Threat Intelligence Briefing

Global threat volume decreased significantly by 92% compared to the previous period, representing a major deviation from typical high-volume activity. This sharp decline is consistent with routine weekend patterns where automated threat activity often drops. SSH brute force remains the dominant attack vector, primarily originating from IPs in Russia, Romania, and Bulgaria. Nordic countries show stable, low-level activity consistent with their baseline, with Finland (14 events), Sweden (13), and Norway (6) experiencing typical background noise across attack, botnet, and spam categories. Defender actions should focus on maintaining standard security posture rather than reactive measures. Continue blocking known malicious ASNs and CIDR ranges associated with SSH brute force campaigns, particularly from Eastern European networks. Prioritize monitoring for emerging threats against recently patched systems, especially Cisco SD-WAN vulnerabilities outlined in CERT-EU advisory 2026-002.
