Threat Intelligence Briefing

Threat volume decreased significantly to 101,497 events, a 94.8% reduction from the previous period's 1.97 million. This represents a major deviation from typical high-volume activity, suggesting either successful mitigation efforts or temporary attacker downtime. Reconnaissance remains the dominant threat category (88,464 events), consistent with long-term patterns. The US (21,943) and China (10,791) continue as top source countries. Nordic regions show stable, low-level activity: Sweden (601), Finland (416), Norway (146), Denmark (48) and Iceland (18), primarily reconnaissance and blacklist events. Focus defensive resources on pattern-based blocking of reconnaissance clusters and SSH bruteforce attempts from ASNs hosting these activities, rather than individual IPs. The sharp decrease suggests previous mitigations may be effective; maintain vigilance for resurgence. Prioritize monitoring US-based threat clusters exhibiting high attack counts across multiple IPs.
