mitigation efforts on the identified /24 subnet ranges and ASNs originating from Romania and Taiwan. Consider implementing temporary SSH rate-limiting rules, particularly for internet-facing systems. Deprioritize individual IP blocking due to the campaign's distributed nature. Monitor for follow-on attack traffic originating from these reconnaissance patterns.
