Threat Intelligence Briefing

Global threat volume decreased significantly, down 86.8% compared to the previous period. This sharp decline is a deviation from the high baseline and represents a return to more typical activity levels. The threat profile remains consistent, dominated by malware C2 and various brute-force attacks. Nordic activity is minimal and routine, with Sweden seeing 7 events and Finland 2, primarily brute-force attempts. The top threat IPs, primarily from Russian and Bulgarian networks, are part of persistent SSH brute-force campaigns that have been active for weeks, not a new emergence. Focus on the clusters, not the ephemeral IPs. Consider temporarily blocking or rate-limiting traffic from known malicious ASNs in Russia, Bulgaria, and Romania that consistently generate SSH brute-force attacks. The current low volume allows teams to deprioritize immediate response to individual alerts and focus on hardening internet-facing SSH and web services against these common, persistent threats.
