Threat Intelligence Briefing

Global threat volume increased 5.8% to 102,675 events compared to the previous 6-hour period, representing a meaningful deviation from baseline activity. While reconnaissance remains dominant (93,595 events), SSH brute-force attacks showed notable intensity from Vietnamese and Polish IP clusters. Nordic countries maintained stable patterns: Sweden led with 693 events primarily reconnaissance and attacks, Finland showed 350 events, Norway 216, Denmark 57, and Iceland 18—all consistent with regional baselines. The 171.243.151.216/24 subnet from Vietnam requires attention for concentrated SSH attacks. Consider temporary blocking of Vietnamese /24 ranges exhibiting SSH brute-force patterns, while Nordic activity represents routine background noise requiring no immediate action. Prioritize monitoring Vietnamese and Polish CIDR blocks showing persistent SSH attack patterns rather than individual IPs.
