Threat Intelligence Briefing

Global threat volume decreased significantly by 87.3% compared to the previous 6-hour period, representing a major deviation from the high baseline. This sharp decline is atypical and suggests a potential shift in adversary infrastructure or tactics. SSH brute force remains the dominant attack category. Nordic activity remains minimal and stable, with Sweden (10 events), Finland (7), and Denmark (4) showing routine, low-level background noise consistent with their typical baselines. No new campaigns emerged in the region. Focus analysis on the sustained SSH brute force pattern from ASNs in the Netherlands and Vietnam, rather than individual IPs which are ephemeral. Consider reviewing and maintaining existing rate-limiting rules for SSH services, particularly for internet-facing systems. The dramatic global drop does not warrant immediate new defensive actions but justifies monitoring for a potential rebound in activity.
