Threat Intelligence Briefing

Global threat volume spiked by 148.5% compared to the previous period, reaching 275,379 events. This significant deviation from the 7-day average is primarily driven by surges in low-reputation traffic and reconnaissance activity. Nordic countries show elevated but proportional increases, with Sweden (1,602 events) and Finland (965 events) experiencing the highest volumes. The top threat actors are concentrated within specific CIDR ranges originating from Poland (87.251.64.0/24) and Vietnam, indicating coordinated SSH brute-force campaigns rather than isolated IPs. Focus mitigation efforts on blocking the identified Polish /24 CIDR range and Vietnamese ASNs associated with SSH brute-forcing. Prioritize reviewing and hardening SSH server configurations exposed to the internet. The scale of this surge warrants increased vigilance, but these campaigns represent known, persistent threats rather than novel tactics.
