Threat Intelligence Briefing

Global threat volume changed by several orders of magnitude (1,468 → 15,849 events), representing a major deviation from the previous period. This surge is not routine and is primarily driven by spam and attack categories. Nordic region volumes remain stable and consistent with their 7-day averages, with Sweden (60 events) and Finland (49) seeing typical, low-level background noise. The top threat IPs are predominantly SSH brute-forcers from Eastern Europe and the Netherlands. Focus on the pattern of SSH brute-force attacks from ASNs in NL, RO, and RU rather than ephemeral IPs. Consider implementing temporary rate-limiting or geo-blocking rules for these specific traffic patterns and ASN ranges to mitigate the global surge, while Nordic-specific activity does not warrant immediate action.
